8 * config/tc-hppa.c: Eliminate all uses of fx_addnumber.
9 (tc_gen_reloc): Simplify. It's no longer necessary to set a
10 reloc's addend field to zero for function symbols.
11 (md_apply_fix): Simplify. For fixups which will require a SOM
12 reloc, just clear out the necessary bits in the output file.
14 Fri Oct 14 19:06:46 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
16 * Makefile.in (BISON): Use bison -y, not bison.

30 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
32 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
33 it's better to use the one in libiberty.
35 Wed Oct 12 18:48:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
37 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
38 change; it breaks the rs6000 support, and doesn't seem to be

49 rather than explicitly adding the frag address.
50 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark
51 the end of the line numbers; this replaces the zero entry which
52 used to be added by coff_add_linesym, removed Oct 7.
53 (coff_adjust_section_syms): Ignore sections with no seginfo.
55 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
57 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a

75 * Makefile.in (comparison): When comparing as.new or gasp.new, try
76 running the binary through sed to avoid differences due to
77 "stage1" or "stage2" having been written into the binary.

83 expression pointer to the symbol structure, used for `size'
84 expressions that couldn't be reduced to constants when initially

114 * config/obj-coff.h (coff_adjust_section_syms, coff_frob_file):
116 (obj_frob_file): New macro.
118 * config/obj-coff.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Renamed from

144 * Makefile.in (DISTSTUFF): New variable, listing only make-gas.com
146 (diststuff): New target; builds DISTSTUFF.
147 (realclean): Separate target, depend on clean and distclean, then
149 * make-gas.com: Deleted.
151 * config/tc-i386.c (i386_validate_fix) [BFD_ASSEMBLER]: New
152 function. Converts reloc for "foo-GOT" to BFD_RELOC_386_GOTOFF
154 (i386_operand): Don't look up section symbol for

170 referring to PLT entries.
171 * write.c (fix_new_internal): Initialize fx_plt to zero.
172 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.

175 (fixup_segment): Changed local var PCREL to type int, added PLT.
176 If PC-relative fixup refers to a PLT entry for a symbol in the
177 current section, don't reduce it.

180 DEBUG5 is defined, print out each fixup before and after
182 (fixup_segment): If DEBUG5 is defined, print out each fixup before
183 and after processing.
184 (print_fixup): Added prototype. Show address on first line. Show

193 * Makefile.in (all): Depend on .gdbinit.
194 (.gdbinit): Rebuild from gdbinit.in by running config.status.
196 * gdbinit.in: Define new function "pf". Fix doc on "pe" and "ps".
198 * write.c (print_fixup): Print source location on first line.
199 Show fx_r_type and fx_addsy fields.
201 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
203 * configure.in: Set bfd_gas for all sparc targets in one place,
204 instead of separately for each. Correctly handle user-supplied
205 "--enable-bfd-gas" option.
207 * gdbinit.in: Move "break abort" to end, in case gdb complains.
209 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
212 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
213 processing if add_symbol is undefined or in expr_section.
214 (resolve_symbol_value, case O_add): For symbol plus
215 constant-valued symbol, convert to O_symbol and re-reduce.

222 (print_expr_1): Fix whitespace before printing X_add_number.
224 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
225 not symbol_new, for symbols holding expression values.
226 * expr.h (make_expr_symbol): Move declaration here.
227 * write.c (fix_new_exp): Handle O_add by creating an
228 expression-valued symbol, and calling fix_new_exp recursively.
229 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
230 undefined symbol and a constant, fold the constant into the fixup,
231 and refer to the undefined symbol directly. Then process the
232 fixup again from scratch.
233 (write_object_file): Before calling adjust_reloc_syms, make a pass
234 through the symbol list trying to resolve values.
236 * write.c (print_fixup): New routine, for debugging.
237 (write_relocs): Call bfd_install_relocation. Deleted various
238 hacks for working around problems with bfd_perform_relocation.

246 * config/tc-mips.c: Include subsegs.h.
247 (md_apply_fix): If an unconditional b or bal overflows, and we are
248 not assembling PIC code, replace it with a j or jal.
250 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.

255 * write.c (write_relocs): Add file name and line number to
256 as_fatal calls. Handle bfd_reloc_overflow case specifically when
257 RELOC_EXPANSION_POSSIBLE.
259 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
261 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
262 here. Use them for deciding which PRINTF*LIKE macro definitions
264 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
265 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
266 default definitions matching what we were doing before.
267 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
268 always use the varargs form if not using stdarg. It's safe to
269 always use vfprintf, because libiberty will provide it if the
270 native system doesn't. Also, always make format be const.
271 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
273 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

286 (listing_newline): Check filename as well as line number when
287 deciding whether to record it.
288 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
289 false (if defined) as well as checking for reg_section.
290 (listing_listing): Iterate fetching lines while line number is too
291 low, and we haven't run off the end of the input file.
293 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
295 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

304 * config/ho-*.h: Now-unused files deleted.
306 * symbols.c (copy_symbol_attributes): New function. Copies BFD
307 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
308 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
309 zero. Don't call obj_frob_forward_symbol.
310 * read.c (pseudo_set): Call copy_symbol_attributes, but only if

312 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
314 * config/tc-i960.c: Lots of whitespace, comment reformatting,
316 (strchr): Don't declare.

319 md_create_short_jump, md_create_long_jump.
320 (brtab_emit): Use data_section, not SEG_DATA.
322 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
324 * config/vms-conf.h: new file, manually derived from conf.in.
325 * config-gas.com: use it, and eliminate obsolete "host.h".
327 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
329 * config/tc-ppc.c (ppc_current_block): New static variable.

334 (ppc_es): Clear ppc_current_block.
335 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
336 from the csect of the enclosing block.
338 * config/tc-mips.c (insns_since_cache_access): Remove.
339 (append_insn): Remove setting of insns_since_cache_access, and
340 special 4600 handling; it turns out not to be required.
342 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
344 * config/tc-mips.c (md_shortopts): Remove E.
345 (md_longopts): Add EB and EL.
346 (md_parse_option): Handle -EB and -EL as separate options, rather
347 than as a single -E option with an argument.
349 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
351 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
352 involving global symbols too.
354 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
356 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
358 * configure.in: Test for remove, not delete. Fix cross-assembler
360 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
363 * read.c (pseudo_set, case O_symbol): If
364 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.

370 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
371 many others): new macros; values obtained from "DSTRECRDS.SDL".
372 * config/obj-vms.h (various): use them.
373 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
374 representation (only enum bitfields can avoid being bitstrings).
375 (bitfield_suffix, setup_basic_type): new routines.
376 (VMS_typedef_parse): use them. Now recognize bitfields of all
377 integral types, not just type `int'. Caveat: the representation
378 used for bitfields still does not work for objects placed in
379 registers, and gcc's optimizer sometimes puts small structs there.
381 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
383 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
385 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
386 (tc_frob_label): define this to call vms_check_for_special_label,
387 and declare the latter.
388 * config/obj-vms.c (vax_g_doubles): declare this file-scope
390 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
391 (vms_check_for_special_label): new routine (tc_frob_label).
392 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
393 and `gcc2_compiled.' labels; they won't reach here any more.
394 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
395 double', use `vax_g_doubles' flag to select type of double.
396 (VMS_write_object_file) [traceback setup]: don't pass symbols
397 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
398 and TBT_Routine_End functions.
400 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
402 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
403 S_GET_VALUE() to avoid many repeated function calls.
404 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
405 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
406 gets requested. [All the HACK_DEC_C_STARTUP code appears to
407 be obsolete; gcc does it automatically for vms target. It's
408 also misnamed, because it is for the "VAX C" run-time library,
409 not the newer "DEC C" one which has much different startup code.]
410 {various}: use `S_SET_xxx(symbol,new_value)' rather than
411 `S_GET_xxx(symbol) = new_value'.
413 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
415 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,
416 not &bfd_abs_section.
418 Thu Sep 15 18:36:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
420 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
422 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
424 * expr.c (expr): Don't reduce the difference of two symbols in the
425 same frag if the symbols are not in normal sections.
427 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
428 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
429 (obj_attach_unwind_info): Do not define. Not needed anymore.
430 * config/tc-hppa.c: Delete whitespace at EOL.
431 (struct hppa_fix_struct): Delete fx_unwind field and all references.
432 (fix_new_hppa): Last arg is now a pointer to an int. Do not
433 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
434 fixups, store 32bits of unwind information in the fx_addnumber
436 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
437 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
438 pointer to 32 bits of unwind info.
439 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
440 pointer to the dummy symbol; set the addend field to fx_addnumber.
441 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
442 rather than &bfd_XXX_section.
444 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
446 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
447 value by one; discard adjustments previously being made. From
450 VMS- and Vax-related changes from Pat Rankin:
451 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
452 * vmsconf.sh: no longer have make-gas.com echo text about needing
453 to modify the gcc-vms driver when intending to use with gcc 1.x.
454 * as.c (parse_options): suppress 'v' from std_short_options and
455 eliminate VMS-specific conditional initialization;
456 [default case]: check for '-v' if md_parse_options doesn't recognize
458 [default case, #if VMS]: check for filename argument when '-v' seen;
460 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
461 for O_big literal operands (double floats and long long ints);
462 [VMS, md_shortopts]: add second colon after 'v';
463 (md_parse_options) [VMS, case 'v']: check for argument, so
464 caller can handle `-v' w/o arg.
466 Tue Sep 13 16:45:08 1994 Steve Chamberlain (sac@jonny.cygnus.com)
468 * config/obj-coff.c (do_relocs_for): If TC_KEEP_FX_OFFSET
469 is defined, put the tx_offset into the r_offset.

1515 (control_regs): New pointer.
1516 (m68k_ip): Use control_regs instead of testing CPU every time.

1887 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1889 * config/tc-mips.c (append_insn): Permit branches to be switched
1890 with the preceding instruction even if .set nobopt has been seen.
1891 .set nobopt actually controls whether to bring up an instruction
1892 from the branch target, which gas does not currently support.
1894 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1896 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

1909 * config/tc-sparc.c (md_section_align): Always round up to
1910 multiple of alignment power specified in bfd target vector.
1912 * gasp.c: Include ctype.h.

1933 * config/tc-hppa.c (pa_parse_space_stmt): Use the built-in
1934 defaults for defined, private, and spnum fields for the
1935 $TEXT$ and $PRIVATE$ spaces. Do not clobber spnum. Do
1936 not reset the segment if just updating a space.
1937 (pa_spaces_begin): Set BFD section flags for all built-in

1945 address zero, insert a dummy line to compensate.
1947 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Make gasp.new
1950 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1952 * expr.c (operand): Try to parse "0f" and "0b" sequences as
1953 floating point and binary numbers respectively; if it doesn't
1954 work, treat them as local labels.
1956 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
1957 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
1959 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
1961 * vmsconf.sh: In generated file, get ".obj" suffix right, build
1962 source files from other directories into objects in the current
1963 directory, and specify PSECT attributes explicitly to linker.
1964 Also added missing label.
1965 * Makefile.in (stamp-mk.com): Reference new variable
1966 VMS_OTHER_OBJS for list of non-local object files, instead of

1978 * Makefile.in (de-stage1, de-stage2, de-stage3): Use rm -f.
1980 * config/tc-mips.h (DIFF_EXPR_OK): Define.
1981 * config/tc-mips.c (macro_build): Permit BFD_RELOC_PCREL_LO16 for
1982 certain cases of 'i', 'j' and 'o'. Change 'u' to take an
1983 argument, the reloc type.
1984 (load_register): Pass reloc type to macro_build for 'u'.
1985 (macro): Likewise. For M_LA_AB permit a difference expression
1986 when generating embedded PIC code between an arbitrary symbol and
1987 a symbol in the .text section.
1988 (mips_force_relocation): Force BFD_RELOC_PCREL_HI16_S and
1989 BFD_RELOC_PCREL_LO16 to be emitted.

1997 * subsegs.c (subsegs_begin): Call memset with args in the correct
1999 (subseg_get): Clear newly allocated seginfo, set its pointer slots
2000 to NULL instead of 0.

2004 * config/tc-hppa.c (pa_procend): Handle case where label was
2005 defined after the .proc directive.
2007 * config/tc-hppa.c (pa_procend): Give an error if we encounter a
2008 procend for a procedure without a name.
2010 Thu Apr 7 14:28:30 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

2029 (hppa_tc_symbol): Likewise.
2031 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2032 elf_tc_make_sections stuff. It was there to support PA braindamage
2033 which has been fixed, and in the case of elf_tc_make_sections is
2034 redundant with elf_tc_final_processing.
2036 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2038 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

2043 * config/tc-mips.c (mips_ip): For case 'o', when generating
2044 embedded PIC code, accept the difference between two local symbols
2046 (mips_force_relocation): Only force a reloc to be generated for a
2048 (md_apply_fix): For BFD_RELOC_32 and BFD_RELOC_LO16, put the fixup
2049 value into the file if the fixup will not generate a reloc.
2051 Tue Apr 5 11:14:14 1994 Ken Raeburn (raeburn@rtl.cygnus.com)
2053 * config/tc-sparc.c (s_reserve): If section passed isn't bss,
2054 don't spew remainder of input file in error message.
2055 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2056 message with reloc type and try to process remainder of file.
2058 * doc/Makefile.in (install-info-as, install-info-gasp): New
2059 targets, now explicitly checking $(srcdir) for info files.
2060 (install-info): Depend on both of them; do nothing more.
2062 Mon Apr 4 17:06:04 1994 Jeffrey A. Law (law@cygnus.com)
2064 * config/tc-hppa.c (tc_gen_reloc): Fix thinko in ELF version.
2066 Mon Apr 4 12:39:23 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2068 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2069 flag rather than signedp field. Only permit extended range if
2070 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2071 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2073 * config/tc-ppc.c (ppc_size): New static variable.
2074 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2075 (md_begin): If an instruction has a size specific flag set, only
2076 add it if we are assembling that size.
2078 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2080 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2081 cross section PC relative relocs right for COFF and ELF.
2083 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2085 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.
2086 (OBJ_PROCESS_STAB): Don't define.
2088 Mon Mar 28 12:40:25 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2090 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
2091 the type of symbol set symbols which happen to be in the absolute
2092 or undefined section.
2094 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
2096 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2097 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2098 and -many (all architectures).
2100 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2102 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
2103 involving a function symbol which is not a plabel to zero.
2104 (md_apply_fix): Never pass a function symbol to field_adjust.
2106 Fri Mar 25 17:35:49 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2108 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2109 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2111 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2112 branch with an instruction that uses $at, in case the branch is
2114 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2115 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2116 to make it pcrel_offset.
2117 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2118 reloc->address; another gruesome hack to get gas reloc handling to
2121 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2123 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2126 (emit_insn): New function.
2127 (md_assemble): Call it.
2128 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2130 (lituse_pending): New variable. Set by anything that generates a
2131 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2132 tested by code that might want to emit a LITUSE reloc.
2133 (emit_unaligned_io): New function. Currently calls md_assemble,
2134 but it should eventually be converted to generate the insn itself
2135 and call emit_insn directly.
2136 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2137 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2138 emit_bis_r): Likewise.
2139 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2140 (alpha_ip, label get_macro): Don't emit the final instruction if
2142 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2143 unaligned memory access macros.
2144 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
2145 the value can't be resolved.
2147 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2149 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2150 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2151 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
2153 (mips_force_relocation): New function.
2154 (md_apply_fix): Set fixP->fx_done appropriately.
2155 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

2163 * config/tc-mips.c (enum mips_pic_level): New enum.
2164 (mips_pic): Change from int to enum mips_pic_level. Change all
2165 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2166 (load_address): Handle EMBEDDED_PIC.
2167 (macro): Handle EMBEDDED_PIC in all PIC cases.
2168 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2169 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2170 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2171 works). Do not permit -G with SVR4_PIC.
2172 (s_abicalls): Warn if -G was used, and force -G 0.
2173 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2174 anything but a.out, not just for ELF. For ECOFF, don't generate a
2175 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2177 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2179 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2181 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2182 parameters to avoid losing when compiling with HP CC.
2183 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2185 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2187 * Makefile.in (config-stamp): If `defs' is defined, emit a
2188 preprocessor directive to create a macro named by this value into
2189 config.new; don't explicitly go for BFD_ASSEMBLER.
2190 * configure.in: Define `defs', not `BFDDEF'. Set it to
2191 MANY_SEGMENTS for any obj-coffbfd target.
2192 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2193 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2195 (LOCAL_LOADLIBES): Deleted.
2196 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2197 * config/m88kcoff.mt (TDEFINES): Ditto.
2198 * config/ebmon29k.mt: Deleted.
2199 * config/h8300hds.mt: Deleted.
2200 * config/ic960coff.mt: Deleted.
2201 * config/sparc.mt: Deleted.
2202 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2203 * config/h8500.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2204 * config/sh.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.
2205 * config/z8k.mt (LOCAL_LOADLIBES): Deleted.
2206 (TDEFINES): Don't define the coffbfd macros.

2223 bfd_set_symtab is called.
2224 (dump_section_relocs): Note whether a symbol is a section symbol
2226 (adjust_reloc_syms): For now, always supply an absolute symbol for
2227 fixups without symbols but not yet `done'. Use section_symbol to
2228 get the symbol, instead of going directly for abs_symbol.
2229 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2230 reloc is not a section symbol and is not in the symbol table.
2231 (set_symtab): New function, broken out from write_object_file.
2232 Counts symbol table instead of relying on an earlier count.
2233 (write_object_file): Call set_symtab, but do it after potentially
2234 invoking the *_frob_file macros. Don't bother counting symbols.
2235 Call symbol_remove, instead of expanding it in place. Moved the
2236 conditionalized `object_file_size' declaration down to
2237 conditionalized block where it's used. When using the absolute
2238 symbol for a fixup without a symbol, set sy_used_in_reloc.
2239 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2240 the correct symbol for the absolute section.
2242 * subsegs.c (section_symbol): Use symbol_new instead of
2243 symbol_make, since we may want it to go into the symbol table.
2244 Make the new symbol have internal linkage. If
2245 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2246 symbol with the newly created GAS symbol.
2247 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2248 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:
2250 * config/obj-elf.h (obj_sec_sym_ok_for_reloc): New macro.
2252 * config/tc-sparc.c: Include subsegs.h.
2253 (in_signed_range): New function.
2255 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2256 (sparc_ip, label "immediate"): Reject constants for pcrel
2257 instructions only if the relocation type indicates a "call"
2258 instruction and the offset is within range of a "jmpl %g0". If
2259 it's not in range, use the absolute section symbol plus an offset.
2260 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2262 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2264 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2267 * configure.in: Eliminated all targets using obj-coff but not
2268 defining BFD_ASSEMBLER; I think all such targets that are
2269 supported will be matched by real CPU-OS combinations earlier in
2271 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2272 some comments about the dpx2 configuration, but left it disabled,
2273 since it couldn't be reached before.
2274 (target a29k-amd-ebmonold): Deleted.
2276 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2278 * config/tc-hppa.c (pa_import): Correctly handle importing of an
2279 already defined symbol.

2283 * config/tc-mips.c (mips_ip): Only accept overly large values for
2284 the 'j' operand if there are no further alternatives for this
2287 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2288 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2289 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2291 * config/tc-mips.c (mips_align): Take new argument, label, and use
2292 it instead of global insn_label.
2293 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2294 call to mips_emit_delay and pass it to mips_align.
2296 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2298 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2300 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2301 argument to a .callinfo directive. Don't loop forever on errors.
2303 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2304 use pre-defined registers as arguments.
2306 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2308 * write.c (write_object_file): Check both S_IS_LOCAL and
2309 S_IS_EXTERNAL when deciding whether to discard a symbol.
2311 * config-gas.com: Scan Makefile.in, not version.c, for current
2312 version number. Delete all versions of temp files when finished
2313 with them. Create config.h.
2315 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2316 values to reduce number of lookups with S_GET_VALUE. Skip debug
2317 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2318 holger@botbso.rhein-main.de.)
2319 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2320 field. (Also from Holger Teutsch.) Watch for a would-be register
2321 mask that spans frags.
2323 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2324 this_base, not line_base. (Patch from Andreas Arens,
2325 ari@obelix.av.rwth-aachen.de.)
2327 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2328 look local if they're exported or undefined. Used to be done for
2331 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2332 Get it from the looked-up symbol, instead of using the string from
2333 the input stream, which is no longer null-terminated.
2334 (LEX_PCT): New macro, defaults to 0.
2335 (lex_type): Use it for `%'.

4122 pass new argument for i, j and o cases.
4123 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

4344 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
4345 the table, require that the one without bit 0x1000000 set come

4456 OPTIONAL_REGISTER_PREFIX if either is already defined.
4458 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4460 * configure.in: Set bfd_gas for all sparc targets. Added facility
4461 for keeping or rejecting configurations still under development;
4462 default is to assume production environment, and reject configs
4463 still being worked on. Mark Elf configurations (except sparc and
4464 i386) as developmental. Deleted cases matching some generic names
4465 in favor of more specific names. (E.g., when we get Alpha

4482 through inclusion of tc-hppa.h. Delete all forward declarations
4483 for functions only used within tc-hppa.c, likewise for structures,
4484 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4485 conditional code in a few small places.
4487 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4488 structures, global variables, forward declarations together.

4490 conditional code -- try to group conditional code together
4491 into a few places. Make all functions and variables which
4492 are only used within tc-hppa.c static. PARAMize all functions.
4493 Add comments to functions. Delete unused functions, variables,
4494 #defines, etc. Delete unused members within structures. Delete
4495 ldil;ble hacks -- it is believed they were installed to work
4496 around old gas bugs. Avoid using mixed case for local
4497 functions, variables, and structures. Fix formatting problems
4498 not found by GNU-indent. Add FIXME notices for things which
4499 should be worked on the near future. Delete lots of old
4500 useless (1.36 PA-SOM) code.

4579 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4581 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4582 ELF, since the ELF object format does not have these type of
4583 relocations. Change the abort into as as_bad and return
4584 BFD_RELOC_NONE to silence compiler warnings.
4585 (md_assemble): Keep track of the instruction size. Allow white
4586 space between the $ and the constant for compatibility with older
4587 gases and other assemblers.

5596 * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
5597 are also magic, and have special default flag settings.
5598 (obj_elf_frob_symbol): Since the return value from this function
5599 isn't used, don't bother calling obj_elf_write_symbol_p, since it

5612 undefined_section for the return value.
5614 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a

5662 * Extensive changes to permit symbols to contain any expression
5663 type and to delay the computation of the expression until the
5664 value is actually needed. This permits setting symbols to values
5665 calculated based on object code size. Expressions were changed to
5666 no longer be in a section, to stop the overloading of segment and
5667 expression type that previously occurred.
5669 * as.c (big_section, pass1_section, diff_section, absent_section):
5671 (expr_section): Added (used for dummy symbols which hold

5755 (previous_section, previous_subsection): New vars.
5756 (obj_elf_section): Save current place in case DWARF code wants us
5757 to pop back to it. Handle unquoted section name as well as quoted
5758 section name. Don't crash on invalid strings.
5759 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

7071 dropping a space immediately following an identifier.
7072 * expr.c, write.c: Rewrote assert expressions to not use multiple
7073 lines; I don't think that can be done portably.
7074 * config/tc-mips.c (macro): Use $AT if target register is zero in
7075 load instruction, which it can be for a floating point load.

7149 prototypes for all static functions. Moved existing minimal
7150 debugging format support info #ifndef OBJ_ECOFF blocks.

7199 * make-gas.com: Find obstack.obj if it's not in the current
7201 * read.c (s_ignore): Don't declare is_end_of_line. It's
7202 redundant, and triggers a VMS gcc compiler bug.
7204 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7205 current segment as an argument. (Ignored in all cases but VMS.)
7206 All callers and definitions changed.

7260 constants are accepted, but symbolic values are not. GCC will not
7261 generate the latter currently.
7263 * frags.c (frag_init): New function.
7264 (zero_address_frag, bss_address_frag): Now initialized at run
7266 * as.c (main): Call frag_init.

7516 * config/tc-sparc.c (architecture_requested, warn_on_bump,
7517 md_relax_table): Use default zero initialization.
7518 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
7519 latter, instead of selecting with preprocessor conditionals.
7521 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
7523 * configure.in: recognise all sparclite variants
7525 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

7531 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
7533 * expr.c (operand): If character other than comma or newline is a
7534 logical end-of-line character, use the newline case.
7535 From Eric Youngdale:
7536 (operand): Set X_add_number field for floating-point numbers.
7537 (operand): Treat zero byte as end-of-operand.
7539 * configure.in (per-target): Look for with_bfd_assembler option.
7540 For now, only accept "no", until the merge is done.
7542 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7543 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
7544 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
7545 * read.c: Finish conversion to S_* macros in the VMS only
7546 parts of the program. Add "const" modifier to hex_value.
7547 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
7549 * expr.c: Add "const" modifier to hex_value.
7550 * symbols.c: Finish conversion to S_* macros in the VMS only
7551 parts of the program. Add "const" modifier to
7552 md_[long,short]_jump_size. Remove declaration of const_flag
7553 (which will be declared in obj-vms.h).
7554 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7555 Fix arguments to VMS_write_object_file.
7556 * config-gas.com: New file. Script for VMS systems to set up the
7557 configuration to build gas for VMS, and create config.status.
7558 * make-gas.com: Redone to work with new scheme.
7559 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
7561 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
7562 will swap bytes if needed on a big endian system. Use throughout
7564 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
7565 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7566 types of malformed stabs. Change parsing algorithm so that we are
7567 more certain of having all of the information that we need on hand.
7568 * obj-vms.c (final_forward_reference): New function, used to help
7569 resolve the data types of as many struct elements as possible
7570 when some part of the struct is not fully defined by the compiler.
7571 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
7573 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7574 as symbols as well in the object file. Look for external functions
7575 that start with "__vt.", and turn them into variables, since the
7576 g++ compiler is incapable of doing this.
7577 * tc-vax.c: Add '1' option for backward compatibility with older GCC
7579 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
7580 * input-scrub.c (as_where): Fix bug where as would crash if we did not
7581 have the name of the source file yet.
7582 * config/ho-vms.h: define HO_VMS, not HO_VAX.
7584 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
7586 * read.c (s_data): Always use "data_section", since it'll map to
7587 SEG_DATA or SEG_E1 if needed.
7588 (s_lcomm): Likewise with bss_section.
7589 (s_fill): Use memset, not bzero.
7591 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

7613 (big_section, reg_section, pass1_section, diff_section,
7614 absent_section, text_section, data_section, bss_section): If
7615 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
7616 mapping to segT enum values.
7617 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7618 if these are used or defined, if BFD_ASSEMBLER.
7619 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7620 subseg_new split into two functions.
7621 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7623 * as.h (volatile): Don't define if already defined.
7624 (had_errors, had_warnings): Provide prototypes for ANSI C even if
7626 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7627 declare with format attribute for -Wformat checking.
7629 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7631 * app.c, config/tc-*.c: Don't include read.h, since it is already
7634 * These are based on patches from Minh Tran-le
7635 <mtranle@paris.intellicorp.com>.
7636 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7637 obj_format coffbfd and gas_target i386coff for target.
7638 (i[34]86-*-isc*): New host (uses sysv).
7639 * config/i386aix.mt: Removed (no longer used).
7640 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7642 (LDFLAGS): Added, defined as -shlib.
7643 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7644 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7645 (DOT_LABEL_PREFIX): Define.
7646 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7647 name rather than L0\001.
7648 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7650 * symbols.c, symbols.h (local_bss_counter): Removed.
7651 * write.c (write_object_file): bss no longer uses
7652 local_bss_counter. Pass correct data and bss size to

7659 (size_section): Restored sanity check.
7660 (do_relocs_for): Base section address on s_paddr rather than
7661 computing it. Adjust a29k R_IHIHALF special case to account for
7662 section paddr (used to require paddr to be zero). If there are no
7663 reclos, set s_relptr to 0. Set relocation size in object_headers.
7664 (fill_section): Always set s_vaddr here, removing
7665 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7666 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7667 Set STYP_INFO for .comment.
7668 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7669 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

7671 H_{SET,GET}_* macros.
7672 (do_linenos_for): Set lineno size in object_headers.
7673 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7674 set s_vaddr here. If string_byte_count remains 4, set it back to
7675 0, and only write strings out if there are some. Call
7676 fill_section before do_relocs_for and do_linenos_for.
7677 (obj_coff_section): Handle optional quoted second argument giving
7678 section characteristics.
7679 (obj_coff_bss): Added to handle .bss.
7680 (obj_coff_ident): Added to handle .ident (puts string in .comment

7700 (do_scrub_next_char): For \", return " not '.
7701 (symbol_chars): Now const.
7703 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7704 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7706 * config/obj-coff.h: Don't use #elif.
7708 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7709 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

7735 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
7736 using ZERO_BASED_SEGMENTS.
7737 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7738 never set segment address for SEG_E2 (.bss) and don't write out
7739 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7740 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7741 definitions, and don't merge tags with non-tags. Check for .bf
7742 rather than just checking whether the second character is b and
7743 the third character is f.
7744 (obj_coff_val): gcc can generate values which we don't handle
7745 correctly; discard information for now, since it only affects the
7746 debugging information.
7747 (tag_find_or_name): Don't insert tags in the symbol table.
7748 (yank_symbols): Don't merge labels.
7749 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7932 constant will not fit in an immediate field.
7933 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

7955 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
7957 * version.c: Put conditional "const" before version_string, not
7958 before dummy function for VMS. Now version 1.91.03.
7960 * app.c (do_scrub_next_char): Need double-\ before `000' to show
7961 printed rep of null character.
7963 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
7965 * obj-coffbfd.c (write_object_file): check return value of
7968 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
7970 * Support for i386-sysv.
7971 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
7972 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
7973 be used to set them all to zero as was done before.
7974 (fill_section): segment addresses now set in write_object_file.
7975 (fill_section): Don't set STYP_NOLOAD for .bss section.
7976 (fixup_segment): 386 uses strange common symbol format.
7977 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
7978 compatibility with SVR3.2 linker.
7979 * configure.in: i386-sysv and i386-sco use coffbfd.
7981 * app.c (do_scrub_next_char): discard whitespace after a label.

7991 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
7992 support for C source listings. (obj_coff_endef): look in the right
7993 part of the symbol for the symbol name
7995 * tc-m68k.c (get_num): make it work for all segments, not just the
7998 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

8009 * tc-z8k.c: lots of bug fixes
8011 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
8013 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
8014 #elif, since it is not supported by old compilers.
8015 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
8016 couple of expressions in tc-m68k.c.
8018 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8020 * read.c (cons): If NO_RELOC is defined, use it.
8022 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
8024 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
8026 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
8027 local labels to start with a .) and set REGISTER_PREFIX to %.
8028 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

8046 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8047 sections starting from zero, rather than making them consecutive.
8048 This makes subsequent reloc calculations easier, esp if the object
8049 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8050 allocate lcomm in .data rather than in .bss. It seems that some
8051 tools can't cope with a non-zero sized bss before linkage.
8053 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8055 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

8074 * Makefile.in (install): if $(tooldir) exists, install as in
8077 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8079 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8080 .word is < -32768 or > 32767. The -J flag causes the error to be
8081 ignored. This is to catch over-sized switches generated by gcc on
8082 systems which don't support the broken .word hack.
8083 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8084 write.c (fixup_segment): check for signed .word overflow if
8085 WARN_SIGNED_OVERFLOW_WORD.

8104 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8106 * input-scrub.c (input_scrub_push): call input_file_begin, not
8108 messages.c (as_perror): print ": " between the passed in error and
8109 the strerror, like perror does.
8111 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

8114 From Steve Chamberlain:
8115 Makefile.in: Handle m68*-*-coff*.
8116 read.c, read.h: add mult argument to s_space
8118 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8119 Motorola and MIT syntax; gas can now assemble either type of
8121 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

8128 (fixup_segment) set fx_subsy to 0.
8129 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8131 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8134 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8136 * Makefile.in (LIBS): Include opcode library.

8161 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8163 * config/tc-m68k.c (init_table): Now const. Always include 68851
8164 data, so that "bc" is available to 68040 cache instructions.
8165 Added "tt0", "tt1", and 68ec030 variants.
8166 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8167 (enum _register): Added TT0, TT1.
8168 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
8169 line number correctly in "internal error" messages. Don't print
8170 architecture-mismatch message for operand errors.
8172 From Colin Smith (colin@wrs.com):
8173 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
8174 than install_operand.

8195 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8196 has already been formatted (but may still contain %-characters).
8199 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8201 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8202 written with indirection on the last two operands, which can be
8203 either data or address registers. Added a new operand type 'r'
8204 which accepts either register type. Added '(' to notend stuff in
8205 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8436 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
8438 * as.c, write.c: use -K rather than -k for the broken word warning
8441 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
8443 * Makefile.in: do not print recursion lines.
8445 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8447 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
8449 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8451 * write.c (write_object_file): For b.out format, round up section
8452 start addresses to match required alignment.
8454 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8456 * Makefile.in (install): Install into $(tooldir)/bin, since that's
8457 where gcc looks for it.
8459 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
8461 * Makefile.in: Changed some lines to be less confusing for some
8464 * input-file.c: Conditionalize on _IOFBF, not VMS.
8466 * read.c, write.c: Change a series of ifdef/elif to
8467 ifdef/else/ifdef etc.
8469 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
8471 * symbols.c (fb_label_init): fix sizeof to memset.
8473 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
8475 * Makefile.in: install the man page.
8477 * Makefile.in: pass down MAKEINFO explicitly on info.
8479 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
8481 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8483 * flonum-const.c: renamed flonum-konst.c to stop dos name
8486 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
8488 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
8489 tc-m68k.h to te-sun3.h.
8491 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
8493 * configure.in: vxworks68 gets te-sun3.h.
8495 * expr.c: remove limitation that local_labels_dollar or
8496 local_labels_fb must be < 10.
8498 * symbols.c: remove local_labels_dollar, replace with a function
8499 interface for a sparse array. All users adjusted.
8501 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
8503 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8505 * doc/Makefile.in: commented out line for building as-all.texinfo.
8508 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
8510 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
8512 * Makefile.in: added check target.
8514 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8516 * Makefile.in: added tooldir and program_prefix.
8518 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
8520 * write.{c,h} (fix_new): Make these declarations consistent.
8522 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
8524 * Makefile.in (strerror.o): Add rule so that broken Sun make can
8527 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
8529 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
8531 * expr.c (operand): if can't work out what sort of operand it is,
8532 then look through FLT_CHARS for a hint.
8534 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
8536 * Makefile.in, configure.in: removed traces of namesubdir,
8537 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8538 copyrights to '92, changed some from Cygnus to FSF.
8540 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
8541 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8542 copyrights to '92, changed some from Cygnus to FSF.
8544 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8546 * expr.c: If an expression is single comma, then return with
8547 SEG_ABSENT rather than an error - since the sparc front end does
8548 really strange things with things like fbge,a
8550 * as.h: include bfd.h if using many sections
8551 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8552 local labels didn't work.
8553 * listing.c (list_symbol_table): don't core dump when there's no
8555 * write.c, write.h: call fix_new with the right number of args on
8557 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8560 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8562 * app.c: MRI compatibility - allow single quote to start a string.
8563 * as.c: fix typo recently introduced.
8564 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8565 * expr.c: Much rewriting, to accomodate MRI syntax for
8566 expressions. Also easier to read now.
8567 * listing.c: Put back defuns
8568 * read.c: modified to accept MRI syntax, put back listing pseudo
8569 ops so that an assembler built with NO_LISTING ignores list ops
8571 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8572 machine is a SPARC or a 29K.
8573 * config/obj-aout.c: added s_sect pseudo op
8574 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8575 fill in the timestamp.
8576 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8577 anymore, define all the relocs which the tc-<x> bit will use so we
8578 can translate from them to the coff types.
8579 * config/tc-a29k.c: reloc_type isn't ane enum any more
8580 * config/tc-m68k.c: Added NO_RELOC definition.
8582 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8584 * Makefile.in: put header files before C source for TAGS; remove
8585 references to non-existent syscalls.h.
8587 * read.c, write.c subsegs.c: back out the .bss changes.
8589 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8591 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8595 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8597 * symbols.c (local_label_name): symbols now start with ^A.
8599 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8600 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8601 generate these sections. .align: will use NOP_OPCODE or 0
8602 for padding. This is just for being nice to the
8605 * expr.c (operand): changed to generate local label "\001L0"
8606 starting with a ^A so that it is recognized as a local label.
8608 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8610 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8611 i/o opcodes - inb, inw, outb and outw. string manipulation with
8612 att syntax - scmp, slod, smov, ssca, ssto.
8614 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8615 to just after .file .
8617 In obj_crawl_symbol_chain() where it tries to put the external
8618 symbols apart, with the condition:
8619 (!S_IS_DEFINED(symbolP) &&
8620 !S_IS_DEBUG(symbolP) &&
8621 !SF_GET_STATICS(symbolP))
8622 it was moving too many symbols out. So I switch it back to the
8624 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8626 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8627 so that we don't use the F_RELFLG which make the linker complain
8628 that somebody has stripped the relocation info.
8630 Also, the AIX ld program require that the relocation table
8631 is sorted by r_vaddr like the standard ATT assembler does.
8633 [he also changed the sizeof(struct ...)'s into the coff
8634 style FOOSZ macros. I'm not sure this is right, but I can't
8635 remember why. xoxorich.]
8637 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
8639 * Makefile.in, configure.in, doc: use the doc. Build it, install
8642 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
8644 * read.c: white space and comments only.
8646 * configure.in: use the new atof-ns32.c for ns32k.
8648 * write.c: comment change only.
8650 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8651 aren't yet integrated.
8653 * tc-i860.[hc]: blew off the dust. Something must still be done
8654 about conflicting relocation types.
8656 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8659 * tc-i960.c, tc-sparc.c: white space and comments only.
8661 * tc-a29k.h: delete duplicate macro definition.
8663 * new file atof-ns32k.c copied from hack's last unreleased gas.
8665 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8667 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8670 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8671 ChangeLog's prior to this are sketchy at best. I have logs.
8672 They just aren't ChangeLogs.
8679 version-control: never
