1 Wed Oct 12 16:33:38 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
3 * config/cplus-dem.c: Removed. It isn't used. Even if it was,
4 it's better to use the one in libiberty.

8 * symbols.c (resolve_symbol_value, case O_symbol): Undo last
9 change; it breaks the rs6000 support, and doesn't seem to be
12 Wed Oct 12 11:56:50 1994 J.T. Conklin (jtc@phishhead.cygnus.com)
14 * config/tc-i386.h,te-netbsd532.h (TARGET_FORMAT): Changed to

19 * config/tc-ppc.c (ppc_fix_adjustable): Resolve symbol values
20 rather than explicitly adding the frag address.
21 * config/obj-coff.c (coff_frob_symbol): Add a zero entry to mark
22 the end of the line numbers; this replaces the zero entry which
23 used to be added by coff_add_linesym, removed Oct 7.
24 (coff_adjust_section_syms): Ignore sections with no seginfo.
26 Wed Oct 12 01:41:37 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
28 * Makefile.in (bootstrap, bootstrap2, bootstrap3): Create a

40 * config/tc-mips.c (mips_ip): Don't use S_IS_LOCAL when checking
41 for an embedded PIC switch expression, since the definition of
42 S_IS_LOCAL was changed.
44 Tue Oct 11 15:05:11 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
46 * Makefile.in (comparison): When comparing as.new or gasp.new, try
47 running the binary through sed to avoid differences due to
48 "stage1" or "stage2" having been written into the binary.
50 Sat Oct 8 01:48:04 1994 Ken Raeburn (raeburn@kr-pc.cygnus.com)
52 ELF symbol size handling, based on code from Eric Youngdale:

55 expressions that couldn't be reduced to constants when initially
57 (elf_frob_symbol): Declare.
58 (obj_frob_symbol): Call elf_frob_symbol always, rather than
59 ecoff_frob_symbol only if ECOFF_DEBUGGING defined.
60 * config/obj-elf.c (obj_symbol_new_hook): Deleted unused code.

85 * config/obj-coff.h (coff_adjust_section_syms, coff_frob_file):
87 (obj_frob_file): New macro.
89 * config/obj-coff.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Renamed from

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

141 referring to PLT entries.
142 * write.c (fix_new_internal): Initialize fx_plt to zero.
143 (adjust_reloc_syms): Re-fetch `sym' after top of reduction loop.
144 Don't adjust fx_offset by frag address, since S_GET_VALUE now

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

151 DEBUG5 is defined, print out each fixup before and after
153 (fixup_segment): If DEBUG5 is defined, print out each fixup before
154 and after processing.

164 * Makefile.in (all): Depend on .gdbinit.
165 (.gdbinit): Rebuild from gdbinit.in by running config.status.
167 * gdbinit.in: Define new function "pf". Fix doc on "pe" and "ps".
169 * write.c (print_fixup): Print source location on first line.
170 Show fx_r_type and fx_addsy fields.
172 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
174 * configure.in: Set bfd_gas for all sparc targets in one place,

178 * gdbinit.in: Move "break abort" to end, in case gdb complains.
180 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
183 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
184 processing if add_symbol is undefined or in expr_section.
185 (resolve_symbol_value, case O_add): For symbol plus
186 constant-valued symbol, convert to O_symbol and re-reduce.

191 Print segment name. Don't call print_expr_1 on an undefined
193 (print_expr_1): Fix whitespace before printing X_add_number.
195 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
196 not symbol_new, for symbols holding expression values.
197 * expr.h (make_expr_symbol): Move declaration here.
198 * write.c (fix_new_exp): Handle O_add by creating an
199 expression-valued symbol, and calling fix_new_exp recursively.
200 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
201 undefined symbol and a constant, fold the constant into the fixup,
202 and refer to the undefined symbol directly. Then process the
203 fixup again from scratch.
204 (write_object_file): Before calling adjust_reloc_syms, make a pass
205 through the symbol list trying to resolve values.
207 * write.c (print_fixup): New routine, for debugging.
208 (write_relocs): Call bfd_install_relocation. Deleted various
209 hacks for working around problems with bfd_perform_relocation.

213 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
215 * Makefile.in (gasp.o): Depends upon config.h.
217 * config/tc-mips.c: Include subsegs.h.
218 (md_apply_fix): If an unconditional b or bal overflows, and we are
219 not assembling PIC code, replace it with a j or jal.
221 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
222 Use as_bad_where and as_warn_where rather than as_bad and as_warn.

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

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

275 * config/ho-*.h: Now-unused files deleted.
277 * symbols.c (copy_symbol_attributes): New function. Copies BFD
278 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
279 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
280 zero. Don't call obj_frob_forward_symbol.
281 * read.c (pseudo_set): Call copy_symbol_attributes, but only if

283 * config/obj-elf.h (obj_frob_forward_symbol): Deleted.
285 * config/tc-i960.c: Lots of whitespace, comment reformatting,
287 (strchr): Don't declare.
288 [BFD_ASSEMBLER]: Don't compile md_convert_frag,
289 md_estimate_size_before_relax, md_ri_to_chars,
290 md_create_short_jump, md_create_long_jump.
291 (brtab_emit): Use data_section, not SEG_DATA.
293 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
295 * config/vms-conf.h: new file, manually derived from conf.in.
296 * config-gas.com: use it, and eliminate obsolete "host.h".
298 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
300 * config/tc-ppc.c (ppc_current_block): New static variable.

305 (ppc_es): Clear ppc_current_block.
306 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
307 from the csect of the enclosing block.
309 * config/tc-mips.c (insns_since_cache_access): Remove.
310 (append_insn): Remove setting of insns_since_cache_access, and
311 special 4600 handling; it turns out not to be required.
313 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
315 * config/tc-mips.c (md_shortopts): Remove E.
316 (md_longopts): Add EB and EL.
317 (md_parse_option): Handle -EB and -EL as separate options, rather
318 than as a single -E option with an argument.
320 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
322 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
323 involving global symbols too.
325 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
327 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
329 * configure.in: Test for remove, not delete. Fix cross-assembler
331 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
334 * read.c (pseudo_set, case O_symbol): If
335 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.

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

439 * config/obj-coff.c (do_relocs_for): If TC_KEEP_FX_OFFSET

448 * flonum-konst.c: Change preprocessor tests of HO_VMS to just VMS.
449 * hex-value.c: Ditto.
450 * config/obj-vms.c: Ditto.
452 * config/tc-sparc.c (sparc_ip): Replace as_bad/exit sequence with

1431 * read.c (emit_expr): Use memset to zero out memory, rather than
1432 going through md_number_to_chars. This permits handling symbolic
1433 arguments when the size is larger than sizeof (valueT), if
1434 TC_CONS_FIX_NEW is prepared to handle the case (as it is on MIPS).
1436 Fri Jun 3 12:50:13 1994 David J. MacKenzie (djm@rtl.cygnus.com)

1464 md_parse_option. Remove md_parse_long_option.
1465 * config/tc-ns32k.c: Rename `struct option' to `struct ns32k_option'.
1466 * config/tc-i386.h: Don't define md_parse_option.

1486 (control_regs): New pointer.
1487 (m68k_ip): Use control_regs instead of testing CPU every time.
1488 Use last_movec_reg too. In error messages, handle 68060, and
1489 print 68060 for mfloat, too.
1490 (m68k_init_after_args): Handle "68060". Use m68040up for making
1491 m68851 choice. Set control_regs.

1496 [DIFF_EXPR_OK]: Do conversion to pc-relative for difference, even
1497 if pcrel is already set.
1499 * read.c (potable): Add this_gcc_requires_the_gnu_assembler in all

1506 * config/tc-alpha.c (machine): New variable.
1507 (load_insn): New macro.
1508 (load_insn_table): New function.
1509 (md_begin): Call load_insn_table, once for basic instructions and
1510 once for appropriate PAL instruction table.

1533 * config/obj-vms.c: Replaced unchecked uses of malloc with
1536 * listing.c (list_symbol_table): Only test BFD64, not
1539 * config/obj-coff.c (fixup_segment) [BFD_ASSEMBLER]
1540 [DIFF_EXPR_OK]: Don't check pcrel, just convert it.

1559 VMS debugger now recognizes `long long' variables correctly.
1560 * config/obj-vms.c (VMS_typedef_parse) [case 'r']: add entries
1561 for gcc2's predefined types "long double" (same as double, as
1562 per gcc's current state), "long long int", "long long unsigned
1563 int", and final `otherwise' case (to avoid uninitialized type
1564 and size fields). [caveat: predefined types "complex int",
1565 "complex float", "complex double", and "complex long double" are
1568 * config/ho-vms.h (EXIT_FAILURE): define as 0x10000002 instead
1569 of 0, because the latter indicates success rather than failure

1573 hardcoded `0xa3's with macro DBG_S_C_ADVANCED_TYPE from obj-vms.h.
1574 (VMS_typedef_parse): eliminate redundant if-then-else when
1575 allocating new symbol entry and linking it to VMS_Symbol_type_list.
1577 Tue May 17 20:47:31 1994 Pat Rankin (rankin@eql.caltech.edu)
1579 * config/obj-vms.c (Write_VMS_MHD_Records): don't try to interpret

1805 can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum
1807 (make_pcrel_absolute) [NO_PCREL_RELOCS]: New function.
1808 (tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
1809 R_DIR16, and R_DIR32 relocs.

1861 with the preceding instruction even if .set nobopt has been seen.
1862 .set nobopt actually controls whether to bring up an instruction
1863 from the branch target, which gas does not currently support.
1865 Wed Apr 20 18:46:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1867 * config/obj-coff.h, config/obj-coff.c: Deleted all code used only

1928 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
1930 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>

2000 (hppa_tc_symbol): Likewise.
2002 * config/obj-elf.c (elf_frob_file): Delete elf_tc_symbol and
2003 elf_tc_make_sections stuff. It was there to support PA braindamage
2004 which has been fixed, and in the case of elf_tc_make_sections is
2005 redundant with elf_tc_final_processing.
2007 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2009 * configure.in (hppa*-*-*elf*): Don't require "-hp-" for the

2025 don't spew remainder of input file in error message.
2026 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
2027 message with reloc type and try to process remainder of file.

2039 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
2040 flag rather than signedp field. Only permit extended range if
2041 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
2042 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
2044 * config/tc-ppc.c (ppc_size): New static variable.
2045 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
2046 (md_begin): If an instruction has a size specific flag set, only
2047 add it if we are assembling that size.
2049 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2051 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
2052 cross section PC relative relocs right for COFF and ELF.
2054 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2056 * config/obj-coff.h (SEPARATE_STAB_SECTIONS): Always define.

2061 * config/obj-aout.c (obj_aout_frob_symbols): Don't let BFD clobber
2062 the type of symbol set symbols which happen to be in the absolute
2063 or undefined section.

2067 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
2068 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
2069 and -many (all architectures).
2071 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2073 * config/tc-hppa.c (tc_gen_reloc): Set addend for relocation
2074 involving a function symbol which is not a plabel to zero.
2075 (md_apply_fix): Never pass a function symbol to field_adjust.

2079 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
2080 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
2082 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
2083 branch with an instruction that uses $at, in case the branch is
2085 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
2086 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
2087 to make it pcrel_offset.
2088 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
2089 reloc->address; another gruesome hack to get gas reloc handling to
2092 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2094 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
2097 (emit_insn): New function.
2098 (md_assemble): Call it.
2099 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
2101 (lituse_pending): New variable. Set by anything that generates a
2102 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
2103 tested by code that might want to emit a LITUSE reloc.
2104 (emit_unaligned_io): New function. Currently calls md_assemble,
2105 but it should eventually be converted to generate the insn itself
2106 and call emit_insn directly.
2107 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
2108 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
2109 emit_bis_r): Likewise.
2110 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
2111 (alpha_ip, label get_macro): Don't emit the final instruction if
2113 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
2114 unaligned memory access macros.
2115 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
2116 the value can't be resolved.
2118 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2120 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
2121 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
2122 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
2124 (mips_force_relocation): New function.
2125 (md_apply_fix): Set fixP->fx_done appropriately.
2126 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

2134 * config/tc-mips.c (enum mips_pic_level): New enum.
2135 (mips_pic): Change from int to enum mips_pic_level. Change all
2136 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
2137 (load_address): Handle EMBEDDED_PIC.
2138 (macro): Handle EMBEDDED_PIC in all PIC cases.
2139 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
2140 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
2141 -non_shared to use NO_PIC (this is how the Irix 5 assembler
2142 works). Do not permit -G with SVR4_PIC.
2143 (s_abicalls): Warn if -G was used, and force -G 0.
2144 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
2145 anything but a.out, not just for ELF. For ECOFF, don't generate a
2146 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
2148 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
2150 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2152 * config/tc-hppa.c (create_new_space): Use ints, not chars as
2153 parameters to avoid losing when compiling with HP CC.
2154 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
2156 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2158 * Makefile.in (config-stamp): If `defs' is defined, emit a
2159 preprocessor directive to create a macro named by this value into
2160 config.new; don't explicitly go for BFD_ASSEMBLER.
2161 * configure.in: Define `defs', not `BFDDEF'. Set it to
2162 MANY_SEGMENTS for any obj-coffbfd target.
2163 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
2164 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
2166 (LOCAL_LOADLIBES): Deleted.
2167 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
2168 * config/m88kcoff.mt (TDEFINES): Ditto.
2169 * config/ebmon29k.mt: Deleted.
2170 * config/h8300hds.mt: Deleted.

2172 * config/sparc.mt: Deleted.
2173 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

2194 bfd_set_symtab is called.
2195 (dump_section_relocs): Note whether a symbol is a section symbol
2197 (adjust_reloc_syms): For now, always supply an absolute symbol for
2198 fixups without symbols but not yet `done'. Use section_symbol to
2199 get the symbol, instead of going directly for abs_symbol.
2200 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2201 reloc is not a section symbol and is not in the symbol table.
2202 (set_symtab): New function, broken out from write_object_file.
2203 Counts symbol table instead of relying on an earlier count.
2204 (write_object_file): Call set_symtab, but do it after potentially
2205 invoking the *_frob_file macros. Don't bother counting symbols.
2206 Call symbol_remove, instead of expanding it in place. Moved the
2207 conditionalized `object_file_size' declaration down to
2208 conditionalized block where it's used. When using the absolute
2209 symbol for a fixup without a symbol, set sy_used_in_reloc.
2210 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2211 the correct symbol for the absolute section.
2213 * subsegs.c (section_symbol): Use symbol_new instead of
2214 symbol_make, since we may want it to go into the symbol table.
2215 Make the new symbol have internal linkage. If
2216 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2217 symbol with the newly created GAS symbol.
2218 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2219 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2224 (in_signed_range): New function.
2226 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2227 (sparc_ip, label "immediate"): Reject constants for pcrel
2228 instructions only if the relocation type indicates a "call"
2229 instruction and the offset is within range of a "jmpl %g0". If
2230 it's not in range, use the absolute section symbol plus an offset.
2231 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2233 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2235 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2238 * configure.in: Eliminated all targets using obj-coff but not
2239 defining BFD_ASSEMBLER; I think all such targets that are
2240 supported will be matched by real CPU-OS combinations earlier in
2242 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2243 some comments about the dpx2 configuration, but left it disabled,
2244 since it couldn't be reached before.
2245 (target a29k-amd-ebmonold): Deleted.
2247 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2255 the 'j' operand if there are no further alternatives for this
2258 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2259 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2260 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2262 * config/tc-mips.c (mips_align): Take new argument, label, and use
2263 it instead of global insn_label.
2264 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2265 call to mips_emit_delay and pass it to mips_align.
2267 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2269 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2271 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2272 argument to a .callinfo directive. Don't loop forever on errors.
2274 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2275 use pre-defined registers as arguments.

2279 * write.c (write_object_file): Check both S_IS_LOCAL and
2280 S_IS_EXTERNAL when deciding whether to discard a symbol.
2282 * config-gas.com: Scan Makefile.in, not version.c, for current
2283 version number. Delete all versions of temp files when finished
2284 with them. Create config.h.
2286 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2287 values to reduce number of lookups with S_GET_VALUE. Skip debug
2288 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2289 holger@botbso.rhein-main.de.)
2290 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2291 field. (Also from Holger Teutsch.) Watch for a would-be register
2292 mask that spans frags.
2294 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2295 this_base, not line_base. (Patch from Andreas Arens,
2296 ari@obelix.av.rwth-aachen.de.)
2298 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2299 look local if they're exported or undefined. Used to be done for
2302 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2303 Get it from the looked-up symbol, instead of using the string from
2304 the input stream, which is no longer null-terminated.
2305 (LEX_PCT): New macro, defaults to 0.
2306 (lex_type): Use it for `%'.
2308 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
2309 (vip_op): Now static, and returns void. Callers changed. Added
2311 (vip): Ditto. Call as_fatal directly if a program bug is

3943 Delete dead code. Simplify.
3944 (md_apply_fix_1): Use CHECK_FIELD to verify any fixes that are
3945 applied are in range. Use bfd_put_32 rather than inserting each

4017 predefined register table.
4018 (pa_parse_number): Handle %rp in common register shortcut code.
4019 Consistently set return value to -1 for an error. Clean up error

4024 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
4025 standard hpux include files to pick up various function decls.
4027 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

4039 so GAS can attach unwind descriptor information to a BFD symbol.
4040 * config/tc-hppa.c (fix_new_hppa): If necessary attach unwind
4041 descriptor information to the BFD symbol.
4042 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

4060 of interest to the linker. ENTRY/EXIT relocations for SOM are
4061 an example of marker relocations.
4062 * write.c (write_relocs): Instead of assuming size of a relocation
4063 is 4 bytes, pick up the size from relocation itself.

4093 pass new argument for i, j and o cases.
4094 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

4177 text, data, and bss segments with new ones.
4178 (create_new_subspace): When not using aliases each subspace has a
4179 section/segment and subsegments are not needed, so set the subsegment

4315 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
4316 the table, require that the one without bit 0x1000000 set come
4317 first. Require further that it be case 'b' or 'P'. The a29k
4318 opcode table already meets these constraints.
4319 (machine_ip): When handling case 'i' or 'A', make sure that the
4320 appropriate opcode really exists by looking at the next entry in

4375 * write.c (write_relocs): For relocs that are pc_relative and
4376 pcrel_offset and not partial_inplace, adjust reloc->addend to

4427 OPTIONAL_REGISTER_PREFIX if either is already defined.
4429 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4431 * configure.in: Set bfd_gas for all sparc targets. Added facility
4432 for keeping or rejecting configurations still under development;
4433 default is to assume production environment, and reject configs
4434 still being worked on. Mark Elf configurations (except sparc and
4435 i386) as developmental. Deleted cases matching some generic names
4436 in favor of more specific names. (E.g., when we get Alpha

4453 through inclusion of tc-hppa.h. Delete all forward declarations
4454 for functions only used within tc-hppa.c, likewise for structures,
4455 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4456 conditional code in a few small places.
4458 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4459 structures, global variables, forward declarations together.

4461 conditional code -- try to group conditional code together
4462 into a few places. Make all functions and variables which
4463 are only used within tc-hppa.c static. PARAMize all functions.
4464 Add comments to functions. Delete unused functions, variables,
4465 #defines, etc. Delete unused members within structures. Delete
4466 ldil;ble hacks -- it is believed they were installed to work
4467 around old gas bugs. Avoid using mixed case for local
4468 functions, variables, and structures. Fix formatting problems
4469 not found by GNU-indent. Add FIXME notices for things which
4470 should be worked on the near future. Delete lots of old
4471 useless (1.36 PA-SOM) code.
4473 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
4474 field of the fixS structure. Needed to build unwind

4500 a multiple of the section alignment rather than always a
4503 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4504 bits are zero (eg they specify no relocations), then do not even
4505 bother adding their entries to thesymextn section.

4550 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4552 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4553 ELF, since the ELF object format does not have these type of
4554 relocations. Change the abort into as as_bad and return
4555 BFD_RELOC_NONE to silence compiler warnings.
4556 (md_assemble): Keep track of the instruction size. Allow white
4557 space between the $ and the constant for compatibility with older
4558 gases and other assemblers.

5570 isn't used, don't bother calling obj_elf_write_symbol_p, since it
5571 doesn't accomplish anything else.
5573 * config/tc-sparc.c (md_section_align): Round up section size only
5576 * symbols.c: Don't define DEBUG by default.

5583 undefined_section for the return value.
5585 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
5586 pseudo-op with a poc_handler field of NULL, ignore it and treat it
5587 as an instruction instead.

5603 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
5604 case to set obj_format=elf. Must go before i386-*-sysv* case that
5605 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
5606 *-*-solaris case, and move to before *-sysv* case that wants to
5607 set obj_format to coff.

5633 * Extensive changes to permit symbols to contain any expression
5634 type and to delay the computation of the expression until the
5635 value is actually needed. This permits setting symbols to values
5636 calculated based on object code size. Expressions were changed to
5637 no longer be in a section, to stop the overloading of segment and
5638 expression type that previously occurred.
5640 * as.c (big_section, pass1_section, diff_section, absent_section):
5642 (expr_section): Added (used for dummy symbols which hold

5726 (previous_section, previous_subsection): New vars.
5727 (obj_elf_section): Save current place in case DWARF code wants us
5728 to pop back to it. Handle unquoted section name as well as quoted
5729 section name. Don't crash on invalid strings.
5730 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
5733 * config/obj-elf.h: Don't include struc-symbol.h.

5752 calculating opP->isiz; this permits the expression size to be
5753 determined as well, later on.

5842 sy_resolved and sy_resolving single bit fields.
5843 * symbols.c (symbol_new): Don't initialize sy_forward field.

7170 * make-gas.com: Find obstack.obj if it's not in the current
7172 * read.c (s_ignore): Don't declare is_end_of_line. It's
7173 redundant, and triggers a VMS gcc compiler bug.
7175 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7176 current segment as an argument. (Ignored in all cases but VMS.)
7177 All callers and definitions changed.

7231 constants are accepted, but symbolic values are not. GCC will not
7232 generate the latter currently.
7234 * frags.c (frag_init): New function.
7235 (zero_address_frag, bss_address_frag): Now initialized at run
7237 * as.c (main): Call frag_init.

7487 * config/tc-sparc.c (architecture_requested, warn_on_bump,
7488 md_relax_table): Use default zero initialization.
7489 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
7490 latter, instead of selecting with preprocessor conditionals.
7492 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
7494 * configure.in: recognise all sparclite variants
7496 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
7498 * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --
7499 accidentally changed to use subseg_change where it should have
7502 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
7504 * expr.c (operand): If character other than comma or newline is a
7505 logical end-of-line character, use the newline case.
7506 From Eric Youngdale:
7507 (operand): Set X_add_number field for floating-point numbers.
7508 (operand): Treat zero byte as end-of-operand.
7510 * configure.in (per-target): Look for with_bfd_assembler option.
7511 For now, only accept "no", until the merge is done.
7513 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7514 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
7515 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
7516 * read.c: Finish conversion to S_* macros in the VMS only
7517 parts of the program. Add "const" modifier to hex_value.
7518 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
7520 * expr.c: Add "const" modifier to hex_value.
7521 * symbols.c: Finish conversion to S_* macros in the VMS only
7522 parts of the program. Add "const" modifier to
7523 md_[long,short]_jump_size. Remove declaration of const_flag
7524 (which will be declared in obj-vms.h).
7525 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7526 Fix arguments to VMS_write_object_file.
7527 * config-gas.com: New file. Script for VMS systems to set up the
7528 configuration to build gas for VMS, and create config.status.
7529 * make-gas.com: Redone to work with new scheme.
7530 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
7532 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
7533 will swap bytes if needed on a big endian system. Use throughout
7535 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
7536 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7537 types of malformed stabs. Change parsing algorithm so that we are
7538 more certain of having all of the information that we need on hand.
7539 * obj-vms.c (final_forward_reference): New function, used to help
7540 resolve the data types of as many struct elements as possible
7541 when some part of the struct is not fully defined by the compiler.
7542 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
7544 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7545 as symbols as well in the object file. Look for external functions
7546 that start with "__vt.", and turn them into variables, since the
7547 g++ compiler is incapable of doing this.
7548 * tc-vax.c: Add '1' option for backward compatibility with older GCC
7550 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
7551 * input-scrub.c (as_where): Fix bug where as would crash if we did not
7552 have the name of the source file yet.
7553 * config/ho-vms.h: define HO_VMS, not HO_VAX.
7555 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
7557 * read.c (s_data): Always use "data_section", since it'll map to
7558 SEG_DATA or SEG_E1 if needed.
7559 (s_lcomm): Likewise with bss_section.
7560 (s_fill): Use memset, not bzero.
7562 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
7564 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

7578 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
7579 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

7583 (section_alignment): Declare only if not BFD_ASSEMBLER.
7584 (big_section, reg_section, pass1_section, diff_section,
7585 absent_section, text_section, data_section, bss_section): If
7586 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
7587 mapping to segT enum values.
7588 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7589 if these are used or defined, if BFD_ASSEMBLER.
7590 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7591 subseg_new split into two functions.
7592 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7594 * as.h (volatile): Don't define if already defined.
7595 (had_errors, had_warnings): Provide prototypes for ANSI C even if
7597 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
7598 declare with format attribute for -Wformat checking.
7600 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7602 * app.c, config/tc-*.c: Don't include read.h, since it is already
7605 * These are based on patches from Minh Tran-le
7606 <mtranle@paris.intellicorp.com>.
7607 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
7608 obj_format coffbfd and gas_target i386coff for target.
7609 (i[34]86-*-isc*): New host (uses sysv).
7610 * config/i386aix.mt: Removed (no longer used).
7611 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
7613 (LDFLAGS): Added, defined as -shlib.
7614 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
7615 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7616 (DOT_LABEL_PREFIX): Define.
7617 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
7618 name rather than L0\001.
7619 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7621 * symbols.c, symbols.h (local_bss_counter): Removed.
7622 * write.c (write_object_file): bss no longer uses
7623 local_bss_counter. Pass correct data and bss size to
7624 VMS_write_object_file.

7630 (size_section): Restored sanity check.
7631 (do_relocs_for): Base section address on s_paddr rather than
7632 computing it. Adjust a29k R_IHIHALF special case to account for
7633 section paddr (used to require paddr to be zero). If there are no
7634 reclos, set s_relptr to 0. Set relocation size in object_headers.
7635 (fill_section): Always set s_vaddr here, removing
7636 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7637 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7638 Set STYP_INFO for .comment.
7639 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7640 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

7642 H_{SET,GET}_* macros.
7643 (do_linenos_for): Set lineno size in object_headers.
7644 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7645 set s_vaddr here. If string_byte_count remains 4, set it back to
7646 0, and only write strings out if there are some. Call
7647 fill_section before do_relocs_for and do_linenos_for.
7648 (obj_coff_section): Handle optional quoted second argument giving
7649 section characteristics.
7650 (obj_coff_bss): Added to handle .bss.
7651 (obj_coff_ident): Added to handle .ident (puts string in .comment

7657 adjustment (already happened only for common symbols, but this is
7659 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

7671 (do_scrub_next_char): For \", return " not '.
7672 (symbol_chars): Now const.
7674 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7675 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7677 * config/obj-coff.h: Don't use #elif.
7679 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7680 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

7706 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
7707 using ZERO_BASED_SEGMENTS.
7708 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7709 never set segment address for SEG_E2 (.bss) and don't write out
7710 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7711 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7712 definitions, and don't merge tags with non-tags. Check for .bf
7713 rather than just checking whether the second character is b and
7714 the third character is f.
7715 (obj_coff_val): gcc can generate values which we don't handle
7716 correctly; discard information for now, since it only affects the
7717 debugging information.

7719 (yank_symbols): Don't merge labels.
7720 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7961 fix i960+non-bfd coff bit rot.
7962 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
7963 support for C source listings. (obj_coff_endef): look in the right
7964 part of the symbol for the symbol name
7966 * tc-m68k.c (get_num): make it work for all segments, not just the
7969 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
7971 * configure.in: recognize i386-*-bsd emulation.

7980 * tc-z8k.c: lots of bug fixes
7982 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7984 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7985 #elif, since it is not supported by old compilers.
7986 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7987 couple of expressions in tc-m68k.c.
7989 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7991 * read.c (cons): If NO_RELOC is defined, use it.
7993 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
7995 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
7997 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
7998 local labels to start with a .) and set REGISTER_PREFIX to %.
7999 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

8017 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
8018 sections starting from zero, rather than making them consecutive.
8019 This makes subsequent reloc calculations easier, esp if the object
8020 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
8021 allocate lcomm in .data rather than in .bss. It seems that some
8022 tools can't cope with a non-zero sized bss before linkage.
8024 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8026 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

8045 * Makefile.in (install): if $(tooldir) exists, install as in
8048 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
8050 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
8051 .word is < -32768 or > 32767. The -J flag causes the error to be
8052 ignored. This is to catch over-sized switches generated by gcc on
8053 systems which don't support the broken .word hack.
8054 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
8055 write.c (fixup_segment): check for signed .word overflow if
8056 WARN_SIGNED_OVERFLOW_WORD.
8058 * write.c (fixup_segment): fixed missing parens in expression
8059 checking for byte or word overflow.

8075 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
8077 * input-scrub.c (input_scrub_push): call input_file_begin, not
8079 messages.c (as_perror): print ": " between the passed in error and
8080 the strerror, like perror does.
8082 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

8085 From Steve Chamberlain:
8086 Makefile.in: Handle m68*-*-coff*.
8087 read.c, read.h: add mult argument to s_space
8089 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
8090 Motorola and MIT syntax; gas can now assemble either type of
8092 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

8098 (write_object_file) call fixup_mdeps
8099 (fixup_segment) set fx_subsy to 0.
8100 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
8102 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
8105 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8107 * Makefile.in (LIBS): Include opcode library.

8132 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
8134 * config/tc-m68k.c (init_table): Now const. Always include 68851
8135 data, so that "bc" is available to 68040 cache instructions.
8136 Added "tt0", "tt1", and 68ec030 variants.
8137 (md_assemble): Complain if 68000 (only) and 68881 are specified.
8138 (enum _register): Added TT0, TT1.
8139 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
8140 line number correctly in "internal error" messages. Don't print
8141 architecture-mismatch message for operand errors.
8143 From Colin Smith (colin@wrs.com):
8144 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

8166 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
8167 has already been formatted (but may still contain %-characters).
8170 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8172 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8173 written with indirection on the last two operands, which can be
8174 either data or address registers. Added a new operand type 'r'
8175 which accepts either register type. Added '(' to notend stuff in
8176 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8448 * Makefile.in: pass down MAKEINFO explicitly on info.
8450 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
8452 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
8454 * flonum-const.c: renamed flonum-konst.c to stop dos name
8457 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
8459 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
8460 tc-m68k.h to te-sun3.h.
8462 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
8464 * configure.in: vxworks68 gets te-sun3.h.
8466 * expr.c: remove limitation that local_labels_dollar or
8467 local_labels_fb must be < 10.
8469 * symbols.c: remove local_labels_dollar, replace with a function
8470 interface for a sparse array. All users adjusted.
8472 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
8474 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8476 * doc/Makefile.in: commented out line for building as-all.texinfo.
8479 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
8481 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
8483 * Makefile.in: added check target.
8485 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8487 * Makefile.in: added tooldir and program_prefix.
8489 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
8491 * write.{c,h} (fix_new): Make these declarations consistent.
8493 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
8495 * Makefile.in (strerror.o): Add rule so that broken Sun make can
8498 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
8500 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
8502 * expr.c (operand): if can't work out what sort of operand it is,
8503 then look through FLT_CHARS for a hint.
8505 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
8507 * Makefile.in, configure.in: removed traces of namesubdir,
8508 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8509 copyrights to '92, changed some from Cygnus to FSF.
8511 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
8512 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8513 copyrights to '92, changed some from Cygnus to FSF.
8515 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8517 * expr.c: If an expression is single comma, then return with
8518 SEG_ABSENT rather than an error - since the sparc front end does
8519 really strange things with things like fbge,a
8521 * as.h: include bfd.h if using many sections
8522 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8523 local labels didn't work.
8524 * listing.c (list_symbol_table): don't core dump when there's no
8526 * write.c, write.h: call fix_new with the right number of args on
8528 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8531 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8533 * app.c: MRI compatibility - allow single quote to start a string.
8534 * as.c: fix typo recently introduced.
8535 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8536 * expr.c: Much rewriting, to accomodate MRI syntax for
8537 expressions. Also easier to read now.
8538 * listing.c: Put back defuns
8539 * read.c: modified to accept MRI syntax, put back listing pseudo
8540 ops so that an assembler built with NO_LISTING ignores list ops
8542 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8543 machine is a SPARC or a 29K.
8544 * config/obj-aout.c: added s_sect pseudo op
8545 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8546 fill in the timestamp.
8547 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8548 anymore, define all the relocs which the tc-<x> bit will use so we
8549 can translate from them to the coff types.
8550 * config/tc-a29k.c: reloc_type isn't ane enum any more
8551 * config/tc-m68k.c: Added NO_RELOC definition.
8553 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8555 * Makefile.in: put header files before C source for TAGS; remove
8556 references to non-existent syscalls.h.
8558 * read.c, write.c subsegs.c: back out the .bss changes.
8560 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8562 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8566 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8568 * symbols.c (local_label_name): symbols now start with ^A.
8570 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8571 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8572 generate these sections. .align: will use NOP_OPCODE or 0
8573 for padding. This is just for being nice to the
8576 * expr.c (operand): changed to generate local label "\001L0"
8577 starting with a ^A so that it is recognized as a local label.
8579 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8581 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8582 i/o opcodes - inb, inw, outb and outw. string manipulation with
8583 att syntax - scmp, slod, smov, ssca, ssto.
8585 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8586 to just after .file .
8588 In obj_crawl_symbol_chain() where it tries to put the external
8589 symbols apart, with the condition:
8590 (!S_IS_DEFINED(symbolP) &&
8591 !S_IS_DEBUG(symbolP) &&
8592 !SF_GET_STATICS(symbolP))
8593 it was moving too many symbols out. So I switch it back to the
8595 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8597 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8598 so that we don't use the F_RELFLG which make the linker complain
8599 that somebody has stripped the relocation info.
8601 Also, the AIX ld program require that the relocation table
8602 is sorted by r_vaddr like the standard ATT assembler does.
8604 [he also changed the sizeof(struct ...)'s into the coff
8605 style FOOSZ macros. I'm not sure this is right, but I can't
8606 remember why. xoxorich.]
8608 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
8610 * Makefile.in, configure.in, doc: use the doc. Build it, install
8613 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
8615 * read.c: white space and comments only.
8617 * configure.in: use the new atof-ns32.c for ns32k.
8619 * write.c: comment change only.
8621 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8622 aren't yet integrated.
8624 * tc-i860.[hc]: blew off the dust. Something must still be done
8625 about conflicting relocation types.
8627 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8630 * tc-i960.c, tc-sparc.c: white space and comments only.
8632 * tc-a29k.h: delete duplicate macro definition.
8634 * new file atof-ns32k.c copied from hack's last unreleased gas.
8636 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8638 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8641 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8642 ChangeLog's prior to this are sketchy at best. I have logs.
8643 They just aren't ChangeLogs.
8650 version-control: never
