13 * configure.in: Set bfd_gas for all sparc targets in one place,
14 instead of separately for each. Correctly handle user-supplied
15 "--enable-bfd-gas" option.
17 * gdbinit.in: Move "break abort" to end, in case gdb complains.
19 * as.h (PRINTF_WHERE_LIKE, PRINT_LIKE) [USE_STDARG, !__GNUC__]:
22 * symbols.c (resolve_symbol_value, case O_symbol): Don't do any
23 processing if add_symbol is undefined or in expr_section.
24 (resolve_symbol_value, case O_add): For symbol plus
25 constant-valued symbol, convert to O_symbol and re-reduce.
26 (S_GET_VALUE): If symbol needs resolving, resolve it.
27 (indent_level): No longer static.
28 (print_symbol_value_1): Don't print frag address if it matches
29 zero_address_frag. Don't print "resolving" if already resolved.
30 Print segment name. Don't call print_expr_1 on an undefined
32 (print_expr_1): Fix whitespace before printing X_add_number.
34 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
35 not symbol_new, for symbols holding expression values.
36 * expr.h (make_expr_symbol): Move declaration here.
37 * write.c (fix_new_exp): Handle O_add by creating an
38 expression-valued symbol, and calling fix_new_exp recursively.
39 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
40 undefined symbol and a constant, fold the constant into the fixup,
41 and refer to the undefined symbol directly. Then process the
42 fixup again from scratch.
43 (write_object_file): Before calling adjust_reloc_syms, make a pass
44 through the symbol list trying to resolve values.
46 * write.c (print_fixup): New routine, for debugging.

54 * Makefile.in (gasp.o): Depends upon config.h.
56 * config/tc-mips.c: Include subsegs.h.
57 (md_apply_fix): If an unconditional b or bal overflows, and we are
58 not assembling PIC code, replace it with a j or jal.
60 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
61 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
63 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
65 * write.c (write_relocs): Add file name and line number to
66 as_fatal calls. Handle bfd_reloc_overflow case specifically when
67 RELOC_EXPANSION_POSSIBLE.
69 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
71 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these
72 here. Use them for deciding which PRINTF*LIKE macro definitions
74 * messages.c: Use them, instead of NO_STDARG, NO_VARARGS.
75 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
76 default definitions matching what we were doing before.
77 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
78 always use the varargs form if not using stdarg. It's safe to
79 always use vfprintf, because libiberty will provide it if the
80 native system doesn't. Also, always make format be const.
81 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
83 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)

87 (macro): Hack the -mips3 overflow tests to not fail when offsetT
90 * symbols.h (copy_symbol_attributes): Declare.
92 Thu Sep 22 21:58:24 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

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

116 * symbols.c (copy_symbol_attributes): New function. Copies BFD
117 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
118 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
119 zero. Don't call obj_frob_forward_symbol.

128 md_estimate_size_before_relax, md_ri_to_chars,
129 md_create_short_jump, md_create_long_jump.
130 (brtab_emit): Use data_section, not SEG_DATA.
132 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
134 * config/vms-conf.h: new file, manually derived from conf.in.
135 * config-gas.com: use it, and eliminate obsolete "host.h".
137 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
139 * config/tc-ppc.c (ppc_current_block): New static variable.
140 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to

145 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
146 from the csect of the enclosing block.
148 * config/tc-mips.c (insns_since_cache_access): Remove.
149 (append_insn): Remove setting of insns_since_cache_access, and
150 special 4600 handling; it turns out not to be required.
152 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
154 * config/tc-mips.c (md_shortopts): Remove E.
155 (md_longopts): Add EB and EL.
156 (md_parse_option): Handle -EB and -EL as separate options, rather
157 than as a single -E option with an argument.
159 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
161 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
162 involving global symbols too.
164 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
166 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
168 * configure.in: Test for remove, not delete. Fix cross-assembler
170 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
173 * read.c (pseudo_set, case O_symbol): If
174 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.

178 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
180 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
181 many others): new macros; values obtained from "DSTRECRDS.SDL".
182 * config/obj-vms.h (various): use them.
183 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
184 representation (only enum bitfields can avoid being bitstrings).
185 (bitfield_suffix, setup_basic_type): new routines.
186 (VMS_typedef_parse): use them. Now recognize bitfields of all
187 integral types, not just type `int'. Caveat: the representation
188 used for bitfields still does not work for objects placed in
189 registers, and gcc's optimizer sometimes puts small structs there.
191 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
193 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
195 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
196 (tc_frob_label): define this to call vms_check_for_special_label,
197 and declare the latter.
198 * config/obj-vms.c (vax_g_doubles): declare this file-scope
200 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
201 (vms_check_for_special_label): new routine (tc_frob_label).
202 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
203 and `gcc2_compiled.' labels; they won't reach here any more.
204 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
205 double', use `vax_g_doubles' flag to select type of double.
206 (VMS_write_object_file) [traceback setup]: don't pass symbols
207 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
208 and TBT_Routine_End functions.
210 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
212 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
213 S_GET_VALUE() to avoid many repeated function calls.
214 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
215 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
216 gets requested. [All the HACK_DEC_C_STARTUP code appears to
217 be obsolete; gcc does it automatically for vms target. It's
218 also misnamed, because it is for the "VAX C" run-time library,
219 not the newer "DEC C" one which has much different startup code.]
220 {various}: use `S_SET_xxx(symbol,new_value)' rather than
221 `S_GET_xxx(symbol) = new_value'.
223 Mon Sep 19 12:05:03 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
225 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,

230 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
232 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
234 * expr.c (expr): Don't reduce the difference of two symbols in the
235 same frag if the symbols are not in normal sections.
237 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
238 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
239 (obj_attach_unwind_info): Do not define. Not needed anymore.
240 * config/tc-hppa.c: Delete whitespace at EOL.
241 (struct hppa_fix_struct): Delete fx_unwind field and all references.
242 (fix_new_hppa): Last arg is now a pointer to an int. Do not
243 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
244 fixups, store 32bits of unwind information in the fx_addnumber
246 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
247 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
248 pointer to 32 bits of unwind info.
249 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
250 pointer to the dummy symbol; set the addend field to fx_addnumber.
251 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
252 rather than &bfd_XXX_section.
254 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
256 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
257 value by one; discard adjustments previously being made. From
260 VMS- and Vax-related changes from Pat Rankin:
261 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
262 * vmsconf.sh: no longer have make-gas.com echo text about needing
263 to modify the gcc-vms driver when intending to use with gcc 1.x.
264 * as.c (parse_options): suppress 'v' from std_short_options and
265 eliminate VMS-specific conditional initialization;
266 [default case]: check for '-v' if md_parse_options doesn't recognize
268 [default case, #if VMS]: check for filename argument when '-v' seen;
270 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
271 for O_big literal operands (double floats and long long ints);
272 [VMS, md_shortopts]: add second colon after 'v';
273 (md_parse_options) [VMS, case 'v']: check for argument, so
274 caller can handle `-v' w/o arg.

326 * gdbinit.in: New file, created from old .gdbinit.
328 * aclocal.m4 (GAS_GDBINIT): Deleted.
329 * configure.in: Don't use it. Instead, generate .gdbinit from
330 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
331 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
332 to ensure that older versions of autoconf aren't used.
333 * Makefile.in: Added @configure_input@ line.

424 * read.c (read_a_source_file): The second argument to as_where is
425 unsigned int *, not int *.
427 Thu Sep 8 17:18:24 1994 Kung Hsu (kung@mexican.cygnus.com)

465 * Makefile.in (CC_FOR_TARGET, NM_FOR_TARGET, OBJDUMP_FOR_TARGET,
466 install, uninstall): Don't use "brokensed" hack any more, the new

1898 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
1899 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
1900 and -many (all architectures).
1902 Sun Mar 27 14:04:19 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

1911 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
1913 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
1914 branch with an instruction that uses $at, in case the branch is
1916 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
1917 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
1918 to make it pcrel_offset.
1919 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
1920 reloc->address; another gruesome hack to get gas reloc handling to
1923 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1925 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
1928 (emit_insn): New function.
1929 (md_assemble): Call it.
1930 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
1932 (lituse_pending): New variable. Set by anything that generates a
1933 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
1934 tested by code that might want to emit a LITUSE reloc.
1935 (emit_unaligned_io): New function. Currently calls md_assemble,
1936 but it should eventually be converted to generate the insn itself
1937 and call emit_insn directly.
1938 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
1939 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
1940 emit_bis_r): Likewise.

1944 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
1945 unaligned memory access macros.
1946 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
1947 the value can't be resolved.
1949 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1951 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
1952 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
1953 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
1955 (mips_force_relocation): New function.
1956 (md_apply_fix): Set fixP->fx_done appropriately.
1957 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

1965 * config/tc-mips.c (enum mips_pic_level): New enum.
1966 (mips_pic): Change from int to enum mips_pic_level. Change all
1967 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
1968 (load_address): Handle EMBEDDED_PIC.
1969 (macro): Handle EMBEDDED_PIC in all PIC cases.
1970 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
1971 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
1972 -non_shared to use NO_PIC (this is how the Irix 5 assembler
1973 works). Do not permit -G with SVR4_PIC.
1974 (s_abicalls): Warn if -G was used, and force -G 0.
1975 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
1976 anything but a.out, not just for ELF. For ECOFF, don't generate a
1977 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
1979 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
1981 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1983 * config/tc-hppa.c (create_new_space): Use ints, not chars as
1984 parameters to avoid losing when compiling with HP CC.
1985 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
1987 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1989 * Makefile.in (config-stamp): If `defs' is defined, emit a
1990 preprocessor directive to create a macro named by this value into
1991 config.new; don't explicitly go for BFD_ASSEMBLER.
1992 * configure.in: Define `defs', not `BFDDEF'. Set it to
1993 MANY_SEGMENTS for any obj-coffbfd target.
1994 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
1995 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
1997 (LOCAL_LOADLIBES): Deleted.
1998 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
1999 * config/m88kcoff.mt (TDEFINES): Ditto.

2025 bfd_set_symtab is called.
2026 (dump_section_relocs): Note whether a symbol is a section symbol
2028 (adjust_reloc_syms): For now, always supply an absolute symbol for
2029 fixups without symbols but not yet `done'. Use section_symbol to
2030 get the symbol, instead of going directly for abs_symbol.
2031 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2032 reloc is not a section symbol and is not in the symbol table.
2033 (set_symtab): New function, broken out from write_object_file.
2034 Counts symbol table instead of relying on an earlier count.
2035 (write_object_file): Call set_symtab, but do it after potentially
2036 invoking the *_frob_file macros. Don't bother counting symbols.
2037 Call symbol_remove, instead of expanding it in place. Moved the
2038 conditionalized `object_file_size' declaration down to
2039 conditionalized block where it's used. When using the absolute
2040 symbol for a fixup without a symbol, set sy_used_in_reloc.
2041 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2042 the correct symbol for the absolute section.
2044 * subsegs.c (section_symbol): Use symbol_new instead of
2045 symbol_make, since we may want it to go into the symbol table.
2046 Make the new symbol have internal linkage. If
2047 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2048 symbol with the newly created GAS symbol.
2049 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2050 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2057 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2058 (sparc_ip, label "immediate"): Reject constants for pcrel
2059 instructions only if the relocation type indicates a "call"
2060 instruction and the offset is within range of a "jmpl %g0". If
2061 it's not in range, use the absolute section symbol plus an offset.
2062 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2064 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2066 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2069 * configure.in: Eliminated all targets using obj-coff but not
2070 defining BFD_ASSEMBLER; I think all such targets that are
2071 supported will be matched by real CPU-OS combinations earlier in
2073 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2074 some comments about the dpx2 configuration, but left it disabled,
2075 since it couldn't be reached before.
2076 (target a29k-amd-ebmonold): Deleted.
2078 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2086 the 'j' operand if there are no further alternatives for this
2089 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2090 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2091 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2093 * config/tc-mips.c (mips_align): Take new argument, label, and use
2094 it instead of global insn_label.
2095 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2096 call to mips_emit_delay and pass it to mips_align.
2098 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2100 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.

2111 S_IS_EXTERNAL when deciding whether to discard a symbol.
2113 * config-gas.com: Scan Makefile.in, not version.c, for current
2114 version number. Delete all versions of temp files when finished
2115 with them. Create config.h.
2117 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2118 values to reduce number of lookups with S_GET_VALUE. Skip debug
2119 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2120 holger@botbso.rhein-main.de.)
2121 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2122 field. (Also from Holger Teutsch.) Watch for a would-be register
2123 mask that spans frags.
2125 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2126 this_base, not line_base. (Patch from Andreas Arens,
2127 ari@obelix.av.rwth-aachen.de.)
2129 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2130 look local if they're exported or undefined. Used to be done for
2133 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2134 Get it from the looked-up symbol, instead of using the string from
2135 the input stream, which is no longer null-terminated.
2136 (LEX_PCT): New macro, defaults to 0.
2137 (lex_type): Use it for `%'.
2139 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

2189 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2190 0xffff for 'j' to be compatible with MIPS assembler. These

4262 * configure.in: Set bfd_gas for all sparc targets. Added facility
4263 for keeping or rejecting configurations still under development;
4264 default is to assume production environment, and reject configs
4265 still being worked on. Mark Elf configurations (except sparc and
4266 i386) as developmental. Deleted cases matching some generic names
4267 in favor of more specific names. (E.g., when we get Alpha

4293 into a few places. Make all functions and variables which
4294 are only used within tc-hppa.c static. PARAMize all functions.
4295 Add comments to functions. Delete unused functions, variables,
4296 #defines, etc. Delete unused members within structures. Delete
4297 ldil;ble hacks -- it is believed they were installed to work
4298 around old gas bugs. Avoid using mixed case for local
4299 functions, variables, and structures. Fix formatting problems
4300 not found by GNU-indent. Add FIXME notices for things which
4301 should be worked on the near future. Delete lots of old
4302 useless (1.36 PA-SOM) code.

4319 * config/tc-hppa.c: Likewise.
4321 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
4322 of elf32_symbol_type.
4323 (pa_export_args): Likewise.
4324 (elf_hppa_final_processing): Likewise.

4331 a multiple of the section alignment rather than always a
4334 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4335 bits are zero (eg they specify no relocations), then do not even
4336 bother adding their entries to thesymextn section.

4381 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4383 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4384 ELF, since the ELF object format does not have these type of
4385 relocations. Change the abort into as as_bad and return
4386 BFD_RELOC_NONE to silence compiler warnings.
4387 (md_assemble): Keep track of the instruction size. Allow white

6773 a29k .bss section; the mondfe program doesn't like it.

6794 source directory, if that's not the current directory.
6796 * configure.in (per-host): Accept MIPS host with BSD version

6822 avoid some redefinition complaints on some systems.
6823 (const, volatile): Don't need these conditionally defined if we
6824 use CONST and VOLATILE from ansidecl.h.
6825 (seg_name): Use CONST, not const.
6827 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
6829 * config/tc-mips.c: Reindented to GNU standards.
6831 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
6833 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
6834 (fixup_segment): Add a29k special case; the linker is not prepared
6835 to see a segment offset here.
6837 * app.c (do_scrub_next_char): Added new state, 10, modifying state

6840 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
6842 * Makefile.in: add dvi target; as-$(config).texinfo might live in
6843 srcdir, might be in objdir.
6845 * doc/Makefile.in: dvi depends on as.dvi

6873 dropping a space immediately following an identifier.
6874 * expr.c, write.c: Rewrote assert expressions to not use multiple
6875 lines; I don't think that can be done portably.
6876 * config/tc-mips.c (macro): Use $AT if target register is zero in
6877 load instruction, which it can be for a floating point load.

6890 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
6891 z8k-opc.h, not z8k.h.
6893 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
6896 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

6947 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.

6951 prototypes for all static functions. Moved existing minimal
6952 debugging format support info #ifndef OBJ_ECOFF blocks.

7001 * make-gas.com: Find obstack.obj if it's not in the current
7003 * read.c (s_ignore): Don't declare is_end_of_line. It's
7004 redundant, and triggers a VMS gcc compiler bug.
7006 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
7007 current segment as an argument. (Ignored in all cases but VMS.)

7355 (which will be declared in obj-vms.h).
7356 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7357 Fix arguments to VMS_write_object_file.
7358 * config-gas.com: New file. Script for VMS systems to set up the

7389 SEG_DATA or SEG_E1 if needed.
7390 (s_lcomm): Likewise with bss_section.
7391 (s_fill): Use memset, not bzero.

7418 mapping to segT enum values.
7419 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7420 if these are used or defined, if BFD_ASSEMBLER.
7421 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7422 subseg_new split into two functions.
7423 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7425 * as.h (volatile): Don't define if already defined.
7426 (had_errors, had_warnings): Provide prototypes for ANSI C even if

7466 (fill_section): Always set s_vaddr here, removing
7467 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7468 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7469 Set STYP_INFO for .comment.

7473 H_{SET,GET}_* macros.
7474 (do_linenos_for): Set lineno size in object_headers.
7475 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7476 set s_vaddr here. If string_byte_count remains 4, set it back to
7477 0, and only write strings out if there are some. Call
7478 fill_section before do_relocs_for and do_linenos_for.
7479 (obj_coff_section): Handle optional quoted second argument giving
7480 section characteristics.
7481 (obj_coff_bss): Added to handle .bss.

7503 (symbol_chars): Now const.
7505 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"

7508 * config/obj-coff.h: Don't use #elif.
7510 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't

7542 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7543 definitions, and don't merge tags with non-tags. Check for .bf
7544 rather than just checking whether the second character is b and
7545 the third character is f.
7546 (obj_coff_val): gcc can generate values which we don't handle
7547 correctly; discard information for now, since it only affects the
7548 debugging information.

7550 (yank_symbols): Don't merge labels.
7551 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7697 could be doing emulation.
7699 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7702 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

7811 * tc-z8k.c: lots of bug fixes
7813 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7815 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7816 #elif, since it is not supported by old compilers.
7817 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7818 couple of expressions in tc-m68k.c.
7820 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

7846 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
7848 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7849 sections starting from zero, rather than making them consecutive.
7850 This makes subsequent reloc calculations easier, esp if the object
7851 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7852 allocate lcomm in .data rather than in .bss. It seems that some
7853 tools can't cope with a non-zero sized bss before linkage.

7876 * Makefile.in (install): if $(tooldir) exists, install as in
7879 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
7881 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
7882 .word is < -32768 or > 32767. The -J flag causes the error to be
7883 ignored. This is to catch over-sized switches generated by gcc on
7884 systems which don't support the broken .word hack.
7885 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
7886 write.c (fixup_segment): check for signed .word overflow if
7887 WARN_SIGNED_OVERFLOW_WORD.

7906 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
7908 * input-scrub.c (input_scrub_push): call input_file_begin, not
7910 messages.c (as_perror): print ": " between the passed in error and
7911 the strerror, like perror does.
7913 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
7915 * Makefile.in: use gas_target instead of modifying target_cpu.
7916 From Steve Chamberlain:
7917 Makefile.in: Handle m68*-*-coff*.

7920 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
7921 Motorola and MIT syntax; gas can now assemble either type of

7929 (write_object_file) call fixup_mdeps
7930 (fixup_segment) set fx_subsy to 0.
7931 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
7933 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
7936 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7938 * Makefile.in (LIBS): Include opcode library.

7965 * config/tc-m68k.c (init_table): Now const. Always include 68851
7966 data, so that "bc" is available to 68040 cache instructions.
7967 Added "tt0", "tt1", and 68ec030 variants.
7968 (md_assemble): Complain if 68000 (only) and 68881 are specified.
7969 (enum _register): Added TT0, TT1.

8001 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
8003 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
8004 written with indirection on the last two operands, which can be
8005 either data or address registers. Added a new operand type 'r'
8006 which accepts either register type. Added '(' to notend stuff in
8007 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8119 characteristics have been), default to 68020. Don't need extra
8120 quotes around error string.

8202 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
8204 * write.c (write_object_file): keep the fix_tail clean, which
8205 fixes a bug in -R where relocations were being lost.

8253 * write.c (write_object_file): For b.out format, round up section
8254 start addresses to match required alignment.
8256 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8258 * Makefile.in (install): Install into $(tooldir)/bin, since that's
8259 where gcc looks for it.
8261 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
8263 * Makefile.in: Changed some lines to be less confusing for some

8336 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
8338 * Makefile.in, configure.in: removed traces of namesubdir,

8342 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
8343 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8344 copyrights to '92, changed some from Cygnus to FSF.
8346 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8348 * expr.c: If an expression is single comma, then return with
8349 SEG_ABSENT rather than an error - since the sparc front end does
8350 really strange things with things like fbge,a
8352 * as.h: include bfd.h if using many sections
8353 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8354 local labels didn't work.
8355 * listing.c (list_symbol_table): don't core dump when there's no
8357 * write.c, write.h: call fix_new with the right number of args on
8359 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8362 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8364 * app.c: MRI compatibility - allow single quote to start a string.
8365 * as.c: fix typo recently introduced.
8366 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8367 * expr.c: Much rewriting, to accomodate MRI syntax for
8368 expressions. Also easier to read now.
8369 * listing.c: Put back defuns
8370 * read.c: modified to accept MRI syntax, put back listing pseudo
8371 ops so that an assembler built with NO_LISTING ignores list ops
8373 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8374 machine is a SPARC or a 29K.
8375 * config/obj-aout.c: added s_sect pseudo op
8376 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8377 fill in the timestamp.
8378 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8379 anymore, define all the relocs which the tc-<x> bit will use so we
8380 can translate from them to the coff types.
8381 * config/tc-a29k.c: reloc_type isn't ane enum any more
8382 * config/tc-m68k.c: Added NO_RELOC definition.
8384 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8386 * Makefile.in: put header files before C source for TAGS; remove
8387 references to non-existent syscalls.h.
8389 * read.c, write.c subsegs.c: back out the .bss changes.
8391 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8393 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8397 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8399 * symbols.c (local_label_name): symbols now start with ^A.
8401 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8402 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8403 generate these sections. .align: will use NOP_OPCODE or 0
8404 for padding. This is just for being nice to the
8407 * expr.c (operand): changed to generate local label "\001L0"
8408 starting with a ^A so that it is recognized as a local label.
8410 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8412 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8413 i/o opcodes - inb, inw, outb and outw. string manipulation with
8414 att syntax - scmp, slod, smov, ssca, ssto.
8416 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8417 to just after .file .
8419 In obj_crawl_symbol_chain() where it tries to put the external
8420 symbols apart, with the condition:
8421 (!S_IS_DEFINED(symbolP) &&
8422 !S_IS_DEBUG(symbolP) &&
8423 !SF_GET_STATICS(symbolP))
8424 it was moving too many symbols out. So I switch it back to the
8426 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8428 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8429 so that we don't use the F_RELFLG which make the linker complain
8430 that somebody has stripped the relocation info.
8432 Also, the AIX ld program require that the relocation table
8433 is sorted by r_vaddr like the standard ATT assembler does.
8435 [he also changed the sizeof(struct ...)'s into the coff
8436 style FOOSZ macros. I'm not sure this is right, but I can't
8437 remember why. xoxorich.]
8439 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
8441 * Makefile.in, configure.in, doc: use the doc. Build it, install

8446 * read.c: white space and comments only.
8448 * configure.in: use the new atof-ns32.c for ns32k.
8450 * write.c: comment change only.
8452 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8453 aren't yet integrated.
8455 * tc-i860.[hc]: blew off the dust. Something must still be done
8456 about conflicting relocation types.
8458 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8461 * tc-i960.c, tc-sparc.c: white space and comments only.
8463 * tc-a29k.h: delete duplicate macro definition.
