21 * config/obj-aout.c (obj_aout_frob_symbol): If N_EXT is set for an
22 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
24 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
25 branch with an instruction that uses $at, in case the branch is
27 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
28 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
29 to make it pcrel_offset.
30 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
31 reloc->address; another gruesome hack to get gas reloc handling to
34 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
36 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
39 (emit_insn): New function.
40 (md_assemble): Call it.
41 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
43 (lituse_pending): New variable. Set by anything that generates a
44 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
45 tested by code that might want to emit a LITUSE reloc.
46 (emit_unaligned_io): New function. Currently calls md_assemble,
47 but it should eventually be converted to generate the insn itself
48 and call emit_insn directly.
49 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
50 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
51 emit_bis_r): Likewise.

62 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
63 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

76 * config/tc-mips.c (enum mips_pic_level): New enum.
77 (mips_pic): Change from int to enum mips_pic_level. Change all
78 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
79 (load_address): Handle EMBEDDED_PIC.
80 (macro): Handle EMBEDDED_PIC in all PIC cases.
81 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
82 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
83 -non_shared to use NO_PIC (this is how the Irix 5 assembler
84 works). Do not permit -G with SVR4_PIC.
85 (s_abicalls): Warn if -G was used, and force -G 0.
86 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
87 anything but a.out, not just for ELF. For ECOFF, don't generate a
88 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
90 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
92 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
94 * config/tc-hppa.c (create_new_space): Use ints, not chars as
95 parameters to avoid losing when compiling with HP CC.

98 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
100 * Makefile.in (config-stamp): If `defs' is defined, emit a
101 preprocessor directive to create a macro named by this value into
102 config.new; don't explicitly go for BFD_ASSEMBLER.
103 * configure.in: Define `defs', not `BFDDEF'. Set it to
104 MANY_SEGMENTS for any obj-coffbfd target.
105 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
106 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
108 (LOCAL_LOADLIBES): Deleted.
109 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
110 * config/m88kcoff.mt (TDEFINES): Ditto.

136 bfd_set_symtab is called.
137 (dump_section_relocs): Note whether a symbol is a section symbol
139 (adjust_reloc_syms): For now, always supply an absolute symbol for
140 fixups without symbols but not yet `done'. Use section_symbol to
141 get the symbol, instead of going directly for abs_symbol.
142 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
143 reloc is not a section symbol and is not in the symbol table.
144 (set_symtab): New function, broken out from write_object_file.
145 Counts symbol table instead of relying on an earlier count.
146 (write_object_file): Call set_symtab, but do it after potentially
147 invoking the *_frob_file macros. Don't bother counting symbols.
148 Call symbol_remove, instead of expanding it in place. Moved the
149 conditionalized `object_file_size' declaration down to
150 conditionalized block where it's used. When using the absolute
151 symbol for a fixup without a symbol, set sy_used_in_reloc.
152 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
153 the correct symbol for the absolute section.
155 * subsegs.c (section_symbol): Use symbol_new instead of
156 symbol_make, since we may want it to go into the symbol table.
157 Make the new symbol have internal linkage. If
158 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
159 symbol with the newly created GAS symbol.
160 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
161 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

166 (in_signed_range): New function.
168 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
169 (sparc_ip, label "immediate"): Reject constants for pcrel
170 instructions only if the relocation type indicates a "call"
171 instruction and the offset is within range of a "jmpl %g0". If
172 it's not in range, use the absolute section symbol plus an offset.
173 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
175 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
177 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
180 * configure.in: Eliminated all targets using obj-coff but not
181 defining BFD_ASSEMBLER; I think all such targets that are
182 supported will be matched by real CPU-OS combinations earlier in
184 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
185 some comments about the dpx2 configuration, but left it disabled,
186 since it couldn't be reached before.
187 (target a29k-amd-ebmonold): Deleted.
189 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

197 the 'j' operand if there are no further alternatives for this
200 * config/obj-coffbfd.c (adjust_stab_section): Initialize
201 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
202 is not SEG_UNKNOWN rather than checking whether it is >= 0.
204 * config/tc-mips.c (mips_align): Take new argument, label, and use
205 it instead of global insn_label.
206 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
207 call to mips_emit_delay and pass it to mips_align.
209 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
211 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
213 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
214 argument to a .callinfo directive. Don't loop forever on errors.
216 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
217 use pre-defined registers as arguments.
219 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
221 * write.c (write_object_file): Check both S_IS_LOCAL and
222 S_IS_EXTERNAL when deciding whether to discard a symbol.
224 * config-gas.com: Scan Makefile.in, not version.c, for current
225 version number. Delete all versions of temp files when finished
226 with them. Create config.h.
228 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
229 values to reduce number of lookups with S_GET_VALUE. Skip debug
230 symbols to avoid "a really nasty bug". (From Holger Teutsch,
231 holger@botbso.rhein-main.de.)
232 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
233 field. (Also from Holger Teutsch.) Watch for a would-be register
234 mask that spans frags.
236 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
237 this_base, not line_base. (Patch from Andreas Arens,
238 ari@obelix.av.rwth-aachen.de.)
240 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
241 look local if they're exported or undefined. Used to be done for
244 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
245 Get it from the looked-up symbol, instead of using the string from
246 the input stream, which is no longer null-terminated.

248 (lex_type): Use it for `%'.
250 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
251 (vip_op): Now static, and returns void. Callers changed. Added

2371 support, we'll still only support VMS for Vax.)
2373 * config/tc-sparc.h (md_end): New macro.
2374 * config/tc-sparc.c (md_end): Function deleted.
2375 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

2385 against placing additional object-file dependent code here. Warn
2386 against contaminating all of GAS with the internals of tc-hppa.c
2387 through inclusion of tc-hppa.h. Delete all forward declarations
2388 for functions only used within tc-hppa.c, likewise for structures,
2389 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2390 conditional code in a few small places.
2392 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2393 structures, global variables, forward declarations together.
2394 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
2395 conditional code -- try to group conditional code together
2396 into a few places. Make all functions and variables which
2397 are only used within tc-hppa.c static. PARAMize all functions.
2398 Add comments to functions. Delete unused functions, variables,
2399 #defines, etc. Delete unused members within structures. Delete
2400 ldil;ble hacks -- it is believed they were installed to work
2401 around old gas bugs. Avoid using mixed case for local
2402 functions, variables, and structures. Fix formatting problems
2403 not found by GNU-indent. Add FIXME notices for things which
2404 should be worked on the near future. Delete lots of old
2405 useless (1.36 PA-SOM) code.

2417 which do not involve function symbols.
2419 * config/tc-hppa.h: Reindent with GNU-indent. Delete references

2425 of elf32_symbol_type.
2426 (pa_export_args): Likewise.
2427 (elf_hppa_final_processing): Likewise.

2433 * config/tc-hppa.c: (md_section_align): Align all sections to
2434 a multiple of the section alignment rather than always a
2437 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2480 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2481 ELF, since the ELF object format does not have these type of
2482 relocations. Change the abort into as as_bad and return
2483 BFD_RELOC_NONE to silence compiler warnings.
2484 (md_assemble): Keep track of the instruction size. Allow white

3548 * Extensive changes to permit symbols to contain any expression
3549 type and to delay the computation of the expression until the
3550 value is actually needed. This permits setting symbols to values
3551 calculated based on object code size. Expressions were changed to
3552 no longer be in a section, to stop the overloading of segment and
3553 expression type that previously occurred.
3555 * as.c (big_section, pass1_section, diff_section, absent_section):

4847 source directory, if that's not the current directory.
4849 * configure.in (per-host): Accept MIPS host with BSD version

4871 process relocs if there aren't any relocs to process. Avoids
4872 malloc/free bug on SCO too.

4875 avoid some redefinition complaints on some systems.
4876 (const, volatile): Don't need these conditionally defined if we
4877 use CONST and VOLATILE from ansidecl.h.
4878 (seg_name): Use CONST, not const.
4880 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4882 * config/tc-mips.c: Reindented to GNU standards.

4886 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4887 (fixup_segment): Add a29k special case; the linker is not prepared
4888 to see a segment offset here.
4890 * app.c (do_scrub_next_char): Added new state, 10, modifying state

4893 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4895 * Makefile.in: add dvi target; as-$(config).texinfo might live in
4896 srcdir, might be in objdir.

4911 bignums, but don't emit error message.
4913 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
4915 * Makefile.in (targ-cpu.o): Depend on config.h.
4917 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4919 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4920 dropping a space immediately following an identifier.
4921 * expr.c, write.c: Rewrote assert expressions to not use multiple
4922 lines; I don't think that can be done portably.
4923 * config/tc-mips.c (macro): Use $AT if target register is zero in
4924 load instruction, which it can be for a floating point load.
4926 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)
4928 * write.c (write_contents): Compute the relocs before writing out

4940 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
4943 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

4947 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4949 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4950 to be on a single line.
4952 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4954 * Makefile.in (config.h): Create file, writing out definitions of

4997 * config/tc-mips.c: Rearranged for ECOFF support. Added
4998 prototypes for all static functions. Moved existing minimal
4999 debugging format support info #ifndef OBJ_ECOFF blocks.

5048 * make-gas.com: Find obstack.obj if it's not in the current
5050 * read.c (s_ignore): Don't declare is_end_of_line. It's
5051 redundant, and triggers a VMS gcc compiler bug.
5053 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5054 current segment as an argument. (Ignored in all cases but VMS.)
5055 All callers and definitions changed.

5073 argument to s_ignore. Put "#if 0" around unused code.
5074 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
5075 Call elf_xstabs for .stabs and .xstabs operators.

5352 md_relax_table): Use default zero initialization.
5353 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5354 latter, instead of selecting with preprocessor conditionals.
5356 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5358 * configure.in: recognise all sparclite variants
5360 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

5368 * expr.c (operand): If character other than comma or newline is a
5369 logical end-of-line character, use the newline case.
5370 From Eric Youngdale:
5371 (operand): Set X_add_number field for floating-point numbers.
5372 (operand): Treat zero byte as end-of-operand.
5374 * configure.in (per-target): Look for with_bfd_assembler option.
5375 For now, only accept "no", until the merge is done.
5377 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5378 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5384 * expr.c: Add "const" modifier to hex_value.
5385 * symbols.c: Finish conversion to S_* macros in the VMS only
5386 parts of the program. Add "const" modifier to
5387 md_[long,short]_jump_size. Remove declaration of const_flag
5388 (which will be declared in obj-vms.h).
5389 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5390 Fix arguments to VMS_write_object_file.
5391 * config-gas.com: New file. Script for VMS systems to set up the
5392 configuration to build gas for VMS, and create config.status.
5393 * make-gas.com: Redone to work with new scheme.
5394 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5396 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5397 will swap bytes if needed on a big endian system. Use throughout
5399 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5400 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5401 types of malformed stabs. Change parsing algorithm so that we are
5402 more certain of having all of the information that we need on hand.
5403 * obj-vms.c (final_forward_reference): New function, used to help
5404 resolve the data types of as many struct elements as possible
5405 when some part of the struct is not fully defined by the compiler.

5408 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5409 as symbols as well in the object file. Look for external functions
5410 that start with "__vt.", and turn them into variables, since the
5411 g++ compiler is incapable of doing this.
5412 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5414 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5415 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5416 have the name of the source file yet.
5417 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5419 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5421 * read.c (s_data): Always use "data_section", since it'll map to
5422 SEG_DATA or SEG_E1 if needed.
5423 (s_lcomm): Likewise with bss_section.
5424 (s_fill): Use memset, not bzero.
5426 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5448 (big_section, reg_section, pass1_section, diff_section,
5449 absent_section, text_section, data_section, bss_section): If
5450 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5451 mapping to segT enum values.
5452 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5453 if these are used or defined, if BFD_ASSEMBLER.
5454 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5455 subseg_new split into two functions.
5456 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5458 * as.h (volatile): Don't define if already defined.
5459 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5461 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5462 declare with format attribute for -Wformat checking.
5464 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5466 * app.c, config/tc-*.c: Don't include read.h, since it is already
5469 * These are based on patches from Minh Tran-le
5470 <mtranle@paris.intellicorp.com>.
5471 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5472 obj_format coffbfd and gas_target i386coff for target.
5473 (i[34]86-*-isc*): New host (uses sysv).
5474 * config/i386aix.mt: Removed (no longer used).
5475 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5477 (LDFLAGS): Added, defined as -shlib.
5478 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5479 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5480 (DOT_LABEL_PREFIX): Define.
5481 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5482 name rather than L0\001.
5483 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5485 * symbols.c, symbols.h (local_bss_counter): Removed.
5486 * write.c (write_object_file): bss no longer uses

5494 (size_section): Restored sanity check.
5495 (do_relocs_for): Base section address on s_paddr rather than
5496 computing it. Adjust a29k R_IHIHALF special case to account for
5497 section paddr (used to require paddr to be zero). If there are no
5498 reclos, set s_relptr to 0. Set relocation size in object_headers.
5499 (fill_section): Always set s_vaddr here, removing
5500 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5501 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5502 Set STYP_INFO for .comment.
5503 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5504 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
5505 (crawl_symbols): Handle 8 character section name correctly. Use
5506 H_{SET,GET}_* macros.
5507 (do_linenos_for): Set lineno size in object_headers.
5508 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5509 set s_vaddr here. If string_byte_count remains 4, set it back to
5510 0, and only write strings out if there are some. Call
5511 fill_section before do_relocs_for and do_linenos_for.
5512 (obj_coff_section): Handle optional quoted second argument giving
5513 section characteristics.
5514 (obj_coff_bss): Added to handle .bss.
5515 (obj_coff_ident): Added to handle .ident (puts string in .comment

5535 (do_scrub_next_char): For \", return " not '.
5536 (symbol_chars): Now const.
5538 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5539 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5541 * config/obj-coff.h: Don't use #elif.
5543 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5544 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5546 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5548 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5568 SEG_BSS, fill with NOP_OPCODE.
5569 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
5570 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5571 using ZERO_BASED_SEGMENTS.
5572 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5573 never set segment address for SEG_E2 (.bss) and don't write out
5574 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5575 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5576 definitions, and don't merge tags with non-tags. Check for .bf
5577 rather than just checking whether the second character is b and
5578 the third character is f.
5579 (obj_coff_val): gcc can generate values which we don't handle
5580 correctly; discard information for now, since it only affects the
5581 debugging information.
5582 (tag_find_or_name): Don't insert tags in the symbol table.
5583 (yank_symbols): Don't merge labels.
5584 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5603 * config/tc-i386.c (md_pseudo_table): For 386bsd and linux, do
5604 power-of-two alignment for .align.
5606 * as.h: If BROKEN_ASSERT, just redefine `assert' to be trivial,
5607 and leave everything else alone.
5609 Fri Dec 4 16:58:42 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

5730 could be doing emulation.
5732 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5735 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5764 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5766 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5767 constant will not fit in an immediate field.
5768 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5805 * Support for i386-sysv.
5806 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5846 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5848 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5849 #elif, since it is not supported by old compilers.
5850 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5851 couple of expressions in tc-m68k.c.
5853 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5855 * read.c (cons): If NO_RELOC is defined, use it.
5857 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5859 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5861 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5862 local labels to start with a .) and set REGISTER_PREFIX to %.
5863 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5865 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5879 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5881 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5882 sections starting from zero, rather than making them consecutive.
5883 This makes subsequent reloc calculations easier, esp if the object
5884 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5885 allocate lcomm in .data rather than in .bss. It seems that some
5886 tools can't cope with a non-zero sized bss before linkage.
5888 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5890 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5909 * Makefile.in (install): if $(tooldir) exists, install as in
5912 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5914 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5915 .word is < -32768 or > 32767. The -J flag causes the error to be
5916 ignored. This is to catch over-sized switches generated by gcc on
5917 systems which don't support the broken .word hack.
5918 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5919 write.c (fixup_segment): check for signed .word overflow if
5920 WARN_SIGNED_OVERFLOW_WORD.
5922 * write.c (fixup_segment): fixed missing parens in expression
5923 checking for byte or word overflow.

5939 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5941 * input-scrub.c (input_scrub_push): call input_file_begin, not
5943 messages.c (as_perror): print ": " between the passed in error and
5944 the strerror, like perror does.

5949 From Steve Chamberlain:
5950 Makefile.in: Handle m68*-*-coff*.
5951 read.c, read.h: add mult argument to s_space
5953 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5954 Motorola and MIT syntax; gas can now assemble either type of
5956 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5963 (fixup_segment) set fx_subsy to 0.
5964 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5966 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5969 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5971 * Makefile.in (LIBS): Include opcode library.
5973 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

5993 tc-i960.c (md_ri_to_chars): Always output bout object file in
5994 little endian byte order (used to use endianness of host).
5996 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5998 * config/tc-m68k.c (init_table): Now const. Always include 68851
5999 data, so that "bc" is available to 68040 cache instructions.
6000 Added "tt0", "tt1", and 68ec030 variants.
6001 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6002 (enum _register): Added TT0, TT1.
6003 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6004 line number correctly in "internal error" messages. Don't print
6005 architecture-mismatch message for operand errors.
6007 From Colin Smith (colin@wrs.com):
6008 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6009 than install_operand.

6013 * listing.c (buffer_line): rewind to the start of include
6014 files, they might be included twice.

6025 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6026 so that we can assemble hand-written libgcc code.

6030 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6031 has already been formatted (but may still contain %-characters).
6034 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6036 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6037 written with indirection on the last two operands, which can be
6038 either data or address registers. Added a new operand type 'r'
6039 which accepts either register type. Added '(' to notend stuff in
6040 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6042 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)

6056 (relax_align): If linkrelax, provide extra padding.
6058 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6059 their not having symbols associated.
6061 * tc-i960.c (norelax, instrument_branches): Default initializer is
6063 (linkrelax): Delete variable definition.

6087 being used with args swapped, causing occasional lossage when
6088 refilling buffers after an include file.

6092 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
6093 version. Discard bogus DONTDEF version.

6096 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
6098 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
6099 selected architecture, print a message saying so and listing what

6150 processor/opcode mismatch, so reword the error message.
6151 (md_assemble): If no CPU has been set (even if FPU/PMMU
6152 characteristics have been), default to 68020. Don't need extra
6153 quotes around error string.

6235 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6237 * write.c (write_object_file): keep the fix_tail clean, which
6238 fixes a bug in -R where relocations were being lost.
6240 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6242 * configure.in: recognize m680x0 as having sun3 emulation mode for

6287 start addresses to match required alignment.
6289 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6291 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6292 where gcc looks for it.
6294 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6296 * Makefile.in: Changed some lines to be less confusing for some

6362 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6364 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6366 * expr.c (operand): if can't work out what sort of operand it is,
6367 then look through FLT_CHARS for a hint.
6369 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6371 * Makefile.in, configure.in: removed traces of namesubdir,
6372 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6373 copyrights to '92, changed some from Cygnus to FSF.
6375 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6376 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6377 copyrights to '92, changed some from Cygnus to FSF.
6379 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6381 * expr.c: If an expression is single comma, then return with
6382 SEG_ABSENT rather than an error - since the sparc front end does
6383 really strange things with things like fbge,a
6385 * as.h: include bfd.h if using many sections
6386 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6387 local labels didn't work.
6388 * listing.c (list_symbol_table): don't core dump when there's no
6390 * write.c, write.h: call fix_new with the right number of args on
6392 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6395 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6397 * app.c: MRI compatibility - allow single quote to start a string.
6398 * as.c: fix typo recently introduced.
6399 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6400 * expr.c: Much rewriting, to accomodate MRI syntax for
6401 expressions. Also easier to read now.
6402 * listing.c: Put back defuns
6403 * read.c: modified to accept MRI syntax, put back listing pseudo
6404 ops so that an assembler built with NO_LISTING ignores list ops
6406 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6407 machine is a SPARC or a 29K.
6408 * config/obj-aout.c: added s_sect pseudo op
6409 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6410 fill in the timestamp.
6411 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6412 anymore, define all the relocs which the tc-<x> bit will use so we
6413 can translate from them to the coff types.
6414 * config/tc-a29k.c: reloc_type isn't ane enum any more
6415 * config/tc-m68k.c: Added NO_RELOC definition.
6417 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6419 * Makefile.in: put header files before C source for TAGS; remove
6420 references to non-existent syscalls.h.
6422 * read.c, write.c subsegs.c: back out the .bss changes.
6424 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6426 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6430 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6432 * symbols.c (local_label_name): symbols now start with ^A.
6434 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6435 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6436 generate these sections. .align: will use NOP_OPCODE or 0
6437 for padding. This is just for being nice to the
6440 * expr.c (operand): changed to generate local label "\001L0"
6441 starting with a ^A so that it is recognized as a local label.
6443 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6445 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6446 i/o opcodes - inb, inw, outb and outw. string manipulation with
6447 att syntax - scmp, slod, smov, ssca, ssto.
6449 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6450 to just after .file .
6452 In obj_crawl_symbol_chain() where it tries to put the external
6453 symbols apart, with the condition:
6454 (!S_IS_DEFINED(symbolP) &&
6455 !S_IS_DEBUG(symbolP) &&
6456 !SF_GET_STATICS(symbolP))
6457 it was moving too many symbols out. So I switch it back to the
6459 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6461 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6462 so that we don't use the F_RELFLG which make the linker complain
6463 that somebody has stripped the relocation info.
6465 Also, the AIX ld program require that the relocation table
6466 is sorted by r_vaddr like the standard ATT assembler does.
6468 [he also changed the sizeof(struct ...)'s into the coff
6469 style FOOSZ macros. I'm not sure this is right, but I can't
6470 remember why. xoxorich.]
6472 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6474 * Makefile.in, configure.in, doc: use the doc. Build it, install
6477 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6479 * read.c: white space and comments only.
6481 * configure.in: use the new atof-ns32.c for ns32k.
6483 * write.c: comment change only.
6485 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6486 aren't yet integrated.
6488 * tc-i860.[hc]: blew off the dust. Something must still be done
6489 about conflicting relocation types.
6491 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6494 * tc-i960.c, tc-sparc.c: white space and comments only.
6496 * tc-a29k.h: delete duplicate macro definition.
6498 * new file atof-ns32k.c copied from hack's last unreleased gas.
6500 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6502 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6505 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6506 ChangeLog's prior to this are sketchy at best. I have logs.
6507 They just aren't ChangeLogs.
6511 version-control: never
