11 elf_tc_make_sections stuff. It was there to support PA braindamage
12 which has been fixed, and in the case of elf_tc_make_sections is
13 redundant with elf_tc_final_processing.

33 don't spew remainder of input file in error message.
34 (tc_gen_reloc): If bfd_reloc_type_lookup returns null, print error
35 message with reloc type and try to process remainder of file.
37 * doc/Makefile.in (install-info-as, install-info-gasp): New
38 targets, now explicitly checking $(srcdir) for info files.

47 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
48 flag rather than signedp field. Only permit extended range if
49 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
50 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
52 * config/tc-ppc.c (ppc_size): New static variable.
53 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
54 (md_begin): If an instruction has a size specific flag set, only
55 add it if we are assembling that size.
57 Thu Mar 31 16:51:16 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
59 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
60 cross section PC relative relocs right for COFF and ELF.

70 the type of symbol set symbols which happen to be in the absolute
73 Mon Mar 28 12:35:00 1994 David Edelsohn (edelsohn@npac.syr.edu)
75 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
76 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),
77 and -many (all architectures).

88 N_INDR symbol, set BSF_EXPORT and clear BSF_LOCAL.
90 * config/tc-mips.c (append_insn): If EMBEDDED_PIC, don't swap a
91 branch with an instruction that uses $at, in case the branch is
93 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
94 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
95 to make it pcrel_offset.
96 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
97 reloc->address; another gruesome hack to get gas reloc handling to
100 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
102 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using

106 (md_assemble): Call it.
107 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
109 (lituse_pending): New variable. Set by anything that generates a
110 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
111 tested by code that might want to emit a LITUSE reloc.
112 (emit_unaligned_io): New function. Currently calls md_assemble,
113 but it should eventually be converted to generate the insn itself
114 and call emit_insn directly.
115 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
116 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
117 emit_bis_r): Likewise.

124 the value can't be resolved.
126 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
128 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
129 the -G value to 0x7fffffff. For SVR4 PIC options, don't call

142 * config/tc-mips.c (enum mips_pic_level): New enum.
143 (mips_pic): Change from int to enum mips_pic_level. Change all
144 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
145 (load_address): Handle EMBEDDED_PIC.
146 (macro): Handle EMBEDDED_PIC in all PIC cases.
147 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
148 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
149 -non_shared to use NO_PIC (this is how the Irix 5 assembler
150 works). Do not permit -G with SVR4_PIC.
151 (s_abicalls): Warn if -G was used, and force -G 0.
152 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
153 anything but a.out, not just for ELF. For ECOFF, don't generate a
154 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
156 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
158 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

164 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
166 * Makefile.in (config-stamp): If `defs' is defined, emit a
167 preprocessor directive to create a macro named by this value into
168 config.new; don't explicitly go for BFD_ASSEMBLER.
169 * configure.in: Define `defs', not `BFDDEF'. Set it to
170 MANY_SEGMENTS for any obj-coffbfd target.
171 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
172 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
174 (LOCAL_LOADLIBES): Deleted.
175 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
176 * config/m88kcoff.mt (TDEFINES): Ditto.

202 bfd_set_symtab is called.
203 (dump_section_relocs): Note whether a symbol is a section symbol
205 (adjust_reloc_syms): For now, always supply an absolute symbol for
206 fixups without symbols but not yet `done'. Use section_symbol to
207 get the symbol, instead of going directly for abs_symbol.
208 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
209 reloc is not a section symbol and is not in the symbol table.
210 (set_symtab): New function, broken out from write_object_file.
211 Counts symbol table instead of relying on an earlier count.
212 (write_object_file): Call set_symtab, but do it after potentially
213 invoking the *_frob_file macros. Don't bother counting symbols.
214 Call symbol_remove, instead of expanding it in place. Moved the
215 conditionalized `object_file_size' declaration down to
216 conditionalized block where it's used. When using the absolute
217 symbol for a fixup without a symbol, set sy_used_in_reloc.
218 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
219 the correct symbol for the absolute section.
221 * subsegs.c (section_symbol): Use symbol_new instead of
222 symbol_make, since we may want it to go into the symbol table.
223 Make the new symbol have internal linkage. If
224 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
225 symbol with the newly created GAS symbol.
226 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
227 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

232 (in_signed_range): New function.
234 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
235 (sparc_ip, label "immediate"): Reject constants for pcrel
236 instructions only if the relocation type indicates a "call"
237 instruction and the offset is within range of a "jmpl %g0". If
238 it's not in range, use the absolute section symbol plus an offset.
239 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
241 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
243 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
246 * configure.in: Eliminated all targets using obj-coff but not
247 defining BFD_ASSEMBLER; I think all such targets that are
248 supported will be matched by real CPU-OS combinations earlier in
250 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
251 some comments about the dpx2 configuration, but left it disabled,
252 since it couldn't be reached before.
253 (target a29k-amd-ebmonold): Deleted.
255 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
257 * config/tc-hppa.c (pa_import): Correctly handle importing of an
258 already defined symbol.

263 the 'j' operand if there are no further alternatives for this
266 * config/obj-coffbfd.c (adjust_stab_section): Initialize
267 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
268 is not SEG_UNKNOWN rather than checking whether it is >= 0.
270 * config/tc-mips.c (mips_align): Take new argument, label, and use
271 it instead of global insn_label.
272 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
273 call to mips_emit_delay and pass it to mips_align.
275 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
277 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
279 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
280 argument to a .callinfo directive. Don't loop forever on errors.
282 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
283 use pre-defined registers as arguments.
285 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
287 * write.c (write_object_file): Check both S_IS_LOCAL and
288 S_IS_EXTERNAL when deciding whether to discard a symbol.
290 * config-gas.com: Scan Makefile.in, not version.c, for current
291 version number. Delete all versions of temp files when finished
292 with them. Create config.h.
294 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
295 values to reduce number of lookups with S_GET_VALUE. Skip debug
296 symbols to avoid "a really nasty bug". (From Holger Teutsch,
297 holger@botbso.rhein-main.de.)
298 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
299 field. (Also from Holger Teutsch.) Watch for a would-be register
300 mask that spans frags.
302 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
303 this_base, not line_base. (Patch from Andreas Arens,
304 ari@obelix.av.rwth-aachen.de.)
306 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
307 look local if they're exported or undefined. Used to be done for
310 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
311 Get it from the looked-up symbol, instead of using the string from
312 the input stream, which is no longer null-terminated.
313 (LEX_PCT): New macro, defaults to 0.
314 (lex_type): Use it for `%'.
316 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.
317 (vip_op): Now static, and returns void. Callers changed. Added
319 (vip): Ditto. Call as_fatal directly if a program bug is

323 * Makefile.in (literal.o): Provide dependencies.
325 * configure.in: Set new makefile variable OPCODES_LIB.

378 (obj_pseudo_table): Make it available only if MANY_SECTIONS.
379 (obj_symbol_to_chars) [CROSS_COMPILE]: Some attemps to make this

2431 * configure.in: Set bfd_gas for all sparc targets. Added facility
2432 for keeping or rejecting configurations still under development;
2433 default is to assume production environment, and reject configs
2434 still being worked on. Mark Elf configurations (except sparc and
2435 i386) as developmental. Deleted cases matching some generic names
2436 in favor of more specific names. (E.g., when we get Alpha

2454 for functions only used within tc-hppa.c, likewise for structures,
2455 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2456 conditional code in a few small places.

2462 into a few places. Make all functions and variables which
2463 are only used within tc-hppa.c static. PARAMize all functions.
2464 Add comments to functions. Delete unused functions, variables,
2465 #defines, etc. Delete unused members within structures. Delete
2466 ldil;ble hacks -- it is believed they were installed to work
2467 around old gas bugs. Avoid using mixed case for local
2468 functions, variables, and structures. Fix formatting problems
2469 not found by GNU-indent. Add FIXME notices for things which
2470 should be worked on the near future. Delete lots of old

2488 * config/tc-hppa.c: Likewise.
2490 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2491 of elf32_symbol_type.
2492 (pa_export_args): Likewise.
2493 (elf_hppa_final_processing): Likewise.

2500 a multiple of the section alignment rather than always a
2503 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2544 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2546 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2547 ELF, since the ELF object format does not have these type of
2548 relocations. Change the abort into as as_bad and return
2549 BFD_RELOC_NONE to silence compiler warnings.
2550 (md_assemble): Keep track of the instruction size. Allow white
2551 space between the $ and the constant for compatibility with older
2552 gases and other assemblers.

4941 avoid some redefinition complaints on some systems.
4942 (const, volatile): Don't need these conditionally defined if we
4943 use CONST and VOLATILE from ansidecl.h.
4944 (seg_name): Use CONST, not const.

4952 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4953 (fixup_segment): Add a29k special case; the linker is not prepared
4954 to see a segment offset here.

4959 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4961 * Makefile.in: add dvi target; as-$(config).texinfo might live in
4962 srcdir, might be in objdir.

4981 * Makefile.in (targ-cpu.o): Depend on config.h.
4983 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4985 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4986 dropping a space immediately following an identifier.

4988 lines; I don't think that can be done portably.
4989 * config/tc-mips.c (macro): Use $AT if target register is zero in
4990 load instruction, which it can be for a floating point load.
4992 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

5013 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
5015 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
5016 to be on a single line.

5064 prototypes for all static functions. Moved existing minimal
5065 debugging format support info #ifndef OBJ_ECOFF blocks.

5114 * make-gas.com: Find obstack.obj if it's not in the current
5116 * read.c (s_ignore): Don't declare is_end_of_line. It's
5117 redundant, and triggers a VMS gcc compiler bug.
5119 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5120 current segment as an argument. (Ignored in all cases but VMS.)
5121 All callers and definitions changed.

5140 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
5141 Call elf_xstabs for .stabs and .xstabs operators.
5143 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
5145 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
5148 * configure.in: mips-bsd configuration was missing format spec.
5151 * Makefile.in (Makefile): Depends on configure.in.
5153 * config/tc-mips.c (append_insn): Don't check for alignment of
5154 frag in memory; alignment of instructions in section is a separate
5157 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
5160 * listing.h: Always provide function declarations, not macros, so

5418 md_relax_table): Use default zero initialization.
5419 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
5420 latter, instead of selecting with preprocessor conditionals.
5422 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
5424 * configure.in: recognise all sparclite variants

5434 * expr.c (operand): If character other than comma or newline is a
5435 logical end-of-line character, use the newline case.
5436 From Eric Youngdale:
5437 (operand): Set X_add_number field for floating-point numbers.
5438 (operand): Treat zero byte as end-of-operand.
5440 * configure.in (per-target): Look for with_bfd_assembler option.
5441 For now, only accept "no", until the merge is done.
5443 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
5444 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

5450 * expr.c: Add "const" modifier to hex_value.
5451 * symbols.c: Finish conversion to S_* macros in the VMS only
5452 parts of the program. Add "const" modifier to
5453 md_[long,short]_jump_size. Remove declaration of const_flag
5454 (which will be declared in obj-vms.h).
5455 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5456 Fix arguments to VMS_write_object_file.
5457 * config-gas.com: New file. Script for VMS systems to set up the
5458 configuration to build gas for VMS, and create config.status.
5459 * make-gas.com: Redone to work with new scheme.
5460 * obj-vms.c: Patch to fix bug where we were not correctly parsing the

5465 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5466 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5467 types of malformed stabs. Change parsing algorithm so that we are
5468 more certain of having all of the information that we need on hand.
5469 * obj-vms.c (final_forward_reference): New function, used to help
5470 resolve the data types of as many struct elements as possible

5474 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5475 as symbols as well in the object file. Look for external functions

5478 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5480 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.

5488 SEG_DATA or SEG_E1 if needed.
5489 (s_lcomm): Likewise with bss_section.
5490 (s_fill): Use memset, not bzero.
5492 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5517 mapping to segT enum values.
5518 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5519 if these are used or defined, if BFD_ASSEMBLER.
5520 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5521 subseg_new split into two functions.
5522 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5524 * as.h (volatile): Don't define if already defined.
5525 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5527 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5528 declare with format attribute for -Wformat checking.
5530 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5532 * app.c, config/tc-*.c: Don't include read.h, since it is already

5545 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5546 (DOT_LABEL_PREFIX): Define.

5548 name rather than L0\001.
5549 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5551 * symbols.c, symbols.h (local_bss_counter): Removed.
5552 * write.c (write_object_file): bss no longer uses

5560 (size_section): Restored sanity check.
5561 (do_relocs_for): Base section address on s_paddr rather than
5562 computing it. Adjust a29k R_IHIHALF special case to account for

5564 reclos, set s_relptr to 0. Set relocation size in object_headers.
5565 (fill_section): Always set s_vaddr here, removing
5566 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5567 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5568 Set STYP_INFO for .comment.
5569 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5570 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5572 H_{SET,GET}_* macros.
5573 (do_linenos_for): Set lineno size in object_headers.
5574 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5575 set s_vaddr here. If string_byte_count remains 4, set it back to
5576 0, and only write strings out if there are some. Call
5577 fill_section before do_relocs_for and do_linenos_for.
5578 (obj_coff_section): Handle optional quoted second argument giving
5579 section characteristics.
5580 (obj_coff_bss): Added to handle .bss.
5581 (obj_coff_ident): Added to handle .ident (puts string in .comment

5605 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5607 * config/obj-coff.h: Don't use #elif.
5609 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5610 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5612 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

5628 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
5630 * listing.c: Call xmalloc, not malloc; don't declare malloc.
5632 * Changes to support SCO 3.2v4:
5633 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
5634 SEG_BSS, fill with NOP_OPCODE.
5635 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
5636 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
5637 using ZERO_BASED_SEGMENTS.
5638 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5639 never set segment address for SEG_E2 (.bss) and don't write out
5640 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5641 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5642 definitions, and don't merge tags with non-tags. Check for .bf
5643 rather than just checking whether the second character is b and
5644 the third character is f.
5645 (obj_coff_val): gcc can generate values which we don't handle
5646 correctly; discard information for now, since it only affects the
5647 debugging information.

5649 (yank_symbols): Don't merge labels.
5650 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5652 set segment address if ZERO_BASED_SEGMENTS.
5653 (obj_coff_section): Accept and ignore a trailing quoted string, as
5654 used in AT&T i386 syntax.

5656 relative addends by the segment vaddr.
5657 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
5658 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
5659 * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

5760 xrealloc from xrealloc.c.
5761 * xrealloc.c: Deleted.
5762 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
5764 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
5767 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
5769 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;

5788 * all files: Whitespace changes for GNU indentation style, done by
5789 GNU `indent'. Some cleanup still needed, especially of comments.
5791 * configure.in: No te-386bsd.h file exists; don't try to use it.
5793 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
5795 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
5796 could be doing emulation.
5798 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5801 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
5804 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
5806 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

5830 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5832 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5833 constant will not fit in an immediate field.
5834 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5856 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
5858 * version.c: Put conditional "const" before version_string, not

5869 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5871 * Support for i386-sysv.
5872 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5876 (fill_section): Don't set STYP_NOLOAD for .bss section.
5877 (fixup_segment): 386 uses strange common symbol format.

5910 * tc-z8k.c: lots of bug fixes
5912 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5914 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5915 #elif, since it is not supported by old compilers.
5916 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5917 couple of expressions in tc-m68k.c.
5919 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5921 * read.c (cons): If NO_RELOC is defined, use it.
5923 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5925 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5927 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5928 local labels to start with a .) and set REGISTER_PREFIX to %.
5929 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5931 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
5933 * messages.c: Comment changes.
5935 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

5938 * messages.c: If __STDC__ is not defined, define NO_STDARG.
5940 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
5942 * listing.c (debugging_pseudo): Add stabs and stabn as things to
5945 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5947 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5948 sections starting from zero, rather than making them consecutive.
5949 This makes subsequent reloc calculations easier, esp if the object
5950 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5951 allocate lcomm in .data rather than in .bss. It seems that some
5952 tools can't cope with a non-zero sized bss before linkage.
5954 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5956 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
5957 throughout. That enum no longer means what we thought it meant.

5960 "-mno-688[58]1" options.
5962 * tc-m68k.c: Added CPU32 support.

5970 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
5971 Change LIBDEPS dependence to LIBS.
5973 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
5975 * Makefile.in (install): if $(tooldir) exists, install as in
5978 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5980 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5981 .word is < -32768 or > 32767. The -J flag causes the error to be
5982 ignored. This is to catch over-sized switches generated by gcc on
5983 systems which don't support the broken .word hack.
5984 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5985 write.c (fixup_segment): check for signed .word overflow if
5986 WARN_SIGNED_OVERFLOW_WORD.
5988 * write.c (fixup_segment): fixed missing parens in expression
5989 checking for byte or word overflow.
5991 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
5992 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
5993 WARN_SIGNED_OVERFLOW_WORD.

6003 * tc-i386.h : new coff defines
6005 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
6007 * input-scrub.c (input_scrub_push): call input_file_begin, not
6009 messages.c (as_perror): print ": " between the passed in error and
6010 the strerror, like perror does.
6012 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
6014 * Makefile.in: use gas_target instead of modifying target_cpu.
6015 From Steve Chamberlain:
6016 Makefile.in: Handle m68*-*-coff*.
6017 read.c, read.h: add mult argument to s_space
6019 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6020 Motorola and MIT syntax; gas can now assemble either type of
6022 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6024 m68kcoff.mt: for m68k COFF.
6025 obj-coffbfd.c: (fixup_mdeps) added
6026 (size_section) removed bad sanity check
6027 (fill_section) added rs_machine_dependent case
6028 (write_object_file) call fixup_mdeps
6029 (fixup_segment) set fx_subsy to 0.
6030 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6032 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6035 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6037 * Makefile.in (LIBS): Include opcode library.
6039 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
6041 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers

6059 tc-i960.c (md_ri_to_chars): Always output bout object file in
6060 little endian byte order (used to use endianness of host).
6062 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6064 * config/tc-m68k.c (init_table): Now const. Always include 68851
6065 data, so that "bc" is available to 68040 cache instructions.
6066 Added "tt0", "tt1", and 68ec030 variants.
6067 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6068 (enum _register): Added TT0, TT1.
6069 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6070 line number correctly in "internal error" messages. Don't print
6071 architecture-mismatch message for operand errors.
6073 From Colin Smith (colin@wrs.com):
6074 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6075 than install_operand.
6077 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6079 * listing.c (buffer_line): rewind to the start of include
6080 files, they might be included twice.
6082 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
6084 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
6086 * Makefile.in: defined TARGET_CPU for C code so that it can choose
6087 one element of a family.
6089 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
6091 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6092 so that we can assemble hand-written libgcc code.
6094 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6096 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6097 has already been formatted (but may still contain %-characters).
6100 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6102 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6103 written with indirection on the last two operands, which can be
6104 either data or address registers. Added a new operand type 'r'

6355 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6357 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6358 where gcc looks for it.
6360 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6362 * Makefile.in: Changed some lines to be less confusing for some

6432 * expr.c (operand): if can't work out what sort of operand it is,
6433 then look through FLT_CHARS for a hint.
6435 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6437 * Makefile.in, configure.in: removed traces of namesubdir,

6441 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6442 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6443 copyrights to '92, changed some from Cygnus to FSF.
6445 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6447 * expr.c: If an expression is single comma, then return with
6448 SEG_ABSENT rather than an error - since the sparc front end does
6449 really strange things with things like fbge,a
6451 * as.h: include bfd.h if using many sections
6452 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6453 local labels didn't work.
6454 * listing.c (list_symbol_table): don't core dump when there's no
6456 * write.c, write.h: call fix_new with the right number of args on
6458 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6461 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6463 * app.c: MRI compatibility - allow single quote to start a string.
6464 * as.c: fix typo recently introduced.
6465 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6466 * expr.c: Much rewriting, to accomodate MRI syntax for
6467 expressions. Also easier to read now.
6468 * listing.c: Put back defuns
6469 * read.c: modified to accept MRI syntax, put back listing pseudo
6470 ops so that an assembler built with NO_LISTING ignores list ops
6472 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6473 machine is a SPARC or a 29K.
6474 * config/obj-aout.c: added s_sect pseudo op
6475 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6476 fill in the timestamp.
6477 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6478 anymore, define all the relocs which the tc-<x> bit will use so we
6479 can translate from them to the coff types.
6480 * config/tc-a29k.c: reloc_type isn't ane enum any more
6481 * config/tc-m68k.c: Added NO_RELOC definition.
6483 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6485 * Makefile.in: put header files before C source for TAGS; remove
6486 references to non-existent syscalls.h.
6488 * read.c, write.c subsegs.c: back out the .bss changes.
6490 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6492 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6496 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6498 * symbols.c (local_label_name): symbols now start with ^A.
6500 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6501 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6502 generate these sections. .align: will use NOP_OPCODE or 0
6503 for padding. This is just for being nice to the
6506 * expr.c (operand): changed to generate local label "\001L0"
6507 starting with a ^A so that it is recognized as a local label.
6509 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6511 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6512 i/o opcodes - inb, inw, outb and outw. string manipulation with
6513 att syntax - scmp, slod, smov, ssca, ssto.
6515 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6516 to just after .file .
6518 In obj_crawl_symbol_chain() where it tries to put the external
6519 symbols apart, with the condition:
6520 (!S_IS_DEFINED(symbolP) &&
6521 !S_IS_DEBUG(symbolP) &&
6522 !SF_GET_STATICS(symbolP))
6523 it was moving too many symbols out. So I switch it back to the
6525 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6527 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6528 so that we don't use the F_RELFLG which make the linker complain
6529 that somebody has stripped the relocation info.
6531 Also, the AIX ld program require that the relocation table
6532 is sorted by r_vaddr like the standard ATT assembler does.
6534 [he also changed the sizeof(struct ...)'s into the coff
6535 style FOOSZ macros. I'm not sure this is right, but I can't
6536 remember why. xoxorich.]
6538 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

6547 * configure.in: use the new atof-ns32.c for ns32k.
6549 * write.c: comment change only.
6551 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6552 aren't yet integrated.
6554 * tc-i860.[hc]: blew off the dust. Something must still be done
6555 about conflicting relocation types.
6557 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6560 * tc-i960.c, tc-sparc.c: white space and comments only.
6562 * tc-a29k.h: delete duplicate macro definition.
6564 * new file atof-ns32k.c copied from hack's last unreleased gas.
6566 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6568 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6571 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6572 ChangeLog's prior to this are sketchy at best. I have logs.
6573 They just aren't ChangeLogs.
6577 version-control: never
