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

28 * config/tc-ppc.c (ppc_insert_operand): Check PPC_OPERAND_SIGNED
29 flag rather than signedp field. Only permit extended range if
30 PPC_OPERAND_SIGNOPT flag is set and assembling in 32 bit mode.
31 Based on patch from David Edelsohn (edelsohn@npac.syr.edu).
33 * config/tc-ppc.c (ppc_size): New static variable.
34 (ppc_arch): Check for PPC_OPCODE_PPC before PPC_OPCODE_POWER.
35 (md_begin): If an instruction has a size specific flag set, only

56 * config/tc-ppc.c (md_parse_option): Add -mpwrx (POWER/2 aka
57 RIOS2), -mpwr (POWER aka RIOS1), -mppc (PowerPC aka MPC603/604),

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

87 (md_assemble): Call it.
88 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
90 (lituse_pending): New variable. Set by anything that generates a
91 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
92 tested by code that might want to emit a LITUSE reloc.
93 (emit_unaligned_io): New function. Currently calls md_assemble,
94 but it should eventually be converted to generate the insn itself
95 and call emit_insn directly.
96 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
97 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
98 emit_bis_r): Likewise.

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

125 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
126 (load_address): Handle EMBEDDED_PIC.
127 (macro): Handle EMBEDDED_PIC in all PIC cases.
128 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
129 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
130 -non_shared to use NO_PIC (this is how the Irix 5 assembler
131 works). Do not permit -G with SVR4_PIC.
132 (s_abicalls): Warn if -G was used, and force -G 0.
133 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
134 anything but a.out, not just for ELF. For ECOFF, don't generate a
135 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
137 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
139 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

145 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
147 * Makefile.in (config-stamp): If `defs' is defined, emit a
148 preprocessor directive to create a macro named by this value into
149 config.new; don't explicitly go for BFD_ASSEMBLER.
150 * configure.in: Define `defs', not `BFDDEF'. Set it to
151 MANY_SEGMENTS for any obj-coffbfd target.
152 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
153 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
155 (LOCAL_LOADLIBES): Deleted.
156 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
157 * config/m88kcoff.mt (TDEFINES): Ditto.

183 bfd_set_symtab is called.
184 (dump_section_relocs): Note whether a symbol is a section symbol
186 (adjust_reloc_syms): For now, always supply an absolute symbol for
187 fixups without symbols but not yet `done'. Use section_symbol to
188 get the symbol, instead of going directly for abs_symbol.
189 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
190 reloc is not a section symbol and is not in the symbol table.
191 (set_symtab): New function, broken out from write_object_file.
192 Counts symbol table instead of relying on an earlier count.
193 (write_object_file): Call set_symtab, but do it after potentially
194 invoking the *_frob_file macros. Don't bother counting symbols.
195 Call symbol_remove, instead of expanding it in place. Moved the
196 conditionalized `object_file_size' declaration down to
197 conditionalized block where it's used. When using the absolute
198 symbol for a fixup without a symbol, set sy_used_in_reloc.
199 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
200 the correct symbol for the absolute section.
202 * subsegs.c (section_symbol): Use symbol_new instead of
203 symbol_make, since we may want it to go into the symbol table.
204 Make the new symbol have internal linkage. If
205 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
206 symbol with the newly created GAS symbol.
207 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
208 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

213 (in_signed_range): New function.
215 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
216 (sparc_ip, label "immediate"): Reject constants for pcrel
217 instructions only if the relocation type indicates a "call"
218 instruction and the offset is within range of a "jmpl %g0". If
219 it's not in range, use the absolute section symbol plus an offset.
220 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
222 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
224 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
227 * configure.in: Eliminated all targets using obj-coff but not
228 defining BFD_ASSEMBLER; I think all such targets that are
229 supported will be matched by real CPU-OS combinations earlier in
231 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
232 some comments about the dpx2 configuration, but left it disabled,
233 since it couldn't be reached before.
234 (target a29k-amd-ebmonold): Deleted.
236 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

244 the 'j' operand if there are no further alternatives for this
247 * config/obj-coffbfd.c (adjust_stab_section): Initialize
248 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
249 is not SEG_UNKNOWN rather than checking whether it is >= 0.
251 * config/tc-mips.c (mips_align): Take new argument, label, and use
252 it instead of global insn_label.
253 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
254 call to mips_emit_delay and pass it to mips_align.
256 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
258 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
260 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
261 argument to a .callinfo directive. Don't loop forever on errors.
263 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
264 use pre-defined registers as arguments.
266 Mon Mar 14 14:29:45 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
268 * write.c (write_object_file): Check both S_IS_LOCAL and
269 S_IS_EXTERNAL when deciding whether to discard a symbol.
271 * config-gas.com: Scan Makefile.in, not version.c, for current
272 version number. Delete all versions of temp files when finished
273 with them. Create config.h.
275 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
276 values to reduce number of lookups with S_GET_VALUE. Skip debug
277 symbols to avoid "a really nasty bug". (From Holger Teutsch,
278 holger@botbso.rhein-main.de.)
279 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
280 field. (Also from Holger Teutsch.) Watch for a would-be register
281 mask that spans frags.
283 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
284 this_base, not line_base. (Patch from Andreas Arens,
285 ari@obelix.av.rwth-aachen.de.)
287 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
288 look local if they're exported or undefined. Used to be done for
291 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

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

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

2412 * configure.in: Set bfd_gas for all sparc targets. Added facility
2413 for keeping or rejecting configurations still under development;
2414 default is to assume production environment, and reject configs
2415 still being worked on. Mark Elf configurations (except sparc and
2416 i386) as developmental. Deleted cases matching some generic names
2417 in favor of more specific names. (E.g., when we get Alpha

2434 through inclusion of tc-hppa.h. Delete all forward declarations
2435 for functions only used within tc-hppa.c, likewise for structures,
2436 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2437 conditional code in a few small places.
2439 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2440 structures, global variables, forward declarations together.

2442 conditional code -- try to group conditional code together
2443 into a few places. Make all functions and variables which
2444 are only used within tc-hppa.c static. PARAMize all functions.
2445 Add comments to functions. Delete unused functions, variables,
2446 #defines, etc. Delete unused members within structures. Delete
2447 ldil;ble hacks -- it is believed they were installed to work
2448 around old gas bugs. Avoid using mixed case for local
2449 functions, variables, and structures. Fix formatting problems
2450 not found by GNU-indent. Add FIXME notices for things which
2451 should be worked on the near future. Delete lots of old
2452 useless (1.36 PA-SOM) code.

2464 which do not involve function symbols.
2466 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
2467 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
2469 * config/tc-hppa.c: Likewise.
2471 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
2472 of elf32_symbol_type.
2473 (pa_export_args): Likewise.
2474 (elf_hppa_final_processing): Likewise.
2475 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

2481 a multiple of the section alignment rather than always a
2484 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
2485 bits are zero (eg they specify no relocations), then do not even
2486 bother adding their entries to thesymextn section.

2523 instead add a second loop over special_chars. Set alignment
2524 of text, data and bss sections to 4.
2525 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2527 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2528 ELF, since the ELF object format does not have these type of
2529 relocations. Change the abort into as as_bad and return
2530 BFD_RELOC_NONE to silence compiler warnings.
2531 (md_assemble): Keep track of the instruction size. Allow white
2532 space between the $ and the constant for compatibility with older
2533 gases and other assemblers.

4873 a29k .bss section; the mondfe program doesn't like it.

4894 source directory, if that's not the current directory.
4896 * configure.in (per-host): Accept MIPS host with BSD version

4922 avoid some redefinition complaints on some systems.
4923 (const, volatile): Don't need these conditionally defined if we
4924 use CONST and VOLATILE from ansidecl.h.
4925 (seg_name): Use CONST, not const.
4927 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
4929 * config/tc-mips.c: Reindented to GNU standards.

4933 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
4934 (fixup_segment): Add a29k special case; the linker is not prepared
4935 to see a segment offset here.
4937 * app.c (do_scrub_next_char): Added new state, 10, modifying state

4940 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4942 * Makefile.in: add dvi target; as-$(config).texinfo might live in
4943 srcdir, might be in objdir.

4962 * Makefile.in (targ-cpu.o): Depend on config.h.
4964 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
4966 * app.c (do_scrub_next_char): Added new state, 9, to avoid
4967 dropping a space immediately following an identifier.
4968 * expr.c, write.c: Rewrote assert expressions to not use multiple
4969 lines; I don't think that can be done portably.
4970 * config/tc-mips.c (macro): Use $AT if target register is zero in
4971 load instruction, which it can be for a floating point load.
4973 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4994 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
4996 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
4997 to be on a single line.

5045 prototypes for all static functions. Moved existing minimal
5046 debugging format support info #ifndef OBJ_ECOFF blocks.

5095 * make-gas.com: Find obstack.obj if it's not in the current
5097 * read.c (s_ignore): Don't declare is_end_of_line. It's
5098 redundant, and triggers a VMS gcc compiler bug.
5100 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
5101 current segment as an argument. (Ignored in all cases but VMS.)
5102 All callers and definitions changed.

5121 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
5122 Call elf_xstabs for .stabs and .xstabs operators.

5132 * Makefile.in (Makefile): Depends on configure.in.
5134 * config/tc-mips.c (append_insn): Don't check for alignment of
5135 frag in memory; alignment of instructions in section is a separate

5399 md_relax_table): Use default zero initialization.
5400 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

5415 * expr.c (operand): If character other than comma or newline is a
5416 logical end-of-line character, use the newline case.

5418 (operand): Set X_add_number field for floating-point numbers.
5419 (operand): Treat zero byte as end-of-operand.
5421 * configure.in (per-target): Look for with_bfd_assembler option.
5422 For now, only accept "no", until the merge is done.
5424 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):

5434 md_[long,short]_jump_size. Remove declaration of const_flag
5435 (which will be declared in obj-vms.h).
5436 * write.c: Add "const" modifier to md_[long,short]_jump_size.
5437 Fix arguments to VMS_write_object_file.
5438 * config-gas.com: New file. Script for VMS systems to set up the

5447 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5448 types of malformed stabs. Change parsing algorithm so that we are
5449 more certain of having all of the information that we need on hand.
5450 * obj-vms.c (final_forward_reference): New function, used to help
5451 resolve the data types of as many struct elements as possible

5455 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5456 as symbols as well in the object file. Look for external functions

5469 SEG_DATA or SEG_E1 if needed.
5470 (s_lcomm): Likewise with bss_section.
5471 (s_fill): Use memset, not bzero.

5500 if these are used or defined, if BFD_ASSEMBLER.
5501 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5502 subseg_new split into two functions.
5503 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5505 * as.h (volatile): Don't define if already defined.
5506 (had_errors, had_warnings): Provide prototypes for ANSI C even if

5541 (size_section): Restored sanity check.
5542 (do_relocs_for): Base section address on s_paddr rather than
5543 computing it. Adjust a29k R_IHIHALF special case to account for

5545 reclos, set s_relptr to 0. Set relocation size in object_headers.
5546 (fill_section): Always set s_vaddr here, removing
5547 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5548 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5549 Set STYP_INFO for .comment.

5553 H_{SET,GET}_* macros.
5554 (do_linenos_for): Set lineno size in object_headers.
5555 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5556 set s_vaddr here. If string_byte_count remains 4, set it back to
5557 0, and only write strings out if there are some. Call
5558 fill_section before do_relocs_for and do_linenos_for.
5559 (obj_coff_section): Handle optional quoted second argument giving
5560 section characteristics.
5561 (obj_coff_bss): Added to handle .bss.

5588 * config/obj-coff.h: Don't use #elif.
5590 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5591 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
5593 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
5595 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

5621 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5622 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5623 definitions, and don't merge tags with non-tags. Check for .bf
5624 rather than just checking whether the second character is b and
5625 the third character is f.
5626 (obj_coff_val): gcc can generate values which we don't handle
5627 correctly; discard information for now, since it only affects the
5628 debugging information.

5630 (yank_symbols): Don't merge labels.
5631 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5633 set segment address if ZERO_BASED_SEGMENTS.
5634 (obj_coff_section): Accept and ignore a trailing quoted string, as
5635 used in AT&T i386 syntax.

5743 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
5745 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
5748 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.

5777 could be doing emulation.
5779 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5782 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

5811 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5813 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5814 constant will not fit in an immediate field.
5815 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5850 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5852 * Support for i386-sysv.
5853 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

5857 (fill_section): Don't set STYP_NOLOAD for .bss section.
5858 (fixup_segment): 386 uses strange common symbol format.

5891 * tc-z8k.c: lots of bug fixes
5893 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5895 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5896 #elif, since it is not supported by old compilers.
5897 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5898 couple of expressions in tc-m68k.c.
5900 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5902 * read.c (cons): If NO_RELOC is defined, use it.
5904 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5906 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5908 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5909 local labels to start with a .) and set REGISTER_PREFIX to %.
5910 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
5912 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

5923 * listing.c (debugging_pseudo): Add stabs and stabn as things to
5926 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5928 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5929 sections starting from zero, rather than making them consecutive.
5930 This makes subsequent reloc calculations easier, esp if the object
5931 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5932 allocate lcomm in .data rather than in .bss. It seems that some
5933 tools can't cope with a non-zero sized bss before linkage.
5935 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5937 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
5938 throughout. That enum no longer means what we thought it meant.

5941 "-mno-688[58]1" options.
5943 * tc-m68k.c: Added CPU32 support.

5952 Change LIBDEPS dependence to LIBS.
5954 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
5956 * Makefile.in (install): if $(tooldir) exists, install as in
5959 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5961 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5962 .word is < -32768 or > 32767. The -J flag causes the error to be
5963 ignored. This is to catch over-sized switches generated by gcc on
5964 systems which don't support the broken .word hack.
5965 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5966 write.c (fixup_segment): check for signed .word overflow if
5967 WARN_SIGNED_OVERFLOW_WORD.
5969 * write.c (fixup_segment): fixed missing parens in expression
5970 checking for byte or word overflow.
5972 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

5986 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5988 * input-scrub.c (input_scrub_push): call input_file_begin, not
5990 messages.c (as_perror): print ": " between the passed in error and
5991 the strerror, like perror does.

5996 From Steve Chamberlain:
5997 Makefile.in: Handle m68*-*-coff*.
5998 read.c, read.h: add mult argument to s_space
6000 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
6001 Motorola and MIT syntax; gas can now assemble either type of
6003 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

6009 (write_object_file) call fixup_mdeps
6010 (fixup_segment) set fx_subsy to 0.
6011 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
6013 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
6016 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6018 * Makefile.in (LIBS): Include opcode library.
6020 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

6040 tc-i960.c (md_ri_to_chars): Always output bout object file in
6041 little endian byte order (used to use endianness of host).
6043 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6045 * config/tc-m68k.c (init_table): Now const. Always include 68851
6046 data, so that "bc" is available to 68040 cache instructions.
6047 Added "tt0", "tt1", and 68ec030 variants.
6048 (md_assemble): Complain if 68000 (only) and 68881 are specified.
6049 (enum _register): Added TT0, TT1.
6050 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
6051 line number correctly in "internal error" messages. Don't print
6052 architecture-mismatch message for operand errors.
6054 From Colin Smith (colin@wrs.com):
6055 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
6056 than install_operand.
6058 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
6060 * listing.c (buffer_line): rewind to the start of include
6061 files, they might be included twice.
6063 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
6065 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
6067 * Makefile.in: defined TARGET_CPU for C code so that it can choose
6068 one element of a family.
6070 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
6072 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
6073 so that we can assemble hand-written libgcc code.
6075 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
6077 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
6078 has already been formatted (but may still contain %-characters).
6081 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
6083 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
6084 written with indirection on the last two operands, which can be
6085 either data or address registers. Added a new operand type 'r'
6086 which accepts either register type. Added '(' to notend stuff in
6087 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
6089 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
6091 * as.h (enum _relax_state): Start off at one, not zero, to better
6092 catch uninitialized-variable errors.

6100 data_last_frag): No longer static.
6101 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
6102 defined, call it. Change segments before calling fixup_segment.
6103 (relax_align): If linkrelax, provide extra padding.
6105 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
6106 their not having symbols associated.
6108 * tc-i960.c (norelax, instrument_branches): Default initializer is
6110 (linkrelax): Delete variable definition.
6111 (mem_fmt): Call fix_new with NO_RELOC.

6282 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
6284 * write.c (write_object_file): keep the fix_tail clean, which
6285 fixes a bug in -R where relocations were being lost.
6287 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
6289 * configure.in: recognize m680x0 as having sun3 emulation mode for

6336 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
6338 * Makefile.in (install): Install into $(tooldir)/bin, since that's
6339 where gcc looks for it.
6341 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
6343 * Makefile.in: Changed some lines to be less confusing for some

6409 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
6411 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
6413 * expr.c (operand): if can't work out what sort of operand it is,
6414 then look through FLT_CHARS for a hint.
6416 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6418 * Makefile.in, configure.in: removed traces of namesubdir,
6419 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6420 copyrights to '92, changed some from Cygnus to FSF.
6422 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6423 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6424 copyrights to '92, changed some from Cygnus to FSF.
6426 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6428 * expr.c: If an expression is single comma, then return with
6429 SEG_ABSENT rather than an error - since the sparc front end does
6430 really strange things with things like fbge,a
6432 * as.h: include bfd.h if using many sections
6433 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6434 local labels didn't work.
6435 * listing.c (list_symbol_table): don't core dump when there's no
6437 * write.c, write.h: call fix_new with the right number of args on
6439 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6442 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6444 * app.c: MRI compatibility - allow single quote to start a string.
6445 * as.c: fix typo recently introduced.
6446 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6447 * expr.c: Much rewriting, to accomodate MRI syntax for
6448 expressions. Also easier to read now.
6449 * listing.c: Put back defuns
6450 * read.c: modified to accept MRI syntax, put back listing pseudo
6451 ops so that an assembler built with NO_LISTING ignores list ops
6453 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6454 machine is a SPARC or a 29K.
6455 * config/obj-aout.c: added s_sect pseudo op
6456 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6457 fill in the timestamp.
6458 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6459 anymore, define all the relocs which the tc-<x> bit will use so we
6460 can translate from them to the coff types.
6461 * config/tc-a29k.c: reloc_type isn't ane enum any more
6462 * config/tc-m68k.c: Added NO_RELOC definition.
6464 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6466 * Makefile.in: put header files before C source for TAGS; remove
6467 references to non-existent syscalls.h.
6469 * read.c, write.c subsegs.c: back out the .bss changes.
6471 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6473 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6477 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6479 * symbols.c (local_label_name): symbols now start with ^A.
6481 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6482 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6483 generate these sections. .align: will use NOP_OPCODE or 0
6484 for padding. This is just for being nice to the
6487 * expr.c (operand): changed to generate local label "\001L0"
6488 starting with a ^A so that it is recognized as a local label.
6490 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6492 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6493 i/o opcodes - inb, inw, outb and outw. string manipulation with
6494 att syntax - scmp, slod, smov, ssca, ssto.
6496 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6497 to just after .file .
6499 In obj_crawl_symbol_chain() where it tries to put the external
6500 symbols apart, with the condition:
6501 (!S_IS_DEFINED(symbolP) &&
6502 !S_IS_DEBUG(symbolP) &&
6503 !SF_GET_STATICS(symbolP))
6504 it was moving too many symbols out. So I switch it back to the
6506 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6508 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6509 so that we don't use the F_RELFLG which make the linker complain
6510 that somebody has stripped the relocation info.
6512 Also, the AIX ld program require that the relocation table
6513 is sorted by r_vaddr like the standard ATT assembler does.
6515 [he also changed the sizeof(struct ...)'s into the coff
6516 style FOOSZ macros. I'm not sure this is right, but I can't
6517 remember why. xoxorich.]
6519 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6521 * Makefile.in, configure.in, doc: use the doc. Build it, install

6526 * read.c: white space and comments only.
6528 * configure.in: use the new atof-ns32.c for ns32k.
6530 * write.c: comment change only.
6532 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6533 aren't yet integrated.
6535 * tc-i860.[hc]: blew off the dust. Something must still be done
6536 about conflicting relocation types.
6538 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6541 * tc-i960.c, tc-sparc.c: white space and comments only.
6543 * tc-a29k.h: delete duplicate macro definition.
6545 * new file atof-ns32k.c copied from hack's last unreleased gas.
6547 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6549 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6552 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6553 ChangeLog's prior to this are sketchy at best. I have logs.
6554 They just aren't ChangeLogs.
6558 version-control: never
