4 (pa_callinfo): Insert framesize into the unwind information as
5 soon as it's available.

11 an example of marker relocations.
12 * write.c (write_relocs): Instead of assuming size of a relocation
13 is 4 bytes, pick up the size from relocation itself.
14 (fixup_segment): Do not complain that a value is too small for

41 BFD_RELOC_MIPS_GPREL. Added new case a.
42 (set_at, load_register, macro): Changed calls to macro_build to
43 pass new argument for i, j and o cases.

118 (pa_parse_space_stmt): Create a new segment/space if create_flag
119 is true, and the space name is not one of the two predefined spaces.
120 (pa_subspace): Use current_space rather than a lookup via
121 pa_segment_to_space. Reset BFD section flags as required by
122 the .subspace directive. Likewise for the section alignment.
123 Pass the current space to update_subspace and create_new_subspace.
124 (pa_spaces_begin): Only use space/subspace aliases if USE_ALIASES
125 is true. When not using aliases, create a BFD section for each
126 subspace encountered. When not using aliases replace the default
127 text, data, and bss segments with new ones.

386 * config/tc-sparc.c (md_end): Function deleted.

397 against placing additional object-file dependent code here. Warn
398 against contaminating all of GAS with the internals of tc-hppa.c
399 through inclusion of tc-hppa.h. Delete all forward declarations
400 for functions only used within tc-hppa.c, likewise for structures,
401 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
402 conditional code in a few small places.
404 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
405 structures, global variables, forward declarations together.
406 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
407 conditional code -- try to group conditional code together
408 into a few places. Make all functions and variables which
409 are only used within tc-hppa.c static. PARAMize all functions.
410 Add comments to functions. Delete unused functions, variables,
411 #defines, etc. Delete unused members within structures. Delete
412 ldil;ble hacks -- it is believed they were installed to work
413 around old gas bugs. Avoid using mixed case for local
414 functions, variables, and structures. Fix formatting problems
415 not found by GNU-indent. Add FIXME notices for things which
416 should be worked on the near future. Delete lots of old
417 useless (1.36 PA-SOM) code.

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

490 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
492 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
493 ELF, since the ELF object format does not have these type of
494 relocations. Change the abort into as as_bad and return
495 BFD_RELOC_NONE to silence compiler warnings.
496 (md_assemble): Keep track of the instruction size. Allow white
497 space between the $ and the constant for compatibility with older

1560 * Extensive changes to permit symbols to contain any expression
1561 type and to delay the computation of the expression until the
1562 value is actually needed. This permits setting symbols to values
1563 calculated based on object code size. Expressions were changed to
1564 no longer be in a section, to stop the overloading of segment and
1565 expression type that previously occurred.
1567 * as.c (big_section, pass1_section, diff_section, absent_section):
1569 (expr_section): Added (used for dummy symbols which hold

2835 dependencies are read, not when they are used).
2837 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
2838 a29k .bss section; the mondfe program doesn't like it.

2883 process relocs if there aren't any relocs to process. Avoids
2884 malloc/free bug on SCO too.
2886 * as.h: Move local include files below system include files, to
2887 avoid some redefinition complaints on some systems.
2888 (const, volatile): Don't need these conditionally defined if we
2889 use CONST and VOLATILE from ansidecl.h.
2890 (seg_name): Use CONST, not const.
2892 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
2894 * config/tc-mips.c: Reindented to GNU standards.

2898 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
2899 (fixup_segment): Add a29k special case; the linker is not prepared
2900 to see a segment offset here.

2905 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
2907 * Makefile.in: add dvi target; as-$(config).texinfo might live in

2923 bignums, but don't emit error message.
2925 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
2927 * Makefile.in (targ-cpu.o): Depend on config.h.
2929 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
2931 * app.c (do_scrub_next_char): Added new state, 9, to avoid
2932 dropping a space immediately following an identifier.
2933 * expr.c, write.c: Rewrote assert expressions to not use multiple
2934 lines; I don't think that can be done portably.
2935 * config/tc-mips.c (macro): Use $AT if target register is zero in
2936 load instruction, which it can be for a floating point load.
2938 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

2959 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
2961 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
2962 to be on a single line.
2964 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
2966 * Makefile.in (config.h): Create file, writing out definitions of

3009 * config/tc-mips.c: Rearranged for ECOFF support. Added
3010 prototypes for all static functions. Moved existing minimal
3011 debugging format support info #ifndef OBJ_ECOFF blocks.

3060 * make-gas.com: Find obstack.obj if it's not in the current
3062 * read.c (s_ignore): Don't declare is_end_of_line. It's
3063 redundant, and triggers a VMS gcc compiler bug.
3065 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3066 current segment as an argument. (Ignored in all cases but VMS.)
3067 All callers and definitions changed.

3363 * config/tc-sparc.c (architecture_requested, warn_on_bump,
3364 md_relax_table): Use default zero initialization.
3365 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3366 latter, instead of selecting with preprocessor conditionals.
3368 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3370 * configure.in: recognise all sparclite variants
3372 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

3378 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3380 * expr.c (operand): If character other than comma or newline is a
3381 logical end-of-line character, use the newline case.
3382 From Eric Youngdale:
3383 (operand): Set X_add_number field for floating-point numbers.
3384 (operand): Treat zero byte as end-of-operand.
3386 * configure.in (per-target): Look for with_bfd_assembler option.
3387 For now, only accept "no", until the merge is done.
3389 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3390 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
3391 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
3392 * read.c: Finish conversion to S_* macros in the VMS only
3393 parts of the program. Add "const" modifier to hex_value.

3396 * expr.c: Add "const" modifier to hex_value.
3397 * symbols.c: Finish conversion to S_* macros in the VMS only
3398 parts of the program. Add "const" modifier to
3399 md_[long,short]_jump_size. Remove declaration of const_flag
3400 (which will be declared in obj-vms.h).
3401 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3402 Fix arguments to VMS_write_object_file.
3403 * config-gas.com: New file. Script for VMS systems to set up the
3404 configuration to build gas for VMS, and create config.status.
3405 * make-gas.com: Redone to work with new scheme.
3406 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3408 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
3409 will swap bytes if needed on a big endian system. Use throughout
3411 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3412 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3413 types of malformed stabs. Change parsing algorithm so that we are
3414 more certain of having all of the information that we need on hand.
3415 * obj-vms.c (final_forward_reference): New function, used to help
3416 resolve the data types of as many struct elements as possible
3417 when some part of the struct is not fully defined by the compiler.

3420 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3421 as symbols as well in the object file. Look for external functions
3422 that start with "__vt.", and turn them into variables, since the
3423 g++ compiler is incapable of doing this.
3424 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3426 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
3427 * input-scrub.c (as_where): Fix bug where as would crash if we did not
3428 have the name of the source file yet.
3429 * config/ho-vms.h: define HO_VMS, not HO_VAX.
3431 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
3433 * read.c (s_data): Always use "data_section", since it'll map to
3434 SEG_DATA or SEG_E1 if needed.
3435 (s_lcomm): Likewise with bss_section.
3436 (s_fill): Use memset, not bzero.
3438 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

3459 (section_alignment): Declare only if not BFD_ASSEMBLER.
3460 (big_section, reg_section, pass1_section, diff_section,
3461 absent_section, text_section, data_section, bss_section): If
3462 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3463 mapping to segT enum values.
3464 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3465 if these are used or defined, if BFD_ASSEMBLER.
3466 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3467 subseg_new split into two functions.
3468 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3470 * as.h (volatile): Don't define if already defined.
3471 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3473 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3474 declare with format attribute for -Wformat checking.
3476 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3478 * app.c, config/tc-*.c: Don't include read.h, since it is already
3481 * These are based on patches from Minh Tran-le
3482 <mtranle@paris.intellicorp.com>.
3483 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3484 obj_format coffbfd and gas_target i386coff for target.
3485 (i[34]86-*-isc*): New host (uses sysv).
3486 * config/i386aix.mt: Removed (no longer used).
3487 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3489 (LDFLAGS): Added, defined as -shlib.
3490 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3491 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3492 (DOT_LABEL_PREFIX): Define.
3493 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3494 name rather than L0\001.
3495 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3497 * symbols.c, symbols.h (local_bss_counter): Removed.
3498 * write.c (write_object_file): bss no longer uses

3506 (size_section): Restored sanity check.
3507 (do_relocs_for): Base section address on s_paddr rather than
3508 computing it. Adjust a29k R_IHIHALF special case to account for
3509 section paddr (used to require paddr to be zero). If there are no
3510 reclos, set s_relptr to 0. Set relocation size in object_headers.
3511 (fill_section): Always set s_vaddr here, removing
3512 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3513 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3514 Set STYP_INFO for .comment.

3518 H_{SET,GET}_* macros.
3519 (do_linenos_for): Set lineno size in object_headers.
3520 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3521 set s_vaddr here. If string_byte_count remains 4, set it back to
3522 0, and only write strings out if there are some. Call
3523 fill_section before do_relocs_for and do_linenos_for.
3524 (obj_coff_section): Handle optional quoted second argument giving
3525 section characteristics.
3526 (obj_coff_bss): Added to handle .bss.
3527 (obj_coff_ident): Added to handle .ident (puts string in .comment

3547 (do_scrub_next_char): For \", return " not '.
3548 (symbol_chars): Now const.
3550 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3551 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3553 * config/obj-coff.h: Don't use #elif.
3555 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3556 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

3583 using ZERO_BASED_SEGMENTS.
3584 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
3585 never set segment address for SEG_E2 (.bss) and don't write out
3586 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3587 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3588 definitions, and don't merge tags with non-tags. Check for .bf
3589 rather than just checking whether the second character is b and
3590 the third character is f.
3591 (obj_coff_val): gcc can generate values which we don't handle
3592 correctly; discard information for now, since it only affects the
3593 debugging information.

3595 (yank_symbols): Don't merge labels.
3596 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3779 constant will not fit in an immediate field.
3780 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

3800 so widening works consistently.
3802 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
3804 * version.c: Put conditional "const" before version_string, not

3807 * app.c (do_scrub_next_char): Need double-\ before `000' to show
3808 printed rep of null character.
3810 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)

3815 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
3817 * Support for i386-sysv.
3818 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
3819 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
3820 be used to set them all to zero as was done before.
3821 (fill_section): segment addresses now set in write_object_file.
3822 (fill_section): Don't set STYP_NOLOAD for .bss section.
3823 (fixup_segment): 386 uses strange common symbol format.
3824 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
3825 compatibility with SVR3.2 linker.
3826 * configure.in: i386-sysv and i386-sco use coffbfd.

3838 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
3839 support for C source listings. (obj_coff_endef): look in the right
3840 part of the symbol for the symbol name
3842 * tc-m68k.c (get_num): make it work for all segments, not just the
3845 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

3856 * tc-z8k.c: lots of bug fixes
3858 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
3860 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
3861 #elif, since it is not supported by old compilers.
3862 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
3863 couple of expressions in tc-m68k.c.
3865 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3867 * read.c (cons): If NO_RELOC is defined, use it.
3869 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
3871 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
3873 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
3874 local labels to start with a .) and set REGISTER_PREFIX to %.
3875 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

3893 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
3894 sections starting from zero, rather than making them consecutive.
3895 This makes subsequent reloc calculations easier, esp if the object
3896 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
3897 allocate lcomm in .data rather than in .bss. It seems that some
3898 tools can't cope with a non-zero sized bss before linkage.
3900 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3902 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

3924 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
3926 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
3927 .word is < -32768 or > 32767. The -J flag causes the error to be
3928 ignored. This is to catch over-sized switches generated by gcc on
3929 systems which don't support the broken .word hack.
3930 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
3931 write.c (fixup_segment): check for signed .word overflow if
3932 WARN_SIGNED_OVERFLOW_WORD.

3951 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
3953 * input-scrub.c (input_scrub_push): call input_file_begin, not
3955 messages.c (as_perror): print ": " between the passed in error and
3956 the strerror, like perror does.
3958 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

3961 From Steve Chamberlain:
3962 Makefile.in: Handle m68*-*-coff*.
3963 read.c, read.h: add mult argument to s_space
3965 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
3966 Motorola and MIT syntax; gas can now assemble either type of
3968 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

3976 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
3978 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
3981 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3983 * Makefile.in (LIBS): Include opcode library.

4008 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4010 * config/tc-m68k.c (init_table): Now const. Always include 68851
4011 data, so that "bc" is available to 68040 cache instructions.
4012 Added "tt0", "tt1", and 68ec030 variants.
4013 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4014 (enum _register): Added TT0, TT1.
4015 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4016 line number correctly in "internal error" messages. Don't print
4017 architecture-mismatch message for operand errors.
4019 From Colin Smith (colin@wrs.com):
4020 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4021 than install_operand.

4042 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4043 has already been formatted (but may still contain %-characters).
4046 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4048 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4049 written with indirection on the last two operands, which can be
4050 either data or address registers. Added a new operand type 'r'
4051 which accepts either register type. Added '(' to notend stuff in
4052 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

4071 their not having symbols associated.
4073 * tc-i960.c (norelax, instrument_branches): Default initializer is

4279 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
4280 calc the base of relocs correctly.
4281 * tc-a29k.c (parse_operand): allow expressions to be in any section.
4283 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
4285 * as.c, write.c: use -K rather than -k for the broken word warning
4288 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
4290 * Makefile.in: do not print recursion lines.
4292 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4294 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
4296 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4298 * write.c (write_object_file): For b.out format, round up section
4299 start addresses to match required alignment.
4301 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4303 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4304 where gcc looks for it.
4306 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4308 * Makefile.in: Changed some lines to be less confusing for some
4311 * input-file.c: Conditionalize on _IOFBF, not VMS.
4313 * read.c, write.c: Change a series of ifdef/elif to
4314 ifdef/else/ifdef etc.
4316 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
4318 * symbols.c (fb_label_init): fix sizeof to memset.
4320 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
4322 * Makefile.in: install the man page.
4324 * Makefile.in: pass down MAKEINFO explicitly on info.
4326 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
4328 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4330 * flonum-const.c: renamed flonum-konst.c to stop dos name
4333 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
4335 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
4336 tc-m68k.h to te-sun3.h.
4338 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
4340 * configure.in: vxworks68 gets te-sun3.h.
4342 * expr.c: remove limitation that local_labels_dollar or
4343 local_labels_fb must be < 10.
4345 * symbols.c: remove local_labels_dollar, replace with a function
4346 interface for a sparse array. All users adjusted.
4348 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
4350 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4352 * doc/Makefile.in: commented out line for building as-all.texinfo.
4355 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
4357 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
4359 * Makefile.in: added check target.
4361 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4363 * Makefile.in: added tooldir and program_prefix.
4365 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
4367 * write.{c,h} (fix_new): Make these declarations consistent.
4369 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
4371 * Makefile.in (strerror.o): Add rule so that broken Sun make can
4374 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4376 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4378 * expr.c (operand): if can't work out what sort of operand it is,
4379 then look through FLT_CHARS for a hint.
4381 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4383 * Makefile.in, configure.in: removed traces of namesubdir,
4384 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4385 copyrights to '92, changed some from Cygnus to FSF.
4387 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4388 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4389 copyrights to '92, changed some from Cygnus to FSF.
4391 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4393 * expr.c: If an expression is single comma, then return with
4394 SEG_ABSENT rather than an error - since the sparc front end does
4395 really strange things with things like fbge,a
4397 * as.h: include bfd.h if using many sections
4398 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4399 local labels didn't work.
4400 * listing.c (list_symbol_table): don't core dump when there's no
4402 * write.c, write.h: call fix_new with the right number of args on
4404 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4407 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4409 * app.c: MRI compatibility - allow single quote to start a string.
4410 * as.c: fix typo recently introduced.
4411 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4412 * expr.c: Much rewriting, to accomodate MRI syntax for
4413 expressions. Also easier to read now.
4414 * listing.c: Put back defuns
4415 * read.c: modified to accept MRI syntax, put back listing pseudo
4416 ops so that an assembler built with NO_LISTING ignores list ops
4418 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4419 machine is a SPARC or a 29K.
4420 * config/obj-aout.c: added s_sect pseudo op
4421 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4422 fill in the timestamp.
4423 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4424 anymore, define all the relocs which the tc-<x> bit will use so we
4425 can translate from them to the coff types.
4426 * config/tc-a29k.c: reloc_type isn't ane enum any more
4427 * config/tc-m68k.c: Added NO_RELOC definition.
4429 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4431 * Makefile.in: put header files before C source for TAGS; remove
4432 references to non-existent syscalls.h.
4434 * read.c, write.c subsegs.c: back out the .bss changes.
4436 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4438 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4442 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4444 * symbols.c (local_label_name): symbols now start with ^A.
4446 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4447 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4448 generate these sections. .align: will use NOP_OPCODE or 0
4449 for padding. This is just for being nice to the
4452 * expr.c (operand): changed to generate local label "\001L0"
4453 starting with a ^A so that it is recognized as a local label.
4455 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4457 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4458 i/o opcodes - inb, inw, outb and outw. string manipulation with
4459 att syntax - scmp, slod, smov, ssca, ssto.
4461 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4462 to just after .file .
4464 In obj_crawl_symbol_chain() where it tries to put the external
4465 symbols apart, with the condition:
4466 (!S_IS_DEFINED(symbolP) &&
4467 !S_IS_DEBUG(symbolP) &&
4468 !SF_GET_STATICS(symbolP))
4469 it was moving too many symbols out. So I switch it back to the
4471 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4473 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4474 so that we don't use the F_RELFLG which make the linker complain
4475 that somebody has stripped the relocation info.
4477 Also, the AIX ld program require that the relocation table
4478 is sorted by r_vaddr like the standard ATT assembler does.
4480 [he also changed the sizeof(struct ...)'s into the coff
4481 style FOOSZ macros. I'm not sure this is right, but I can't
4482 remember why. xoxorich.]
4484 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4486 * Makefile.in, configure.in, doc: use the doc. Build it, install
4489 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4491 * read.c: white space and comments only.
4493 * configure.in: use the new atof-ns32.c for ns32k.
4495 * write.c: comment change only.
4497 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4498 aren't yet integrated.
4500 * tc-i860.[hc]: blew off the dust. Something must still be done
4501 about conflicting relocation types.
4503 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4506 * tc-i960.c, tc-sparc.c: white space and comments only.
4508 * tc-a29k.h: delete duplicate macro definition.
4510 * new file atof-ns32k.c copied from hack's last unreleased gas.
4512 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4514 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4517 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4518 ChangeLog's prior to this are sketchy at best. I have logs.
4519 They just aren't ChangeLogs.
