7 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",
8 they are simply markers. Make R_HPPA_UNWIND_* handling OBJ_ELF
10 (pa_build_unwind_subspace): Whole function is OBJ_ELF dependent.
11 (pa_entry): Build a R_HPPA_ENTRY relocation when configured for SOM.
12 (pa_exit): Likewise, but built a R_HPPA_EXIT relocation. Do not
13 build "end-of-function" symbols for SOM, they are not needed.
15 * config/tc-hppa.c (process_exit): Create temporary symbols with
16 correct prefixes so they can be eliminated later.
18 * config/tc-hppa.c (call_info struct): Delete unused "frame" field.

28 is 4 bytes, pick up the size from relocation itself.
29 (fixup_segment): Do not complain that a value is too small for

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

136 pa_segment_to_space. Reset BFD section flags as required by
137 the .subspace directive. Likewise for the section alignment.
138 Pass the current space to update_subspace and create_new_subspace.
139 (pa_spaces_begin): Only use space/subspace aliases if USE_ALIASES
140 is true. When not using aliases, create a BFD section for each
141 subspace encountered. When not using aliases replace the default
142 text, data, and bss segments with new ones.

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

425 Add comments to functions. Delete unused functions, variables,
426 #defines, etc. Delete unused members within structures. Delete
427 ldil;ble hacks -- it is believed they were installed to work
428 around old gas bugs. Avoid using mixed case for local
429 functions, variables, and structures. Fix formatting problems
430 not found by GNU-indent. Add FIXME notices for things which
431 should be worked on the near future. Delete lots of old
432 useless (1.36 PA-SOM) code.

1461 Thu Jul 29 18:38:37 1993 david d `zoo' zuhn (zoo@rtl.cygnus.com)
1463 * config/ho-sunos.h: remove some old function decls that conflict
1464 w/ ANSI, and which weren't needed anyway
1466 Wed Jul 28 16:34:55 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
1468 * config/obj-elf.h (obj_frob_symbol): Renamed from tc_frob_symbol,

1510 are also magic, and have special default flag settings.
1511 (obj_elf_frob_symbol): Since the return value from this function

1575 * Extensive changes to permit symbols to contain any expression
1576 type and to delay the computation of the expression until the
1577 value is actually needed. This permits setting symbols to values
1578 calculated based on object code size. Expressions were changed to
1579 no longer be in a section, to stop the overloading of segment and
1580 expression type that previously occurred.
1582 * as.c (big_section, pass1_section, diff_section, absent_section):
1584 (expr_section): Added (used for dummy symbols which hold

1670 to pop back to it. Handle unquoted section name as well as quoted
1671 section name. Don't crash on invalid strings.
1672 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

1784 sy_resolved and sy_resolving single bit fields.
1785 * symbols.c (symbol_new): Don't initialize sy_forward field.

2850 dependencies are read, not when they are used).
2852 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
2853 a29k .bss section; the mondfe program doesn't like it.

2898 process relocs if there aren't any relocs to process. Avoids
2899 malloc/free bug on SCO too.

2902 avoid some redefinition complaints on some systems.
2903 (const, volatile): Don't need these conditionally defined if we
2904 use CONST and VOLATILE from ansidecl.h.
2905 (seg_name): Use CONST, not const.
2907 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
2909 * config/tc-mips.c: Reindented to GNU standards.

2920 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
2922 * Makefile.in: add dvi target; as-$(config).texinfo might live in

2942 * Makefile.in (targ-cpu.o): Depend on config.h.
2944 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
2946 * app.c (do_scrub_next_char): Added new state, 9, to avoid
2947 dropping a space immediately following an identifier.
2948 * expr.c, write.c: Rewrote assert expressions to not use multiple
2949 lines; I don't think that can be done portably.
2950 * config/tc-mips.c (macro): Use $AT if target register is zero in
2951 load instruction, which it can be for a floating point load.
2953 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

2974 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
2976 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
2977 to be on a single line.

3025 prototypes for all static functions. Moved existing minimal
3026 debugging format support info #ifndef OBJ_ECOFF blocks.

3075 * make-gas.com: Find obstack.obj if it's not in the current
3077 * read.c (s_ignore): Don't declare is_end_of_line. It's
3078 redundant, and triggers a VMS gcc compiler bug.
3080 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3081 current segment as an argument. (Ignored in all cases but VMS.)
3082 All callers and definitions changed.

3378 * config/tc-sparc.c (architecture_requested, warn_on_bump,
3379 md_relax_table): Use default zero initialization.
3380 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3381 latter, instead of selecting with preprocessor conditionals.
3383 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3385 * configure.in: recognise all sparclite variants
3387 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

3393 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3395 * expr.c (operand): If character other than comma or newline is a
3396 logical end-of-line character, use the newline case.
3397 From Eric Youngdale:
3398 (operand): Set X_add_number field for floating-point numbers.
3399 (operand): Treat zero byte as end-of-operand.
3401 * configure.in (per-target): Look for with_bfd_assembler option.
3402 For now, only accept "no", until the merge is done.
3404 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3405 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
3406 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
3407 * read.c: Finish conversion to S_* macros in the VMS only
3408 parts of the program. Add "const" modifier to hex_value.
3409 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
3411 * expr.c: Add "const" modifier to hex_value.
3412 * symbols.c: Finish conversion to S_* macros in the VMS only
3413 parts of the program. Add "const" modifier to
3414 md_[long,short]_jump_size. Remove declaration of const_flag
3415 (which will be declared in obj-vms.h).
3416 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3417 Fix arguments to VMS_write_object_file.
3418 * config-gas.com: New file. Script for VMS systems to set up the
3419 configuration to build gas for VMS, and create config.status.
3420 * make-gas.com: Redone to work with new scheme.
3421 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3423 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
3424 will swap bytes if needed on a big endian system. Use throughout
3426 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3427 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3428 types of malformed stabs. Change parsing algorithm so that we are
3429 more certain of having all of the information that we need on hand.
3430 * obj-vms.c (final_forward_reference): New function, used to help
3431 resolve the data types of as many struct elements as possible
3432 when some part of the struct is not fully defined by the compiler.
3433 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
3435 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3436 as symbols as well in the object file. Look for external functions
3437 that start with "__vt.", and turn them into variables, since the
3438 g++ compiler is incapable of doing this.
3439 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3441 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
3442 * input-scrub.c (as_where): Fix bug where as would crash if we did not
3443 have the name of the source file yet.
3444 * config/ho-vms.h: define HO_VMS, not HO_VAX.
3446 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
3448 * read.c (s_data): Always use "data_section", since it'll map to
3449 SEG_DATA or SEG_E1 if needed.
3450 (s_lcomm): Likewise with bss_section.
3451 (s_fill): Use memset, not bzero.
3453 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

3474 (section_alignment): Declare only if not BFD_ASSEMBLER.
3475 (big_section, reg_section, pass1_section, diff_section,
3476 absent_section, text_section, data_section, bss_section): If
3477 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3478 mapping to segT enum values.
3479 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3480 if these are used or defined, if BFD_ASSEMBLER.
3481 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3482 subseg_new split into two functions.
3483 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3485 * as.h (volatile): Don't define if already defined.
3486 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3488 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3489 declare with format attribute for -Wformat checking.
3491 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3493 * app.c, config/tc-*.c: Don't include read.h, since it is already
3496 * These are based on patches from Minh Tran-le
3497 <mtranle@paris.intellicorp.com>.
3498 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3499 obj_format coffbfd and gas_target i386coff for target.
3500 (i[34]86-*-isc*): New host (uses sysv).
3501 * config/i386aix.mt: Removed (no longer used).
3502 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3504 (LDFLAGS): Added, defined as -shlib.
3505 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3506 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3507 (DOT_LABEL_PREFIX): Define.
3508 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3509 name rather than L0\001.
3510 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3512 * symbols.c, symbols.h (local_bss_counter): Removed.
3513 * write.c (write_object_file): bss no longer uses
3514 local_bss_counter. Pass correct data and bss size to

3521 (size_section): Restored sanity check.
3522 (do_relocs_for): Base section address on s_paddr rather than
3523 computing it. Adjust a29k R_IHIHALF special case to account for
3524 section paddr (used to require paddr to be zero). If there are no
3525 reclos, set s_relptr to 0. Set relocation size in object_headers.
3526 (fill_section): Always set s_vaddr here, removing
3527 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3528 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3529 Set STYP_INFO for .comment.

3533 H_{SET,GET}_* macros.
3534 (do_linenos_for): Set lineno size in object_headers.
3535 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3536 set s_vaddr here. If string_byte_count remains 4, set it back to
3537 0, and only write strings out if there are some. Call
3538 fill_section before do_relocs_for and do_linenos_for.
3539 (obj_coff_section): Handle optional quoted second argument giving
3540 section characteristics.
3541 (obj_coff_bss): Added to handle .bss.
3542 (obj_coff_ident): Added to handle .ident (puts string in .comment

3545 (fixup_mdeps): Change to segment. Call frag_wane after
3547 (fixup_segment): Explicitly check S_IS_COMMON before making 386
3548 adjustment (already happened only for common symbols, but this is
3550 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

3562 (do_scrub_next_char): For \", return " not '.
3563 (symbol_chars): Now const.
3565 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3566 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3568 * config/obj-coff.h: Don't use #elif.
3570 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3571 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
3573 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

3597 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
3598 using ZERO_BASED_SEGMENTS.
3599 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
3600 never set segment address for SEG_E2 (.bss) and don't write out
3601 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3602 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3603 definitions, and don't merge tags with non-tags. Check for .bf
3604 rather than just checking whether the second character is b and
3605 the third character is f.
3606 (obj_coff_val): gcc can generate values which we don't handle
3607 correctly; discard information for now, since it only affects the
3608 debugging information.
3609 (tag_find_or_name): Don't insert tags in the symbol table.
3610 (yank_symbols): Don't merge labels.
3611 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3830 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
3832 * Support for i386-sysv.
3833 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
3834 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
3835 be used to set them all to zero as was done before.

3875 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
3876 #elif, since it is not supported by old compilers.
3877 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
3878 couple of expressions in tc-m68k.c.
3880 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3882 * read.c (cons): If NO_RELOC is defined, use it.

3886 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
3888 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
3889 local labels to start with a .) and set REGISTER_PREFIX to %.
3890 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

3908 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
3909 sections starting from zero, rather than making them consecutive.
3910 This makes subsequent reloc calculations easier, esp if the object
3911 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
3912 allocate lcomm in .data rather than in .bss. It seems that some
3913 tools can't cope with a non-zero sized bss before linkage.
3915 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3917 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

3939 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
3941 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
3942 .word is < -32768 or > 32767. The -J flag causes the error to be
3943 ignored. This is to catch over-sized switches generated by gcc on
3944 systems which don't support the broken .word hack.
3945 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
3946 write.c (fixup_segment): check for signed .word overflow if
3947 WARN_SIGNED_OVERFLOW_WORD.

3966 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
3968 * input-scrub.c (input_scrub_push): call input_file_begin, not
3970 messages.c (as_perror): print ": " between the passed in error and
3971 the strerror, like perror does.

3976 From Steve Chamberlain:
3977 Makefile.in: Handle m68*-*-coff*.
3978 read.c, read.h: add mult argument to s_space
3980 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
3981 Motorola and MIT syntax; gas can now assemble either type of

3993 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
3996 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
3998 * Makefile.in (LIBS): Include opcode library.

4023 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4025 * config/tc-m68k.c (init_table): Now const. Always include 68851
4026 data, so that "bc" is available to 68040 cache instructions.
4027 Added "tt0", "tt1", and 68ec030 variants.
4028 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4029 (enum _register): Added TT0, TT1.
4030 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4031 line number correctly in "internal error" messages. Don't print
4032 architecture-mismatch message for operand errors.

4057 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4058 has already been formatted (but may still contain %-characters).
4061 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4063 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4064 written with indirection on the last two operands, which can be
4065 either data or address registers. Added a new operand type 'r'
4066 which accepts either register type. Added '(' to notend stuff in
4067 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

4174 ancient or broken compilers.
4176 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
4177 processor/opcode mismatch, so reword the error message.

4292 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4294 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
4295 calc the base of relocs correctly.
4296 * tc-a29k.c (parse_operand): allow expressions to be in any section.
4298 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
4300 * as.c, write.c: use -K rather than -k for the broken word warning
4303 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
4305 * Makefile.in: do not print recursion lines.
4307 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)

4311 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4313 * write.c (write_object_file): For b.out format, round up section
4314 start addresses to match required alignment.
4316 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4318 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4319 where gcc looks for it.
4321 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4323 * Makefile.in: Changed some lines to be less confusing for some
4326 * input-file.c: Conditionalize on _IOFBF, not VMS.
4328 * read.c, write.c: Change a series of ifdef/elif to
4329 ifdef/else/ifdef etc.
4331 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
4333 * symbols.c (fb_label_init): fix sizeof to memset.

4343 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4345 * flonum-const.c: renamed flonum-konst.c to stop dos name
4348 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
4350 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
4351 tc-m68k.h to te-sun3.h.
4353 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
4355 * configure.in: vxworks68 gets te-sun3.h.
4357 * expr.c: remove limitation that local_labels_dollar or
4358 local_labels_fb must be < 10.
4360 * symbols.c: remove local_labels_dollar, replace with a function
4361 interface for a sparse array. All users adjusted.
4363 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
4365 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4367 * doc/Makefile.in: commented out line for building as-all.texinfo.
4370 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
4372 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

4384 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
4386 * Makefile.in (strerror.o): Add rule so that broken Sun make can
4389 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4391 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4393 * expr.c (operand): if can't work out what sort of operand it is,
4394 then look through FLT_CHARS for a hint.
4396 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4398 * Makefile.in, configure.in: removed traces of namesubdir,
4399 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4400 copyrights to '92, changed some from Cygnus to FSF.
4402 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4403 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4404 copyrights to '92, changed some from Cygnus to FSF.
4406 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4408 * expr.c: If an expression is single comma, then return with
4409 SEG_ABSENT rather than an error - since the sparc front end does
4410 really strange things with things like fbge,a
4412 * as.h: include bfd.h if using many sections
4413 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4414 local labels didn't work.
4415 * listing.c (list_symbol_table): don't core dump when there's no
4417 * write.c, write.h: call fix_new with the right number of args on
4419 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4422 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4424 * app.c: MRI compatibility - allow single quote to start a string.
4425 * as.c: fix typo recently introduced.
4426 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4427 * expr.c: Much rewriting, to accomodate MRI syntax for
4428 expressions. Also easier to read now.
4429 * listing.c: Put back defuns
4430 * read.c: modified to accept MRI syntax, put back listing pseudo
4431 ops so that an assembler built with NO_LISTING ignores list ops
4433 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4434 machine is a SPARC or a 29K.
4435 * config/obj-aout.c: added s_sect pseudo op
4436 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4437 fill in the timestamp.
4438 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4439 anymore, define all the relocs which the tc-<x> bit will use so we
4440 can translate from them to the coff types.
4441 * config/tc-a29k.c: reloc_type isn't ane enum any more
4442 * config/tc-m68k.c: Added NO_RELOC definition.
4444 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4446 * Makefile.in: put header files before C source for TAGS; remove
4447 references to non-existent syscalls.h.
4449 * read.c, write.c subsegs.c: back out the .bss changes.
4451 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4453 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4457 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4459 * symbols.c (local_label_name): symbols now start with ^A.
4461 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4462 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4463 generate these sections. .align: will use NOP_OPCODE or 0
4464 for padding. This is just for being nice to the
4467 * expr.c (operand): changed to generate local label "\001L0"
4468 starting with a ^A so that it is recognized as a local label.
4470 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4472 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4473 i/o opcodes - inb, inw, outb and outw. string manipulation with
4474 att syntax - scmp, slod, smov, ssca, ssto.
4476 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4477 to just after .file .
4479 In obj_crawl_symbol_chain() where it tries to put the external
4480 symbols apart, with the condition:
4481 (!S_IS_DEFINED(symbolP) &&
4482 !S_IS_DEBUG(symbolP) &&
4483 !SF_GET_STATICS(symbolP))
4484 it was moving too many symbols out. So I switch it back to the
4486 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4488 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4489 so that we don't use the F_RELFLG which make the linker complain
4490 that somebody has stripped the relocation info.
4492 Also, the AIX ld program require that the relocation table
4493 is sorted by r_vaddr like the standard ATT assembler does.
4495 [he also changed the sizeof(struct ...)'s into the coff
4496 style FOOSZ macros. I'm not sure this is right, but I can't
4497 remember why. xoxorich.]
4499 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4501 * Makefile.in, configure.in, doc: use the doc. Build it, install
4504 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4506 * read.c: white space and comments only.
4508 * configure.in: use the new atof-ns32.c for ns32k.
4510 * write.c: comment change only.
4512 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4513 aren't yet integrated.
4515 * tc-i860.[hc]: blew off the dust. Something must still be done
4516 about conflicting relocation types.
4518 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4521 * tc-i960.c, tc-sparc.c: white space and comments only.
4523 * tc-a29k.h: delete duplicate macro definition.
4525 * new file atof-ns32k.c copied from hack's last unreleased gas.
4527 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4529 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4532 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4533 ChangeLog's prior to this are sketchy at best. I have logs.
4534 They just aren't ChangeLogs.
