1744 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
1745 standard hpux include files to pick up various function decls.
1747 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

1759 so GAS can attach unwind descriptor information to a BFD symbol.
1760 * config/tc-hppa.c (fix_new_hppa): If necessary attach unwind
1761 descriptor information to the BFD symbol.
1762 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

1781 an example of marker relocations.
1782 * write.c (write_relocs): Instead of assuming size of a relocation
1783 is 4 bytes, pick up the size from relocation itself.

1813 pass new argument for i, j and o cases.
1814 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

2035 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2036 the table, require that the one without bit 0x1000000 set come

2149 default is to assume production environment, and reject configs
2150 still being worked on. Mark Elf configurations (except sparc and
2151 i386) as developmental. Deleted cases matching some generic names
2152 in favor of more specific names. (E.g., when we get Alpha

2169 through inclusion of tc-hppa.h. Delete all forward declarations
2170 for functions only used within tc-hppa.c, likewise for structures,
2171 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2172 conditional code in a few small places.
2174 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2175 structures, global variables, forward declarations together.

2177 conditional code -- try to group conditional code together
2178 into a few places. Make all functions and variables which
2179 are only used within tc-hppa.c static. PARAMize all functions.
2180 Add comments to functions. Delete unused functions, variables,
2181 #defines, etc. Delete unused members within structures. Delete
2182 ldil;ble hacks -- it is believed they were installed to work
2183 around old gas bugs. Avoid using mixed case for local
2184 functions, variables, and structures. Fix formatting problems
2185 not found by GNU-indent. Add FIXME notices for things which
2186 should be worked on the near future. Delete lots of old
2187 useless (1.36 PA-SOM) code.

2216 a multiple of the section alignment rather than always a
2219 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

2260 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2262 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2263 ELF, since the ELF object format does not have these type of
2264 relocations. Change the abort into as as_bad and return
2265 BFD_RELOC_NONE to silence compiler warnings.
2266 (md_assemble): Keep track of the instruction size. Allow white
2267 space between the $ and the constant for compatibility with older
2268 gases and other assemblers.
2269 (i386_operand): Skip spaces between $ and expression.

3302 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
3303 *-*-solaris case, and move to before *-sysv* case that wants to

3330 * Extensive changes to permit symbols to contain any expression
3331 type and to delay the computation of the expression until the
3332 value is actually needed. This permits setting symbols to values
3333 calculated based on object code size. Expressions were changed to
3334 no longer be in a section, to stop the overloading of segment and
3335 expression type that previously occurred.
3337 * as.c (big_section, pass1_section, diff_section, absent_section):
3339 (expr_section): Added (used for dummy symbols which hold

3423 (previous_section, previous_subsection): New vars.
3424 (obj_elf_section): Save current place in case DWARF code wants us
3425 to pop back to it. Handle unquoted section name as well as quoted
3426 section name. Don't crash on invalid strings.
3427 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
3430 * config/obj-elf.h: Don't include struc-symbol.h.

3515 (omagic): Removed unused variable.
3517 * Preliminary support for m88k-coff.

3539 sy_resolved and sy_resolving single bit fields.
3540 * symbols.c (symbol_new): Don't initialize sy_forward field.

4657 avoid some redefinition complaints on some systems.

4675 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
4677 * Makefile.in: add dvi target; as-$(config).texinfo might live in
4678 srcdir, might be in objdir.

5190 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5191 as symbols as well in the object file. Look for external functions
5192 that start with "__vt.", and turn them into variables, since the
5193 g++ compiler is incapable of doing this.
5194 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5196 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5197 * input-scrub.c (as_where): Fix bug where as would crash if we did not
5198 have the name of the source file yet.
5199 * config/ho-vms.h: define HO_VMS, not HO_VAX.
5201 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
5203 * read.c (s_data): Always use "data_section", since it'll map to
5204 SEG_DATA or SEG_E1 if needed.
5205 (s_lcomm): Likewise with bss_section.
5206 (s_fill): Use memset, not bzero.
5208 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5224 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
5225 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".

5230 (big_section, reg_section, pass1_section, diff_section,
5231 absent_section, text_section, data_section, bss_section): If
5232 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5233 mapping to segT enum values.
5234 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5235 if these are used or defined, if BFD_ASSEMBLER.
5236 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5237 subseg_new split into two functions.
5238 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5240 * as.h (volatile): Don't define if already defined.
5241 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5243 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5244 declare with format attribute for -Wformat checking.
5246 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5248 * app.c, config/tc-*.c: Don't include read.h, since it is already
5251 * These are based on patches from Minh Tran-le
5252 <mtranle@paris.intellicorp.com>.
5253 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5254 obj_format coffbfd and gas_target i386coff for target.
5255 (i[34]86-*-isc*): New host (uses sysv).
5256 * config/i386aix.mt: Removed (no longer used).
5257 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5259 (LDFLAGS): Added, defined as -shlib.
5260 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5261 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5262 (DOT_LABEL_PREFIX): Define.
5263 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5264 name rather than L0\001.
5265 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5267 * symbols.c, symbols.h (local_bss_counter): Removed.
5268 * write.c (write_object_file): bss no longer uses

5276 (size_section): Restored sanity check.
5277 (do_relocs_for): Base section address on s_paddr rather than
5278 computing it. Adjust a29k R_IHIHALF special case to account for
5279 section paddr (used to require paddr to be zero). If there are no
5280 reclos, set s_relptr to 0. Set relocation size in object_headers.
5281 (fill_section): Always set s_vaddr here, removing
5282 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5283 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5284 Set STYP_INFO for .comment.
5285 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
5286 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

5288 H_{SET,GET}_* macros.
5289 (do_linenos_for): Set lineno size in object_headers.
5290 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5291 set s_vaddr here. If string_byte_count remains 4, set it back to
5292 0, and only write strings out if there are some. Call
5293 fill_section before do_relocs_for and do_linenos_for.
5294 (obj_coff_section): Handle optional quoted second argument giving
5295 section characteristics.
5296 (obj_coff_bss): Added to handle .bss.
5297 (obj_coff_ident): Added to handle .ident (puts string in .comment

5300 (fixup_mdeps): Change to segment. Call frag_wane after
5302 (fixup_segment): Explicitly check S_IS_COMMON before making 386
5303 adjustment (already happened only for common symbols, but this is
5305 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

5317 (do_scrub_next_char): For \", return " not '.
5318 (symbol_chars): Now const.
5320 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5321 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5323 * config/obj-coff.h: Don't use #elif.
5325 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5326 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

5353 using ZERO_BASED_SEGMENTS.
5354 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
5355 never set segment address for SEG_E2 (.bss) and don't write out
5356 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5357 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5358 definitions, and don't merge tags with non-tags. Check for .bf
5359 rather than just checking whether the second character is b and
5360 the third character is f.
5361 (obj_coff_val): gcc can generate values which we don't handle
5362 correctly; discard information for now, since it only affects the
5363 debugging information.

5365 (yank_symbols): Don't merge labels.
5366 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5664 sections starting from zero, rather than making them consecutive.
5665 This makes subsequent reloc calculations easier, esp if the object
5666 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5667 allocate lcomm in .data rather than in .bss. It seems that some
5668 tools can't cope with a non-zero sized bss before linkage.
5670 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5672 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
5673 throughout. That enum no longer means what we thought it meant.

5694 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5696 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5697 .word is < -32768 or > 32767. The -J flag causes the error to be
5698 ignored. This is to catch over-sized switches generated by gcc on
5699 systems which don't support the broken .word hack.
5700 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5701 write.c (fixup_segment): check for signed .word overflow if
5702 WARN_SIGNED_OVERFLOW_WORD.

5731 From Steve Chamberlain:
5732 Makefile.in: Handle m68*-*-coff*.
5733 read.c, read.h: add mult argument to s_space
5735 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5736 Motorola and MIT syntax; gas can now assemble either type of
5738 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5748 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5751 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5753 * Makefile.in (LIBS): Include opcode library.

5780 * config/tc-m68k.c (init_table): Now const. Always include 68851
5781 data, so that "bc" is available to 68040 cache instructions.
5782 Added "tt0", "tt1", and 68ec030 variants.
5783 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5784 (enum _register): Added TT0, TT1.
5785 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5786 line number correctly in "internal error" messages. Don't print
5787 architecture-mismatch message for operand errors.
5789 From Colin Smith (colin@wrs.com):
5790 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

5812 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5813 has already been formatted (but may still contain %-characters).
5816 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5818 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5819 written with indirection on the last two operands, which can be
5820 either data or address registers. Added a new operand type 'r'
5821 which accepts either register type. Added '(' to notend stuff in
5822 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6163 * expr.c: If an expression is single comma, then return with
6164 SEG_ABSENT rather than an error - since the sparc front end does
6165 really strange things with things like fbge,a
6167 * as.h: include bfd.h if using many sections
6168 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6169 local labels didn't work.
6170 * listing.c (list_symbol_table): don't core dump when there's no
6172 * write.c, write.h: call fix_new with the right number of args on
6174 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6177 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6179 * app.c: MRI compatibility - allow single quote to start a string.
6180 * as.c: fix typo recently introduced.
6181 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6182 * expr.c: Much rewriting, to accomodate MRI syntax for
6183 expressions. Also easier to read now.
6184 * listing.c: Put back defuns
6185 * read.c: modified to accept MRI syntax, put back listing pseudo
6186 ops so that an assembler built with NO_LISTING ignores list ops
6188 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6189 machine is a SPARC or a 29K.
6190 * config/obj-aout.c: added s_sect pseudo op
6191 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6192 fill in the timestamp.
6193 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6194 anymore, define all the relocs which the tc-<x> bit will use so we
6195 can translate from them to the coff types.
6196 * config/tc-a29k.c: reloc_type isn't ane enum any more
6197 * config/tc-m68k.c: Added NO_RELOC definition.
6199 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6201 * Makefile.in: put header files before C source for TAGS; remove
6202 references to non-existent syscalls.h.
6204 * read.c, write.c subsegs.c: back out the .bss changes.
6206 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6208 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6212 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6214 * symbols.c (local_label_name): symbols now start with ^A.
6216 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6217 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6218 generate these sections. .align: will use NOP_OPCODE or 0
6219 for padding. This is just for being nice to the
6222 * expr.c (operand): changed to generate local label "\001L0"
6223 starting with a ^A so that it is recognized as a local label.
6225 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6227 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6228 i/o opcodes - inb, inw, outb and outw. string manipulation with
6229 att syntax - scmp, slod, smov, ssca, ssto.
6231 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6232 to just after .file .
6234 In obj_crawl_symbol_chain() where it tries to put the external
6235 symbols apart, with the condition:
6236 (!S_IS_DEFINED(symbolP) &&
6237 !S_IS_DEBUG(symbolP) &&
6238 !SF_GET_STATICS(symbolP))
6239 it was moving too many symbols out. So I switch it back to the
6241 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6243 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6244 so that we don't use the F_RELFLG which make the linker complain
6245 that somebody has stripped the relocation info.
6247 Also, the AIX ld program require that the relocation table
6248 is sorted by r_vaddr like the standard ATT assembler does.
6250 [he also changed the sizeof(struct ...)'s into the coff
6251 style FOOSZ macros. I'm not sure this is right, but I can't
6252 remember why. xoxorich.]
6254 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6256 * Makefile.in, configure.in, doc: use the doc. Build it, install
6259 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6261 * read.c: white space and comments only.
6263 * configure.in: use the new atof-ns32.c for ns32k.
6265 * write.c: comment change only.
6267 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6268 aren't yet integrated.
6270 * tc-i860.[hc]: blew off the dust. Something must still be done
6271 about conflicting relocation types.
6273 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6276 * tc-i960.c, tc-sparc.c: white space and comments only.
6278 * tc-a29k.h: delete duplicate macro definition.
6280 * new file atof-ns32k.c copied from hack's last unreleased gas.
6282 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6284 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6287 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6288 ChangeLog's prior to this are sketchy at best. I have logs.
6289 They just aren't ChangeLogs.
6293 version-control: never
