1757 empty string case like the HP assembler -- assume a value of
1760 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
1761 standard hpux include files to pick up various function decls.
1763 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

1796 of interest to the linker. ENTRY/EXIT relocations for SOM are
1797 an example of marker relocations.
1798 * write.c (write_relocs): Instead of assuming size of a relocation
1799 is 4 bytes, pick up the size from relocation itself.

1829 pass new argument for i, j and o cases.
1830 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
1831 special handling when generating SVR4 PIC code.

2051 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2052 the table, require that the one without bit 0x1000000 set come

2164 for keeping or rejecting configurations still under development;
2165 default is to assume production environment, and reject configs
2166 still being worked on. Mark Elf configurations (except sparc and
2167 i386) as developmental. Deleted cases matching some generic names
2168 in favor of more specific names. (E.g., when we get Alpha

2185 through inclusion of tc-hppa.h. Delete all forward declarations
2186 for functions only used within tc-hppa.c, likewise for structures,
2187 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2188 conditional code in a few small places.
2190 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2191 structures, global variables, forward declarations together.

2193 conditional code -- try to group conditional code together
2194 into a few places. Make all functions and variables which
2195 are only used within tc-hppa.c static. PARAMize all functions.
2196 Add comments to functions. Delete unused functions, variables,
2197 #defines, etc. Delete unused members within structures. Delete
2198 ldil;ble hacks -- it is believed they were installed to work
2199 around old gas bugs. Avoid using mixed case for local
2200 functions, variables, and structures. Fix formatting problems
2201 not found by GNU-indent. Add FIXME notices for things which
2202 should be worked on the near future. Delete lots of old
2203 useless (1.36 PA-SOM) code.

2278 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2279 ELF, since the ELF object format does not have these type of
2280 relocations. Change the abort into as as_bad and return
2281 BFD_RELOC_NONE to silence compiler warnings.
2282 (md_assemble): Keep track of the instruction size. Allow white
2283 space between the $ and the constant for compatibility with older
2284 gases and other assemblers.
2285 (i386_operand): Skip spaces between $ and expression.

3295 * expr.c (expr): Don't let absolute_section override
3296 undefined_section for the return value.
3298 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
3299 pseudo-op with a poc_handler field of NULL, ignore it and treat it
3300 as an instruction instead.

3316 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
3317 case to set obj_format=elf. Must go before i386-*-sysv* case that
3318 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
3319 *-*-solaris case, and move to before *-sysv* case that wants to

3346 * Extensive changes to permit symbols to contain any expression
3347 type and to delay the computation of the expression until the
3348 value is actually needed. This permits setting symbols to values
3349 calculated based on object code size. Expressions were changed to
3350 no longer be in a section, to stop the overloading of segment and
3351 expression type that previously occurred.
3353 * as.c (big_section, pass1_section, diff_section, absent_section):
3355 (expr_section): Added (used for dummy symbols which hold

3439 (previous_section, previous_subsection): New vars.
3440 (obj_elf_section): Save current place in case DWARF code wants us
3441 to pop back to it. Handle unquoted section name as well as quoted
3442 section name. Don't crash on invalid strings.
3443 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
3446 * config/obj-elf.h: Don't include struc-symbol.h.

3531 (omagic): Removed unused variable.
3533 * Preliminary support for m88k-coff.

3555 sy_resolved and sy_resolving single bit fields.
3556 * symbols.c (symbol_new): Don't initialize sy_forward field.

4718 dropping a space immediately following an identifier.
4719 * expr.c, write.c: Rewrote assert expressions to not use multiple
4720 lines; I don't think that can be done portably.
4721 * config/tc-mips.c (macro): Use $AT if target register is zero in
4722 load instruction, which it can be for a floating point load.

4796 prototypes for all static functions. Moved existing minimal
4797 debugging format support info #ifndef OBJ_ECOFF blocks.

4848 * read.c (s_ignore): Don't declare is_end_of_line. It's
4849 redundant, and triggers a VMS gcc compiler bug.
4851 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4852 current segment as an argument. (Ignored in all cases but VMS.)
4853 All callers and definitions changed.

5191 * make-gas.com: Redone to work with new scheme.
5192 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
5194 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
5195 will swap bytes if needed on a big endian system. Use throughout
5197 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5198 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5199 types of malformed stabs. Change parsing algorithm so that we are
5200 more certain of having all of the information that we need on hand.
5201 * obj-vms.c (final_forward_reference): New function, used to help
5202 resolve the data types of as many struct elements as possible
5203 when some part of the struct is not fully defined by the compiler.
5204 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5206 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5207 as symbols as well in the object file. Look for external functions
5208 that start with "__vt.", and turn them into variables, since the
5209 g++ compiler is incapable of doing this.
5210 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5212 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5213 * input-scrub.c (as_where): Fix bug where as would crash if we did not

5220 SEG_DATA or SEG_E1 if needed.
5221 (s_lcomm): Likewise with bss_section.
5222 (s_fill): Use memset, not bzero.
5224 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5246 (big_section, reg_section, pass1_section, diff_section,
5247 absent_section, text_section, data_section, bss_section): If
5248 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5249 mapping to segT enum values.
5250 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5251 if these are used or defined, if BFD_ASSEMBLER.
5252 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5253 subseg_new split into two functions.
5254 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5256 * as.h (volatile): Don't define if already defined.
5257 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5259 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5260 declare with format attribute for -Wformat checking.
5262 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5264 * app.c, config/tc-*.c: Don't include read.h, since it is already
5267 * These are based on patches from Minh Tran-le
5268 <mtranle@paris.intellicorp.com>.
5269 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5270 obj_format coffbfd and gas_target i386coff for target.
5271 (i[34]86-*-isc*): New host (uses sysv).
5272 * config/i386aix.mt: Removed (no longer used).
5273 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5275 (LDFLAGS): Added, defined as -shlib.
5276 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5277 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5278 (DOT_LABEL_PREFIX): Define.
5279 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5280 name rather than L0\001.
5281 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5283 * symbols.c, symbols.h (local_bss_counter): Removed.
5284 * write.c (write_object_file): bss no longer uses

5292 (size_section): Restored sanity check.
5293 (do_relocs_for): Base section address on s_paddr rather than
5294 computing it. Adjust a29k R_IHIHALF special case to account for
5295 section paddr (used to require paddr to be zero). If there are no
5296 reclos, set s_relptr to 0. Set relocation size in object_headers.
5297 (fill_section): Always set s_vaddr here, removing
5298 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5299 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5300 Set STYP_INFO for .comment.

5304 H_{SET,GET}_* macros.
5305 (do_linenos_for): Set lineno size in object_headers.
5306 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5307 set s_vaddr here. If string_byte_count remains 4, set it back to
5308 0, and only write strings out if there are some. Call
5309 fill_section before do_relocs_for and do_linenos_for.
5310 (obj_coff_section): Handle optional quoted second argument giving
5311 section characteristics.
5312 (obj_coff_bss): Added to handle .bss.
5313 (obj_coff_ident): Added to handle .ident (puts string in .comment

5333 (do_scrub_next_char): For \", return " not '.
5334 (symbol_chars): Now const.
5336 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5337 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5339 * config/obj-coff.h: Don't use #elif.
5341 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5342 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

5371 never set segment address for SEG_E2 (.bss) and don't write out
5372 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5373 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5374 definitions, and don't merge tags with non-tags. Check for .bf
5375 rather than just checking whether the second character is b and
5376 the third character is f.
5377 (obj_coff_val): gcc can generate values which we don't handle
5378 correctly; discard information for now, since it only affects the
5379 debugging information.

5381 (yank_symbols): Don't merge labels.
5382 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5679 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5680 sections starting from zero, rather than making them consecutive.
5681 This makes subsequent reloc calculations easier, esp if the object
5682 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5683 allocate lcomm in .data rather than in .bss. It seems that some
5684 tools can't cope with a non-zero sized bss before linkage.
5686 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5688 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
5689 throughout. That enum no longer means what we thought it meant.

5710 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5712 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5713 .word is < -32768 or > 32767. The -J flag causes the error to be
5714 ignored. This is to catch over-sized switches generated by gcc on
5715 systems which don't support the broken .word hack.
5716 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5717 write.c (fixup_segment): check for signed .word overflow if
5718 WARN_SIGNED_OVERFLOW_WORD.
5720 * write.c (fixup_segment): fixed missing parens in expression
5721 checking for byte or word overflow.

5747 From Steve Chamberlain:
5748 Makefile.in: Handle m68*-*-coff*.
5749 read.c, read.h: add mult argument to s_space
5751 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5752 Motorola and MIT syntax; gas can now assemble either type of

5762 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5764 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5767 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5769 * Makefile.in (LIBS): Include opcode library.

5794 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5796 * config/tc-m68k.c (init_table): Now const. Always include 68851
5797 data, so that "bc" is available to 68040 cache instructions.
5798 Added "tt0", "tt1", and 68ec030 variants.
5799 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5800 (enum _register): Added TT0, TT1.
5801 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5802 line number correctly in "internal error" messages. Don't print
5803 architecture-mismatch message for operand errors.
5805 From Colin Smith (colin@wrs.com):
5806 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5807 than install_operand.

5828 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5829 has already been formatted (but may still contain %-characters).
5832 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5834 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5835 written with indirection on the last two operands, which can be
5836 either data or address registers. Added a new operand type 'r'
5837 which accepts either register type. Added '(' to notend stuff in
5838 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6167 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
6169 * Makefile.in, configure.in: removed traces of namesubdir,
6170 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6171 copyrights to '92, changed some from Cygnus to FSF.
6173 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
6174 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6175 copyrights to '92, changed some from Cygnus to FSF.
6177 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6179 * expr.c: If an expression is single comma, then return with
6180 SEG_ABSENT rather than an error - since the sparc front end does
6181 really strange things with things like fbge,a
6183 * as.h: include bfd.h if using many sections
6184 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6185 local labels didn't work.
6186 * listing.c (list_symbol_table): don't core dump when there's no
6188 * write.c, write.h: call fix_new with the right number of args on
6190 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6193 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6195 * app.c: MRI compatibility - allow single quote to start a string.
6196 * as.c: fix typo recently introduced.
6197 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6198 * expr.c: Much rewriting, to accomodate MRI syntax for
6199 expressions. Also easier to read now.
6200 * listing.c: Put back defuns
6201 * read.c: modified to accept MRI syntax, put back listing pseudo
6202 ops so that an assembler built with NO_LISTING ignores list ops
6204 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6205 machine is a SPARC or a 29K.
6206 * config/obj-aout.c: added s_sect pseudo op
6207 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6208 fill in the timestamp.
6209 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6210 anymore, define all the relocs which the tc-<x> bit will use so we
6211 can translate from them to the coff types.
6212 * config/tc-a29k.c: reloc_type isn't ane enum any more
6213 * config/tc-m68k.c: Added NO_RELOC definition.
6215 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6217 * Makefile.in: put header files before C source for TAGS; remove
6218 references to non-existent syscalls.h.
6220 * read.c, write.c subsegs.c: back out the .bss changes.
6222 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6224 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6228 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6230 * symbols.c (local_label_name): symbols now start with ^A.
6232 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6233 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6234 generate these sections. .align: will use NOP_OPCODE or 0
6235 for padding. This is just for being nice to the
6238 * expr.c (operand): changed to generate local label "\001L0"
6239 starting with a ^A so that it is recognized as a local label.
6241 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6243 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6244 i/o opcodes - inb, inw, outb and outw. string manipulation with
6245 att syntax - scmp, slod, smov, ssca, ssto.
6247 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6248 to just after .file .
6250 In obj_crawl_symbol_chain() where it tries to put the external
6251 symbols apart, with the condition:
6252 (!S_IS_DEFINED(symbolP) &&
6253 !S_IS_DEBUG(symbolP) &&
6254 !SF_GET_STATICS(symbolP))
6255 it was moving too many symbols out. So I switch it back to the
6257 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6259 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6260 so that we don't use the F_RELFLG which make the linker complain
6261 that somebody has stripped the relocation info.
6263 Also, the AIX ld program require that the relocation table
6264 is sorted by r_vaddr like the standard ATT assembler does.
6266 [he also changed the sizeof(struct ...)'s into the coff
6267 style FOOSZ macros. I'm not sure this is right, but I can't
6268 remember why. xoxorich.]
6270 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6272 * Makefile.in, configure.in, doc: use the doc. Build it, install
6275 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6277 * read.c: white space and comments only.
6279 * configure.in: use the new atof-ns32.c for ns32k.
6281 * write.c: comment change only.
6283 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6284 aren't yet integrated.
6286 * tc-i860.[hc]: blew off the dust. Something must still be done
6287 about conflicting relocation types.
6289 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6292 * tc-i960.c, tc-sparc.c: white space and comments only.
6294 * tc-a29k.h: delete duplicate macro definition.
6296 * new file atof-ns32k.c copied from hack's last unreleased gas.
6298 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6300 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6303 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6304 ChangeLog's prior to this are sketchy at best. I have logs.
6305 They just aren't ChangeLogs.
6309 version-control: never
