1753 empty string case like the HP assembler -- assume a value of
1756 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
1757 standard hpux include files to pick up various function decls.
1759 * config/ho-hppaosf.h: Delete _IO* macros. They are defined in

1773 descriptor information to the BFD symbol.
1774 (md_apply_fix): R_HPPA_ENTRY and R_HPPA_EXIT can never be "applied",

1792 of interest to the linker. ENTRY/EXIT relocations for SOM are
1793 an example of marker relocations.
1794 * write.c (write_relocs): Instead of assuming size of a relocation
1795 is 4 bytes, pick up the size from relocation itself.

1825 pass new argument for i, j and o cases.
1826 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
1827 special handling when generating SVR4 PIC code.

1899 (md_begin): Change into the (possibly modified) text_section.
1900 (pa_parse_space_stmt): Create a new segment/space if create_flag
1901 is true, and the space name is not one of the two predefined spaces.

2047 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
2048 the table, require that the one without bit 0x1000000 set come

2159 * configure.in: Set bfd_gas for all sparc targets. Added facility
2160 for keeping or rejecting configurations still under development;
2161 default is to assume production environment, and reject configs
2162 still being worked on. Mark Elf configurations (except sparc and
2163 i386) as developmental. Deleted cases matching some generic names
2164 in favor of more specific names. (E.g., when we get Alpha

2181 through inclusion of tc-hppa.h. Delete all forward declarations
2182 for functions only used within tc-hppa.c, likewise for structures,
2183 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
2184 conditional code in a few small places.
2186 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
2187 structures, global variables, forward declarations together.

2189 conditional code -- try to group conditional code together
2190 into a few places. Make all functions and variables which
2191 are only used within tc-hppa.c static. PARAMize all functions.
2192 Add comments to functions. Delete unused functions, variables,
2193 #defines, etc. Delete unused members within structures. Delete
2194 ldil;ble hacks -- it is believed they were installed to work
2195 around old gas bugs. Avoid using mixed case for local
2196 functions, variables, and structures. Fix formatting problems
2197 not found by GNU-indent. Add FIXME notices for things which
2198 should be worked on the near future. Delete lots of old
2199 useless (1.36 PA-SOM) code.
2201 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
2202 field of the fixS structure. Needed to build unwind

2272 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
2274 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
2275 ELF, since the ELF object format does not have these type of
2276 relocations. Change the abort into as as_bad and return
2277 BFD_RELOC_NONE to silence compiler warnings.
2278 (md_assemble): Keep track of the instruction size. Allow white
2279 space between the $ and the constant for compatibility with older
2280 gases and other assemblers.
2281 (i386_operand): Skip spaces between $ and expression.
2282 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

3291 * expr.c (expr): Don't let absolute_section override
3292 undefined_section for the return value.
3294 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
3295 pseudo-op with a poc_handler field of NULL, ignore it and treat it
3296 as an instruction instead.

3312 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
3313 case to set obj_format=elf. Must go before i386-*-sysv* case that
3314 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
3315 *-*-solaris case, and move to before *-sysv* case that wants to

3342 * Extensive changes to permit symbols to contain any expression
3343 type and to delay the computation of the expression until the
3344 value is actually needed. This permits setting symbols to values
3345 calculated based on object code size. Expressions were changed to
3346 no longer be in a section, to stop the overloading of segment and
3347 expression type that previously occurred.
3349 * as.c (big_section, pass1_section, diff_section, absent_section):
3351 (expr_section): Added (used for dummy symbols which hold

3435 (previous_section, previous_subsection): New vars.
3436 (obj_elf_section): Save current place in case DWARF code wants us
3437 to pop back to it. Handle unquoted section name as well as quoted
3438 section name. Don't crash on invalid strings.
3439 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and
3442 * config/obj-elf.h: Don't include struc-symbol.h.

3527 (omagic): Removed unused variable.
3529 * Preliminary support for m88k-coff.

3551 sy_resolved and sy_resolving single bit fields.
3552 * symbols.c (symbol_new): Don't initialize sy_forward field.

4716 lines; I don't think that can be done portably.
4717 * config/tc-mips.c (macro): Use $AT if target register is zero in
4718 load instruction, which it can be for a floating point load.

4792 prototypes for all static functions. Moved existing minimal
4793 debugging format support info #ifndef OBJ_ECOFF blocks.

4844 * read.c (s_ignore): Don't declare is_end_of_line. It's
4845 redundant, and triggers a VMS gcc compiler bug.
4847 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4848 current segment as an argument. (Ignored in all cases but VMS.)
4849 All callers and definitions changed.

5191 will swap bytes if needed on a big endian system. Use throughout
5193 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
5194 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
5195 types of malformed stabs. Change parsing algorithm so that we are
5196 more certain of having all of the information that we need on hand.
5197 * obj-vms.c (final_forward_reference): New function, used to help
5198 resolve the data types of as many struct elements as possible
5199 when some part of the struct is not fully defined by the compiler.
5200 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
5202 * obj-vms.c (VMS_write_object_file): Define all vtable psects
5203 as symbols as well in the object file. Look for external functions
5204 that start with "__vt.", and turn them into variables, since the
5205 g++ compiler is incapable of doing this.
5206 * tc-vax.c: Add '1' option for backward compatibility with older GCC
5208 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
5209 * input-scrub.c (as_where): Fix bug where as would crash if we did not

5216 SEG_DATA or SEG_E1 if needed.
5217 (s_lcomm): Likewise with bss_section.
5218 (s_fill): Use memset, not bzero.
5220 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

5242 (big_section, reg_section, pass1_section, diff_section,
5243 absent_section, text_section, data_section, bss_section): If
5244 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
5245 mapping to segT enum values.
5246 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
5247 if these are used or defined, if BFD_ASSEMBLER.
5248 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
5249 subseg_new split into two functions.
5250 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
5252 * as.h (volatile): Don't define if already defined.
5253 (had_errors, had_warnings): Provide prototypes for ANSI C even if
5255 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
5256 declare with format attribute for -Wformat checking.
5258 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
5260 * app.c, config/tc-*.c: Don't include read.h, since it is already
5263 * These are based on patches from Minh Tran-le
5264 <mtranle@paris.intellicorp.com>.
5265 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
5266 obj_format coffbfd and gas_target i386coff for target.
5267 (i[34]86-*-isc*): New host (uses sysv).
5268 * config/i386aix.mt: Removed (no longer used).
5269 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
5271 (LDFLAGS): Added, defined as -shlib.
5272 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
5273 * config/te-sco386.h (LOCAL_LABEL): Don't define.
5274 (DOT_LABEL_PREFIX): Define.
5275 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
5276 name rather than L0\001.
5277 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
5279 * symbols.c, symbols.h (local_bss_counter): Removed.

5288 (size_section): Restored sanity check.
5289 (do_relocs_for): Base section address on s_paddr rather than
5290 computing it. Adjust a29k R_IHIHALF special case to account for
5291 section paddr (used to require paddr to be zero). If there are no
5292 reclos, set s_relptr to 0. Set relocation size in object_headers.
5293 (fill_section): Always set s_vaddr here, removing
5294 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
5295 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
5296 Set STYP_INFO for .comment.

5300 H_{SET,GET}_* macros.
5301 (do_linenos_for): Set lineno size in object_headers.
5302 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
5303 set s_vaddr here. If string_byte_count remains 4, set it back to
5304 0, and only write strings out if there are some. Call
5305 fill_section before do_relocs_for and do_linenos_for.
5306 (obj_coff_section): Handle optional quoted second argument giving
5307 section characteristics.
5308 (obj_coff_bss): Added to handle .bss.
5309 (obj_coff_ident): Added to handle .ident (puts string in .comment

5329 (do_scrub_next_char): For \", return " not '.
5330 (symbol_chars): Now const.
5332 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
5333 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
5335 * config/obj-coff.h: Don't use #elif.
5337 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
5338 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

5367 never set segment address for SEG_E2 (.bss) and don't write out
5368 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
5369 (obj_coff_endef): Don't merge labels or symbols awaiting forward
5370 definitions, and don't merge tags with non-tags. Check for .bf
5371 rather than just checking whether the second character is b and
5372 the third character is f.
5373 (obj_coff_val): gcc can generate values which we don't handle
5374 correctly; discard information for now, since it only affects the
5375 debugging information.

5377 (yank_symbols): Don't merge labels.
5378 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5675 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5676 sections starting from zero, rather than making them consecutive.
5677 This makes subsequent reloc calculations easier, esp if the object
5678 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5679 allocate lcomm in .data rather than in .bss. It seems that some
5680 tools can't cope with a non-zero sized bss before linkage.
5682 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5684 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
5685 throughout. That enum no longer means what we thought it meant.

5706 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5708 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5709 .word is < -32768 or > 32767. The -J flag causes the error to be
5710 ignored. This is to catch over-sized switches generated by gcc on
5711 systems which don't support the broken .word hack.
5712 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5713 write.c (fixup_segment): check for signed .word overflow if
5714 WARN_SIGNED_OVERFLOW_WORD.
5716 * write.c (fixup_segment): fixed missing parens in expression
5717 checking for byte or word overflow.

5743 From Steve Chamberlain:
5744 Makefile.in: Handle m68*-*-coff*.
5745 read.c, read.h: add mult argument to s_space
5747 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5748 Motorola and MIT syntax; gas can now assemble either type of

5758 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5760 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5763 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5765 * Makefile.in (LIBS): Include opcode library.

5792 * config/tc-m68k.c (init_table): Now const. Always include 68851
5793 data, so that "bc" is available to 68040 cache instructions.
5794 Added "tt0", "tt1", and 68ec030 variants.
5795 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5796 (enum _register): Added TT0, TT1.
5797 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5798 line number correctly in "internal error" messages. Don't print
5799 architecture-mismatch message for operand errors.

5824 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5825 has already been formatted (but may still contain %-characters).
5828 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5830 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5831 written with indirection on the last two operands, which can be
5832 either data or address registers. Added a new operand type 'r'
5833 which accepts either register type. Added '(' to notend stuff in
5834 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

6165 * Makefile.in, configure.in: removed traces of namesubdir,
6166 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
6167 copyrights to '92, changed some from Cygnus to FSF.
6169 * doc/Makefile.in, doc/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 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6175 * expr.c: If an expression is single comma, then return with
6176 SEG_ABSENT rather than an error - since the sparc front end does
6177 really strange things with things like fbge,a
6179 * as.h: include bfd.h if using many sections
6180 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
6181 local labels didn't work.
6182 * listing.c (list_symbol_table): don't core dump when there's no
6184 * write.c, write.h: call fix_new with the right number of args on
6186 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
6189 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
6191 * app.c: MRI compatibility - allow single quote to start a string.
6192 * as.c: fix typo recently introduced.
6193 * as.h : Don't include aout/reloc.h - it's not right for COFF!
6194 * expr.c: Much rewriting, to accomodate MRI syntax for
6195 expressions. Also easier to read now.
6196 * listing.c: Put back defuns
6197 * read.c: modified to accept MRI syntax, put back listing pseudo
6198 ops so that an assembler built with NO_LISTING ignores list ops
6200 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
6201 machine is a SPARC or a 29K.
6202 * config/obj-aout.c: added s_sect pseudo op
6203 * config/obj-coffbfd.c: lints, set the filehdr flags right and
6204 fill in the timestamp.
6205 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
6206 anymore, define all the relocs which the tc-<x> bit will use so we
6207 can translate from them to the coff types.
6208 * config/tc-a29k.c: reloc_type isn't ane enum any more
6209 * config/tc-m68k.c: Added NO_RELOC definition.
6211 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
6213 * Makefile.in: put header files before C source for TAGS; remove
6214 references to non-existent syscalls.h.
6216 * read.c, write.c subsegs.c: back out the .bss changes.
6218 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
6220 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
6224 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
6226 * symbols.c (local_label_name): symbols now start with ^A.
6228 * read.c, subsegs.c, write.c obj-coff.c: added handling of
6229 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
6230 generate these sections. .align: will use NOP_OPCODE or 0
6231 for padding. This is just for being nice to the
6234 * expr.c (operand): changed to generate local label "\001L0"
6235 starting with a ^A so that it is recognized as a local label.
6237 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
6239 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
6240 i/o opcodes - inb, inw, outb and outw. string manipulation with
6241 att syntax - scmp, slod, smov, ssca, ssto.
6243 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
6244 to just after .file .
6246 In obj_crawl_symbol_chain() where it tries to put the external
6247 symbols apart, with the condition:
6248 (!S_IS_DEFINED(symbolP) &&
6249 !S_IS_DEBUG(symbolP) &&
6250 !SF_GET_STATICS(symbolP))
6251 it was moving too many symbols out. So I switch it back to the
6253 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
6255 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
6256 so that we don't use the F_RELFLG which make the linker complain
6257 that somebody has stripped the relocation info.
6259 Also, the AIX ld program require that the relocation table
6260 is sorted by r_vaddr like the standard ATT assembler does.
6262 [he also changed the sizeof(struct ...)'s into the coff
6263 style FOOSZ macros. I'm not sure this is right, but I can't
6264 remember why. xoxorich.]
6266 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
6268 * Makefile.in, configure.in, doc: use the doc. Build it, install
6271 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
6273 * read.c: white space and comments only.
6275 * configure.in: use the new atof-ns32.c for ns32k.
6277 * write.c: comment change only.
6279 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
6280 aren't yet integrated.
6282 * tc-i860.[hc]: blew off the dust. Something must still be done
6283 about conflicting relocation types.
6285 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
6288 * tc-i960.c, tc-sparc.c: white space and comments only.
6290 * tc-a29k.h: delete duplicate macro definition.
6292 * new file atof-ns32k.c copied from hack's last unreleased gas.
6294 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
6296 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
6299 * nearly everything. flush ChangeLog, package as gas-1.92.1.
6300 ChangeLog's prior to this are sketchy at best. I have logs.
6301 They just aren't ChangeLogs.
6305 version-control: never
