1993-07-23 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find aIan Lance Taylor1-0/+2
pseudo-op with a poc_handler field of NULL, ignore it and treat it as an instruction instead. * config/tc-m88k.c (md_pseudo_table): Add "set" with a NULL poc_handler field.
1993-07-21 * read.c (read_a_source_file): If NO_PSEUDO_DOT is defined, lookIan Lance Taylor1-3/+12
up opcodes as pseudo-ops even if they don't start with '.'. * config/tc-m88k.h (NO_PSEUDO_DOT): Define. * config/tc-m88k.c (md_assemble): Removed special pseudo-op handling.

1993-07-14 * Removed sy_forward and replaced it with an undefined expressionIan Lance Taylor1-2/+8
as the value of a symbol. * struc-symbol.h (struct symbol): Removed sy_forward field. Added sy_resolved and sy_resolving single bit fields. * symbols.c (symbol_new): Don't initialize sy_forward field. (resolve_symbol_value): New function to adjust symbol value by fragment address, using recursion to resolve forward symbols. * symbols.h: Added prototype for new function. * read.c (pseudo_set): Set symbolP->sy_value to an undefined expression rather than setting symbolP->sy_forward. * write.c (write_object_file): Use resolve_symbol_value on symbols, keeping the common case (the old behaviour) inline. * config/obj-aout.c (obj_aout_frob_symbol): Removed sy_forward handling (subsumed by write.c change). * config/obj-coff.c, config/obj-coffbfd.c (obj_coff_val): Set sy_value rather than sy_forward. * config/obj-coffbfd.c (obj_coff_endef, yank_symbols): Check expression segment rather than sy_forward.

1993-05-27read.c (s_align_bytes): Properly record alignment.Ken Raeburn1-0/+2
expr.c (__): Undefine before defining. as.c (got_sig): Don't return anything; return type might be void. Whitespace/comment cleanup in frags.c. Some patches for `-pedantic' or `-fno-common' compilation. (Some of these changes are from Michael Meissner; see change log.)
1993-05-27 * app.c (do_scrub_begin): Let line_comment_chars overrideIan Lance Taylor1-28/+86
comment_chars. (do_scrub_next_char): If a line comment character is not at the start of a line, treat it as a comment character if it is one. For a CPP line comment use pseudo-op .appline rather than .line. * input-scrub.c (logical_input_line): Make int rather than unsigned.

1993-01-04fix goof from last changeKen Raeburn1-0/+4
1993-01-04(s_data): Use "data_section"; it'll map to SEG_DATA or SEG_E1 if appropriate,Ken Raeburn1-178/+39

* app.c, config/tc-*.c: Don't include read.h, since it is already included by as.h. * These are based on patches from Minh Tran-le <mtranle@paris.intellicorp.com>. * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use obj_format coffbfd and gas_target i386coff for target. (i[34]86-*-isc*): New host (uses sysv). * config/i386aix.mt: Removed (no longer used). * config/mh-i386aix (RANLIB): Use true rather than /bin/true. (MINUS_G): Removed. (LDFLAGS): Added, defined as -shlib. * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine. * config/te-sco386.h (LOCAL_LABEL): Don't define. (DOT_LABEL_PREFIX): Define. * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label name rather than L0\001. * read.c (s_lcomm): Make a frag in SEG_BSS rather than using local_bss_counter. * symbols.c, symbols.h (local_bss_counter): Removed. * write.c (write_object_file): bss no longer uses local_bss_counter. Pass correct data and bss size to VMS_write_object_file. * config/obj-vms.c (VMS_write_object_file): Accept bss size as argument, rather than using local_bss_counter. * config/tc-m88k.c (s_bss): Don't use local_bss_counter. * config/tc-sparc.c (s_reserve): Don't use local_bss_counter. * config/obj-coffbfd.c (had_lineno, had_reloc): Removed. (size_section): Restored sanity check. (do_relocs_for): Base section address on s_paddr rather than computing it. Adjust a29k R_IHIHALF special case to account for section paddr (used to require paddr to be zero). If there are no reclos, set s_relptr to 0. Set relocation size in object_headers. (fill_section): Always set s_vaddr here, removing ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set NOLOAD for i386 .bss, because it confuses the SVR3 native linker. Set STYP_INFO for .comment. (coff_header_append): Use object headers and H_{SET,GET}_* macros. Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER. (crawl_symbols): Handle 8 character section name correctly. Use H_{SET,GET}_* macros. (do_linenos_for): Set lineno size in object_headers. (write_object_file): Use H_{SET,GET}_* macros. Don't bother to set s_vaddr here. If string_byte_count remains 4, set it back to 0, and only write strings out if there are some. Call fill_section before do_relocs_for and do_linenos_for. (obj_coff_section): Handle optional quoted second argument giving section characteristics. (obj_coff_bss): Added to handle .bss. (obj_coff_ident): Added to handle .ident (puts string in .comment section). (obj_coff_lcomm): Put common symbols in .bss, not .data. (fixup_mdeps): Change to segment. Call frag_wane after md_convert_frag. (fixup_segment): Explicitly check S_IS_COMMON before making 386 adjustment (already happened only for common symbols, but this is clearer). * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define. * config/tc-i386.c (s_bss): Don't use if I386COFF. (md_pseudo_table): Ignore .optim and .noopt. (tc_coff_sizemachdep): New function. * config/tc-i386.h (REVERSE_SORT_RELOCS): Undef, for SVR3 compatibility. (LOCAL_LABEL): Removed definition. (DOT_LABEL_PREFIX): Defined.

* listing.c: Call xmalloc, not malloc; don't declare malloc. * Changes to support SCO 3.2v4: * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or SEG_BSS, fill with NOP_OPCODE. * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS. * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not using ZERO_BASED_SEGMENTS. (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but never set segment address for SEG_E2 (.bss) and don't write out SEG_E2 contents. Set .init and .fini sections to STYP_TEXT. (obj_coff_endef): Don't merge labels or symbols awaiting forward definitions, and don't merge tags with non-tags. Check for .bf rather than just checking whether the second character is b and the third character is f. (obj_coff_val): gcc can generate values which we don't handle correctly; discard information for now, since it only affects the debugging information. (tag_find_or_name): Don't insert tags in the symbol table. (yank_symbols): Don't merge labels. (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is already defined. Fill subsegments with NOP_OPCODE, not 0. Don't set segment address if ZERO_BASED_SEGMENTS. (obj_coff_section): Accept and ignore a trailing quoted string, as used in AT&T i386 syntax. (fixup_segment): Take segment as argument. On the i386, adjust PC relative addends by the segment vaddr. * tc-i386.h: Define SUB_SEGMENT_ALIGN. * tc-a29k.h: Define ZERO_BASED_SEGMENTS. * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.
1992-11-23Ran "indent", for GNU coding style; some code & comments still need fixup.Ken Raeburn1-1455/+1658
Removed some unneeded files. configure.in: Don't look for te-386bsd.h, which doesn't exist...
1992-09-09Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)Ian Lance Taylor1-1/+7

* expr.c(expr): allow SEG_REGISTER in expressions. * read.c(pseudo_set): register expressions can be the source of a set. * subsegs.c (subseg_new): Now -R forces all changes to SEG_DATA to goto SEG_TEXT (if a.out) * write.c (write_object_file): If a.out don't use the old way for -R. * config/obj-a.out (s_sect): complain if the user tries to use a subsegment with a value which might interfere with out -R hackery. * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table rather than use ugly if tree. (init_regtable): insert register names into symbol table.
