1993-07-16 * read.c (float_cons): Simplified parsing logic. IfIan Lance Taylor1-2/+3
REPEAT_CONS_EXPRESSIONS is defined, accept a repeat count. * symbols.c (colon): Rather than a special case for TC_HPPA, use new macro tc_frob_label.
1993-07-15 * Preliminary support for m88k-coff.Ian Lance Taylor1-0/+15
* configure.in (m88k-*-coff*): New target. Use coffbfd and m88kcoff. * config/m88kcoff.mt: New file. * read.c (lex_type): New macro LEX_AT to set lex type of '@'. (pseudo_set): Handle difference of symbols in different fragments by saving the entire expression as the value of the symbol. * symbols.c (resolve_symbol_value): Resolve difference expressions. * config/obj-coffbfd.c (obj_pseudo_table): If TC_M88K, accept "sdef" as a synonym for "def". * config/obj-coffbfd.h: If TC_M88K, include coff/m88k.h and set TARGET_FORMAT. (S_IS_LOCAL): Any symbol which includes \001 in the name is local. * config/tc-m88k.c, config/tc-m88k.h: Numerous changes to bring m88k port up to date, and to add COFF support.
1993-07-14 * Removed sy_forward and replaced it with an undefined expressionIan Lance Taylor1-2/+48
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. (yank_symbols): Use resolve_symbol_value. (crawl_symbols): Removed extra pass over symbols. * config/obj-aout.c, config/obj-bout.c, config/obj-coff.c, config/obj-vms.c (obj_crawl_symbol_chain): Removed extra pass over symbols which handled sy_forward; use resolve_symbol_value instead. * config/obj-coff.h, config/obj-coffbfd.h (obj_frob_forward_symbol): Define. * config/obj-elf.c (obj_elf_stab_generic): Check expression segment rather than sy_forward. * config/obj-vms.c (VMS_Check_For_Main): Don't initialize sy_forward; do initialize sy_resolved and sy_resolving. * config/tc-hppa.h (STAB_FIXUP): Use sy_value, not sy_forward.
1993-07-14 * Changes to keep a full expression as the value of a symbol, notIan Lance Taylor1-15/+22
just a longword: * struc-symbol.h: New field sy_value. * as.h: Include expr.h before struc-symbol.h. * expr.h: Use struct symbol rather than symbolS. * symbols.c (S_GET_VALUE, S_SET_VALUE): Rewrote to retrieve value of sy_value field; compile unconditionally, not just if BFD_ASSEMBLER. * symbols.h: Compile S_{SG}ET_VALUE prototypes unconditionally. * write.c (write_object_file): Set BFD symbol value to gas symbol value. * config/obj-aout.h, config/obj-bout.h, config/obj-coff.h, config/obj-coffbfd.h, config/obj-generic.h, config/obj-vms.h (S_GET_VALUE, S_SET_VALUE): Removed macro definitions. * config/obj-ieee.c (S_GET_VALUE, S_SET_VALUE): Removed. * config/obj-coff.h, obj-coffbfd.h: Rewrote several macros to use S_GET_VALUE rather than ost_entry.n_value. * config/obj-aout.c (obj_symbol_to_chars), config/obj-bout.c (obj_symbol_to_chars), config/obj-coff.c (obj_symbol_to_chars), config/obj-coffbfd.c (symbol_to_chars): Get value to write out using S_GET_VALUE--don't assume it is already set. * config/obj-ieee.c (do_symbols): Set BFD symbol value to gas symbol value. * config/obj-vms.c (various): Don't assign directly to S_GET_VALUE; use S_SET_VALUE instead.
1993-07-07 * symbols.c (fb_label_instance, fb_label_instance_inc): Don't dumpIan Lance Taylor1-13/+22
core just because somebody uses a label before it is defined.
1993-07-07* symbols.c (symbol_new): Symbol value is type valueT.Ken Raeburn1-192/+293
(S_SET_VALUE, S_GET_VALUE): Likewise. (S_IS_*): Specify int return type explicitly. * symbols.h (symbol_new, S_GET_VALUE, S_SET_VALUE): Fixed prototypes.

* 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.
1992-11-23Ran "indent", for GNU coding style; some code & comments still need fixup.Ken Raeburn1-442/+775
Removed some unneeded files. configure.in: Don't look for te-386bsd.h, which doesn't exist...
1992-02-13force all files to end in "/* end of filename"K. Richard Pixley1-1/+1
1992-02-13White space and comments only. The devo tree prior to this delta isK. Richard Pixley1-268/+266
tagged as "vanilla" for your convenience. There are also some comment changes.
1992-01-24 * symbols.c(colon): if a symbol is being multiply defined as exactlySteve Chamberlain1-4/+9
the same value, then don't cause a fatal error. This fixes P00000616 - where a def _foo= . followed by foo: is seen.
