is defined.

1993-07-21 * Extensive changes to permit symbols to contain any expressionIan Lance Taylor19-1158/+1001
type and to delay the computation of the expression until the value is actually needed. This permits setting symbols to values calculated based on object code size. Expressions were changed to no longer be in a section, to stop the overloading of segment and expression type that previously occurred. * as.c (big_section, pass1_section, diff_section, absent_section): Removed. (expr_section): Added (used for dummy symbols which hold intermediate expression values). (perform_an_assembly_pass): Create expr_section, do not create the sections now removed. * as.h (segT): Removed SEG_ABSENT, SEG_PASS1, SEG_BIG, and SEG_DIFFERENCE. Added SEG_EXPR.

1993-07-19various changesKen Raeburn1-0/+26
1993-07-19(write_relocs): New function, split off from write_contents. Use memsetKen Raeburn1-4/+23
instead of bzero. (write_object_file): Apply write_relocs to each section before applying write_contents.
1993-07-19(read_begin): Call obstack_begin with values closer to 1K multiples.Ken Raeburn1-6/+8
(read_a_source_file, big_cons, float_cons): Use memcpy instead of bcopy.
1993-07-19forgot to check this in long ago...Ken Raeburn1-0/+55
1993-07-19(obj_elf_previous): New function.Ken Raeburn1-2/+46
(previous_section, previous_subsection): New vars. (obj_elf_section): Save current place in case DWARF code wants us to pop back to it. Handle unquoted section name as well as quoted section name. Don't crash on invalid strings. (obj_pseudo_table): Handle new pseudos "previous", "2byte", and "4byte".
1993-07-19 * config/tc-m68k.c (m68k_ip_op): Don't decrement strend whenIan Lance Taylor2-2/+4
calculating opP->isiz; this permits the expression size to be determined as well, later on. Fixes PR 2911.
1993-07-19 * expr.c (clean_up_expression): Don't cancel the subtraction ofIan Lance Taylor4-3/+24
undefined symbols. Fixes PR 2997. * read.c (s_data), config/obj-coffbfd.c (obj_coff_data): If -R, switch to text section rather than data section. Fixes PR 2971.
1993-07-19fix net-equip pr 2975: tm-m68k.c(m68k_ip): adjust for pc-rel offset before ↵Ken Raeburn2-2/+8
using value, not after
1993-07-16 * config/tc-hppa.h (tc_frob_label): Define.Ian Lance Taylor2-123/+560
* config/tc-mips.c: Many changes to support simple assembler optimization. (insn_label, prev_insn, prev_prev_insn, dummy_opcode, prev_insn_valid, prev_insn_frag, prev_insn_where, prev_insn_fixp, prev_insn_is_delay_slot): New static variables. (insn_uses_reg, mips_no_prev_insn, mips_emit_delays, mips_align, s_stringer, s_mips_space): New static functions. (mips_define_label): New global function. (md_pseudo_table): For "ascii", "asciz", "asciiz", call s_stringer. Changed argument to float_cons from 0 or 1 to 'f' or 'd'. For "space" call s_mips_space. (md_begin): Call mips_no_prev_insn. (append_insn): Only insert necessary NOP instructions. (macro): Call mips_emit_delays before setting mips_noreorder. Increment and decrement mips_noreorder rather than using save_reorder_condition. Don't bother to use noreorder in M_L_DOB and M_L_DAB, since append_insn will not insert a NOP. (md_atof): Handle floating point numbers correctly for both big and little endian targets. (s_align, s_cons): Call mips_align rather than frag_align. (s_change_seg, s_cons): Call mips_emit_delays. (s_float_cons): Let float_cons do the work. (s_mipsset): Call mips_emit_delays when setting noreorder. * config/tc-mips.h (tc_frob_label): Define to be mips_define_label.
1993-07-16 * read.c (float_cons): Simplified parsing logic. IfIan Lance Taylor3-26/+72
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.
1993-07-16 * config/obj-ecoff.c (ecoff_build_symbols, ecoff_build_procs,Ian Lance Taylor1-0/+7
ecoff_frob_files): Consistently use S_GET_VALUE rather than bfd_asymbol_value. Warn if taking difference of symbols in different segments.

1993-07-15 * config/obj-ecoff.c (ecoff_frob_file): Discard all open scopes,Ian Lance Taylor2-0/+14
with a warning.
1993-07-15 * config/obj-coffbfd.c (fixup_segment): If TC_M88K, don't adjustIan Lance Taylor3-1/+20
by md_pcrel_from if we are relocating against a symbol (we still need md_pcrel_from for a PC relative relocation within the same file). * config/tc-m88k.c (md_pcrel_from): Corrected return value.
1993-07-15Add m88k-coff target Makefile fragment.Ian Lance Taylor2-0/+3

(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 Taylor12-113/+656
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.

1993-07-14 * Changes to keep a full expression as the value of a symbol, notIan Lance Taylor18-880/+1460
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.
