pseudo-op with a poc_handler field of NULL, ignore it and treat it
	as an instruction instead.

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

5ac34ac37e * Extensive changes to permit symbols to contain any expression
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.
	(SEG_NORMAL): Corresponding changes.

	sections and to simplify the parsing.
	* write.c (fix_new_internal): New static function.
	(fix_new): Removed sub_symbol argument.
	(fix_new_exp): New function, takes expression argument.
	* write.h: Prototype changes for fix_new and fix_new_exp.

7c05f0ec40 (obj_elf_previous): New function.
(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.

Ian Lance Taylor
ce2ad89aca * config/tc-m68k.c (m68k_ip_op): Don't decrement strend when
calculating opP->isiz; this permits the expression size to be
	determined as well, later on.

Fixes PR 2911.
1993-07-19 19:13:30 +00:00
Ian Lance Taylor
ffffc8fb5c * expr.c (clean_up_expression): Don't cancel the subtraction of

becfe05e61 * config/tc-hppa.h (tc_frob_label): Define.
* 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.

1993-07-16 16:26:41 +00:00
Ian Lance Taylor
1e9cf56586 * read.c (float_cons): Simplified parsing logic. If
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 16:26:03 +00:00
Ian Lance Taylor
04acd059ee * config/obj-ecoff.c (ecoff_build_symbols, ecoff_build_procs,
ecoff_frob_files): Consistently use S_GET_VALUE rather than
	bfd_asymbol_value.  Warn if taking difference of symbols in
	different segments.
1993-07-16 15:58:08 +00:00
Ian Lance Taylor
cb441b387e * config/tc-m88k.c (omagic): Removed unused variable. 1993-07-15 22:16:39 +00:00

Ian Lance Taylor
2368ec638a * config/obj-coffbfd.c (fixup_segment): If TC_M88K, don't adjust
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.

* 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.

	fragment address, using recursion to resolve forward symbols.

	* 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

	(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

	* expr.h: Use struct symbol rather than symbolS.

	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.
