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.

8d6c34a108 (write_relocs): New function, split off from write_contents. Use memset 
instead of bzero.
(write_object_file): Apply write_relocs to each section before applying
write_contents.
 1993-07-19 20:05:16 +00:00
Ken Raeburn
4380166dfa (read_begin): Call obstack_begin with values closer to 1K multiples. 
(read_a_source_file, big_cons, float_cons): Use memcpy instead of bcopy.

Ken Raeburn
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.
(obj_pseudo_table): Handle new pseudos "previous", "2byte", and "4byte".
 1993-07-19 19:49:34 +00:00
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 
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.

9d4dfbf379 fix net-equip pr 2975: tm-m68k.c(m68k_ip): adjust for pc-rel offset before using value, not after 1993-07-19 16:49:01 +00:00
Ian Lance Taylor
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

	(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

	(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.

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
