43029a8f84 Whitespace/comment cleanup. Use PARAMS in tc-vax.c.
Make various routines return null pointer instead of empty string for
success indication.

58f3e8a9db * config/tc-m88k.c (get_o6): new function.
(get_bf, get_cmp, get_cnd, get_cr, get_fcr, get_imm16, get_reg,
	  get_vec9, getval, get_pcr, calcop, match_name): make static and
	  prototype.
	  (s_file): remove extraneous forward decl.
	  (md_begin): add const to retval decl.
	  (calcop): cope with instructions without arguments.  Handle 'o'
	  type argument, the o6 field of the prot insn.
	  (md_estimate_size_before_relax): return a dummy value.

604633aeca * subsegs.c: Renamed non-BFD_ASSEMBLER subseg_new to subseg_set.
Wrote non-BFD_ASSEMBLER subseg_new.  Now subseg_new always takes a
	section name, and subseg_set always takes a segT.  Changed all
	callers as appropriate.
	* config/obj-coffbfd.c 	(change_to_section): Renamed to
	obj_coff_add_segment.  Corrected.  Made callers use subseg_new.
	* config/obj-coffbfd.h (obj_segment_name, obj_add_segment):
	Define.

Also some more gcc warning removal.

cf897ce253 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
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.

8ff6f40e74 * read.c (read_a_source_file): If NO_PSEUDO_DOT is defined, look
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.
	(md_apply_fix): Set fx_offset to the upper 16 bits of the reloc.
	Output the low 16 bits for RELOC_HI16, not the high 16 bits.
	* config/obj-coffbfd.c (do_relocs_for): If TC_M88K, set the
	r_offset field of the reloc to the fixup offset.
	(fixup_segments): If TC_M88K, don't warn about fixup overflows.
	* doc/as.texinfo: Minor updates.

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.
	* subsegs.c (seg_name, subsegs_begin): Changed accordingly.
	* write.c (write_object_file): Ditto.
	* config/obj-aout.c (seg_N_TYPE): Ditto.
	* config/obj-bout.c (seg_N_TYPE): Ditto.
	* config/obj-coff.c (seg_N_TYPE): Ditto.
	* config/obj-coffbfd.c (seg_N_TYPE): Ditto.
	* config/obj-vms.c (seg_N_TYPE): Ditto.

	* expr.h (operatorT): Moved in from expr.c, added some values.
	(expressionS): Added X_op field, removed X_seg field; renamed
	X_subtract_symbol to X_op_symbol.
	* expr.c: Extensive changes to assign expression types rather than
	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.
	* cond.c (s_if): Changed accordingly.
	* read.c (s_lsym, pseudo_set, emit_expr, parse_bitfield_cons,
	parse_repeat_cons, get_segmented_expression,
	get_known_segmented_expression, get_absolute_expression): Ditto.

	process_exit): Ditto.
	* config/tc-hppa.h (STAB_FIXUP, is_DP_relative, is_PC_relative,
	is_complex): Ditto.

	macro_build, macro, my_getExpression): Ditto.  Also removed
	get_optional_absolute_expression; just use get_absolute_expression
	instead.

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.

c978e704a9 * Preliminary support for m88k-coff.
* 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.

332fc09ff0 Clean up some of the obvious m88k bitrot.
It still doesn't actually compile, though.

36d656a6cb * read.h: Define stringer here.
read.c, config/obj-ieee.c, config/obj-tcm88k.c: Not any of these

9a75dc1f76 A bunch of changes to COFF support. See the ChangeLog. 1992-12-30 21:39:51 +00:00

355afbcd8b Ran "indent", for GNU coding style; some code & comments still need fixup.
Removed some unneeded files.

obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
tc-m68k.c (md_assemble): 68000+68881 is okay -- could be emulating.

587c4264e0 These changes clean things up a bit, and improve Solaris cross
support when using /opt/SUNWspro/SC2.0/acc.

	* obj-coffbfd.c (fill_section): set STYP_NOLOAD bit for .bss
	section.

	* atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
	comment_chars, line_comment_chars and line_seperator_chars
	consistently const, and always initialized them.  Included read.h.
