Ken Raeburn 9b0da28b13 write.c: Complain about .space or .org moving backwards.
Do generic rs_machine_dependent relaxation only if TC_GENERIC_RELAX_TABLE is
defined.  Use its value as the base of the table, so the actual declaration
can be cpu-specific (and const or not as appropriate).  For other cpus where
this isn't done (the majority), delete md_relax_table altogether.

For machines with WORKING_DOT_WORD, delete md_{short,long}_jump_size.

David MacKenzie f3d817d8b7 * as.c (show_usage): Remove target specific messages;
instead, call md_show_usage.
	(parse_args): Use getopt_long_only.  Take pointers to argc and
	argv.
	(main): Pass parse_args pointers.
	* as.h: Remove 3 variables that are redundant with flagseen.
	* as.c, messages.c: Change their users to use flagseen.

Ian Lance Taylor 4045fbb497 * config/tc-i386.c (md_pseudo_table): Remove "zero".
* config/tc-m88k.c (md_pseudo_table): Likewise.
1994-02-10 16:27:34 +00:00
Ken Raeburn 6868afe647 * as.c (main): Only invoke md_end if it's defined as a macro.
* tc.h (md_end): Don't declare it.
* config/tc-*.[ch] (md_end): Deleted, in cases where it doesn't do anything.
* config/tc-vax.c (vip_end): Deleted null function.
* config/tc-mips.c (md_mips_end): Renamed from md_end.

(md_end): New macro, calls md_mips_end.

* write.c (write_object_file): Don't close output file.
* as.c (main): Close output file (if needed) after calling listing_print, which
should be after calling write_object_file, which sets the frag addresses.

Ken Raeburn c999fd9fc2 * config/tc-vax.c (tc_aout_fix_to_chars): Local variable NBYTES_R_LENGTH now
const.

* config/obj-*.c, config/tc-*.c: Omit superfluous "return" statements at ends
of functions.  Don't check for null return from hash_new, since it won't return
at all if there's no memory available.  Also, check for null return from
hash_insert, rather than zero-length string, as success indicator.

Ken Raeburn bfbfba45ba Lots of changes for:
- sparc[lite]-coff as well as sparc-lynx
 - producing coff (including debug info) under BFD_ASSEMBLER option
 - cleanup of cpu-specific code in non-cpu-specific files
   (especially write.c)
 - providing common code to avoid duplication in cpu-specific files
   (specifically, md_number_to_chars)
 - stylistic changes & misc cleanup

================

* config/tc-sparc.c (tc_gen_reloc): Make adjustment to addend be dependent on
howto fields, not on format flavour.

* struc-symbol.h (struct symbol): New fields sy_obj and sy_tc, defined as types
OBJ_SYMFIELD_TYPE and TC_SYMFIELD_TYPE, if those macros are defined.
* config/obj-coff.h (TC_SYMFIELD_TYPE, OBJ_SYMFIELD_TYPE): Define.
(TARGET_SYMBOL_FIELDS, I960_SYM_FIELDS): Don't define.
(sy_tc, sy_obj): Define so that the fields look like they used to, until all
references get changed.

* write.c (fixup_segment): Lots of variables no longer register.  Reordered
some code for easier reading.
* config/obj-coff.c (obj_coff_dim): dim_index no longer register.  Deleted
superfluous return statement.
(obj_coff_line, obj_coff_size, obj_coff_scl, obj_coff_type, obj_coff_val,
tag_init, tag_insert): Deleted superfluous return statement.
(align, obj_coff_section): Deleted debugging printfs.
* config/tc-i386.c (md_assemble): Discard some register decls.  Use assignment
rather than memcpy to copy template.
(op_hash, reg_hash, prefix_hash): Default C initialization of statics is
sufficient.
* config/tc-sparc.c (print_insn): Array Reloc is now const, and points to
const.

* config/obj-coff.h (TARGET_FORMAT): Only use coff-sparc-lynx if TE_LYNX; use
coff-sparc otherwise.
[USE_NATIVE_HEADERS]: Delete this code; it isn't used.

* write.c (fixup_segment): Call TC_VALIDATE_FIX, if defined, before processing
a fixup.  Call TC_ADJUST_RELOC_COUNT just before returning.  Remove some
i960-coff-specific code.
(TC_ADJUST_RELOC_COUNT): Default to doing nothing.
* config/tc-i960.h (TC_ADJUST_RELOC_COUNT) [OBJ_COFF]: Define.
(i960_validate_fix): Declare.
(TC_VALIDATE_FIX): Define.
* config/tc-i960.c (i960_validate_fix): New function.

* write.c (number_to_chars_littleendian): New function.  Write out bytes in
little endian order, doing size and range checking.
(number_to_chars_bigendian): New function, similar.
* write.h: Declare them.
* config/tc-*.c (md_number_to_chars): Use them.
* config/tc-vax.c (md_apply_fix): Ditto.
* config/tc-i386.c (md_apply_fix): Ditto.

* config/obj-coff.c: Rearranged code for handling line number data.
(line_fsym): Renamed from function_lineoff in BFD_ASSEMBLER case, since the
usage is different from non-BFD_ASSEMBLER case.
(in_function, clear_function, set_function): New macros, to combine some of the
functionality implemented in differnet ways in BFD_ASSEMBLER and non-... code.
Used in other functions that used to check function_lineoff &c.
(obj_emit_lineno): Split into two copies, one for BFD_ASSEMBLER, one for not.
Non-BFD_ASSEMBLER version now has temporary variable to contain char* pointer
pointed to by char** argument.  Always follow CROSS_COMPILE code; easier to
read that way.
(obj_coff_ln): Don't call add_lineno or c_line_new if appline is set.
(obj_coff_endef) [BFD_ASSEMBLER]: Don't do anything special for ".bf", it's
been done elsewhere.
(coff_frob_symbol): If ilne number data is pending, call add_linesym to flush it.
(coff_frob_file): Don't do that here.
* config/obj-coff.h (coff_frob_file): Declare.
(obj_frob_file): Define, to call it.

* config/tc-sparc.h (md_create_short_jump, md_create_long_jump,

Ken Raeburn 9902404797 more null/empty string fixups 1993-10-12 08:45:49 +00:00
Ken Raeburn 43029a8f84 Whitespace/comment cleanup. Use PARAMS in tc-vax.c.
Make various routines return null pointer instead of empty string for
success indication.
1993-09-28 04:47:32 +00:00
K. Richard Pixley 58f3e8a9db * config/tc-m88k.c (get_o6): new function.

	  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.
1993-09-24 19:47:59 +00:00
Ian Lance Taylor 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.
1993-09-13 21:32:07 +00:00
Ian Lance Taylor 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.
1993-07-23 02:55:25 +00:00
Ian Lance Taylor 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.
1993-07-21 17:19:33 +00:00
Ian Lance Taylor 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.

	(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.

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.
1993-07-15 20:23:43 +00:00
Ian Lance Taylor 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

1993-07-15 16:02:21 +00:00
Ian Lance Taylor 332fc09ff0 Clean up some of the obvious m88k bitrot.
It still doesn't actually compile, though.

	places.
1993-03-05 17:10:02 +00:00
Ian Lance Taylor 9a75dc1f76 A bunch of changes to COFF support. See the ChangeLog. 1992-12-30 21:39:51 +00:00
Ken Raeburn 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.
1992-11-23 20:42:33 +00:00
Ian Lance Taylor 587c4264e0 These changes clean things up a bit, and improve Solaris cross
support when using /opt/SUNWspro/SC2.0/acc.

Tue Nov 10 09:50:25 1992  Ian Lance Taylor  (ian@cygnus.com)

	* 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.
