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.

	29040.
	(parse_operand): Add argument opt.  If non-zero, don't warn about
	a missing operand.
	(machine_ip): If handling argument type 'I', pass opt as non-zero
	to parse_operand.  Handle new optional operand type 'I'.
	(md_undefined_symbol): Handle special register names (srNN).

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.

	* config/tc-*.c: Add md_shortopts, md_longopts,
	md_longopts_size, md_show_usage.  Change calling convention for
	md_parse_option.  Remove md_parse_long_option.
	* config/tc-ns32k.c: Rename `struct option' to `struct ns32k_option'.

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.
* config/tc-mips.h (md_mips_end): Declare.
(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.

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.

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,
md_estimate_size_before_relax: Define them as macros calling as_fatal.
* config/tc-sparc.c: Don't define them as functions.

Ian Lance Taylor
6121fb06ad * config/tc-a29k.c (md_begin): When opcodes are mashed together in
the table, require that the one without bit 0x1000000 set come
	first.  Require further that it be case 'b' or 'P'.  The a29k
	opcode table already meets these constraints.
	(machine_ip): When handling case 'i' or 'A', make sure that the
	appropriate opcode really exists by looking at the next entry in
	the opcode table.

4f0bccc7d8 Some more gcc lint, and:
* read.c (change_to_section): Removed.  This is now done by
	subseg_new.
	(get_stab_string_offset): Rearranged somewhat.  Create the section
	using subseg_new.  Store the string index in seg_info, rather than
	in a static variable.  Force the first string to be empty.  Use
	frag_more rather than FRAG_APPEND_1_CHAR.
	(s_stab_generic): Rewrote.
	* subsegs.h (segment_info_type): Added stabu union.
	* subsegs.c (subseg_new): Initialize stab_string_size to 0.

	Removed.
	(obj_pseudo_table): Removed desc, stabX and xstabs entries.
	(obj_elf_version): Use subseg_new, not bfd_make_section.  Don't
	set SEC_LOAD for .note section.
	(adjust_stab_sections): Get frag pointer from seg_info, rather
	than looking through frags.
	* config/obj-elf.h (S_{S,G}ET_{OTHER,TYPE,DESC}): Removed.

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.

283dba4ba3 Fix stupid bugs inserted during expression conversion. 1993-07-23 19:17:12 +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.
	(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.

	get_specific, check, insert, md_convert_frag): Ditto.
	* config/tc-hppa.c (the_insn, fix_new_hppa, cons_fix_new_hppa,
	md_assemble, pa_ip, getExpression, getAbsoluteExpression,
	evaluateAbsolute, pa_build_unwind_subspace, pa_entry,
	process_exit): Ditto.
	* config/tc-hppa.h (STAB_FIXUP, is_DP_relative, is_PC_relative,
	is_complex): Ditto.
	* config/tc-i386.c (pe, md_assemble, i386_operand,
	md_estimate_size_before_relax, md_create_long_jump): Ditto.
	* config/tc-i860.c (md_assemble, getExpression, print_insn):
	Ditto.

	Ditto.
	* config/tc-m88k.c (md_assemble, get_imm16, get_pcr,
	md_create_short_jump, md_create_long_jump): Ditto.
	* config/tc-mips.c (md_assemble, append_insn, gp_reference,
	macro_build, macro, my_getExpression): Ditto.  Also removed
	get_optional_absolute_expression; just use get_absolute_expression
	instead.
	* config/tc-ns32k.c (get_addr_mode, evaluate_expr, convert_iif,
	fix_new_ns32k, fix_new_ns32k_exp, cons_fix_new_ns32k): Ditto.

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.

c58dbabf26 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
calc the base of relocs correctly.
	* tc-a29k.c (parse_operand): allow expressions to be in any section.
1992-05-05 01:59:04 +00:00
Steve Chamberlain
c593cf412b * app.c: MRI compatibility - allow single quote to start a string.
* as.c: fix typo recently introduced.
	* as.h : Don't include aout/reloc.h - it's not right for COFF!
	* expr.c: Much rewriting, to accomodate MRI syntax for
	expressions. Also easier to read now.
	* listing.c: Put back defuns
	* read.c: modified to accept MRI syntax, put back listing pseudo
	ops so that an assembler built with NO_LISTING ignores list ops
	rather than pukes.
	* write.c, write.h: fixs - only keep a reloc type in a fix if the target
	machine is a SPARC or a 29K.
	* config/obj-aout.c: added s_sect pseudo op
	* config/obj-coffbfd.c: lints, set the filehdr flags right and
	fill in the timestamp.
	* config/obj-coffbfd.h: Since we don't include aout/reloc.h
	anymore, define all the relocs which the tc-<x> bit will use so we
	can translate from them to the coff types.
	* config/tc-a29k.c: reloc_type isn't ane enum any more
	* config/tc-m68k.c: Added NO_RELOC definition.

Now compiles for sparc aout, 68k aout (MRI and MIT syntax),
29k coff.

So far works as replacement for sparc and 68k /bin/as.
