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.

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

49864cfa6c read.c (s_align_bytes): Properly record alignment.
expr.c (__): Undefine before defining.
as.c (got_sig): Don't return anything; return type might be void.
Whitespace/comment cleanup in frags.c.
Some patches for `-pedantic' or `-fno-common' compilation.
(Some of these changes are from Michael Meissner; see change log.)

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

0069b1f670 These are actually Ken's patches--I told him I'd take move them from
p3 into devo.

	* tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined,
	still accept (but don't require) OPTIONAL_REGISTER_PREFIX before
	the register name.
	* tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not
	M68KCOFF.

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.

25fb44628a Patches from WRS:
Mon Sep 21 14:44:17 1992  Ian Lance Taylor  (ian@cygnus.com)

	* tc-m68k.c (m68k_ip): fixed move16 operand handling, from WRS.

Steve Chamberlain
04b07d16c7 * tc-m68k.c (m68k_ip): An(disp) is not pc relative. 1992-09-18 15:03:59 +00:00
Ian Lance Taylor
3ad9ec6a7b Wed Sep 9 11:10:24 1992 Ian Lance Taylor (ian@cygnus.com)
* tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
	 Motorola and MIT syntax; gas can now assemble either type of
	 file.
	tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
	From Steve Chamberlain:
	m68kcoff.mt: for m68k COFF.
	obj-coffbfd.c: (fixup_mdeps) added
	 (size_section) removed bad sanity check
	 (fill_section) added rs_machine_dependent case
	 (write_object_file) call fixup_mdeps
	 (fixup_segment) set fx_subsy to 0.
	obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
	 handle m68k.
	tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
	 pseudo ops.

e53ab768f4 from p3: +0.0 is a small integer, at least for moveq 1992-09-04 23:25:16 +00:00

4134a793c7 * config/tc-m68k.c (init_table): Now const. Always include 68851
data, so that "bc" is available to 68040 cache instructions.  Added
"tt0", "tt1", and 68ec030 variants.
(md_assemble): Complain if 68000 (only) and 68881 are specified.
(enum _register): Added TT0, TT1.
(m68k_ip, cases '3' and 't'): Handle new operand type codes.  Pass
line number correctly in "internal error" messages.  Don't print
architecture-mismatch message for operand errors.

From Colin Smith (colin@wrs.com):
* config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather than
install_operand.

* tc-m68k.c: use TARGET_CPU to choose default cpu type.

	* te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
	so that we can assemble hand-written libgcc code.

c50140c86b This is for PR 628.
Wed Aug 19 11:20:59 1992  Ian Lance Taylor  (ian@cygnus.com)

	* tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
	written with indirection on the last two operands, which can be
	either data or address registers.  Added a new operand type 'r'
	which accepts either register type.  Added '(' to notend stuff in
	tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
1992-08-19 18:27:48 +00:00
Ken Raeburn
8be74775cd * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
selected architecture, print a message saying so and listing what
processors support it, rather than saying "operands mismatch".
1992-08-15 02:57:12 +00:00
Per Bothner
bec66218fc * tc-m68k.c: ".align N" means align to N-byte boundary *only*
if TN_SUN3; otherwise align to 2**N-byte bounary.

Steve Chamberlain
9e43698e16 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.
1992-08-05 19:05:43 +00:00
John Gilmore
934afcd434 * tc-m68k.c (try_index): Error if index scaling specified and
assembling for an older CPU than a 68020.

This bug was found at Adobe because GAS did not diagnose incorrect
68020 code generated by GCC when compiling for 68010.  We had to debug it
in the target system as failing instructions.
1992-08-05 08:59:10 +00:00
Ken Raeburn
6d27d3a205 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
processor/opcode mismatch, so reword the error message.
        (md_assemble): If no CPU has been set (even if FPU/PMMU
        characteristics have been), default to 68020.  Don't need extra
        quotes around error string.

a933d598b6 * expr.c (expr): allow SEG_BSS in expressions
* read.c (potable): align should be nbytes, not ptwo!
	* write.c (write_object_file): extra glue for new bss attributes
	(relax_segment): SEG_BSS is ok now
	* config/tc-m68k.c (m68k_ip_op): can now parse more @( modes

a1765cf0fe * subsegs.c (subseg_change): allow and handle a change into SEG_BSS.
* tc-m68k.c (m68kip): Fix typo so that only arch's >=68020 do
	pcrel data stuff. (md_estimate_size_before_relax): when relaxing a
	68010 bxx into a bra+6 jmpxx, put the bytes of the jmp opcode into
	the right place. (s_bss): Don't put .bss stuff into SEG_DATA, put
	it into SEG_BSS

* expr.c(expr): allow SEG_REGISTER in expressions.
	* read.c(pseudo_set): register expressions can be the source of a
	set.
	* subsegs.c (subseg_new): Now -R forces all changes to SEG_DATA to
	goto SEG_TEXT (if a.out)
	* write.c (write_object_file): If a.out don't use the old way for
	-R.
	* config/obj-a.out (s_sect): complain if the user tries to use a
	subsegment with a value which might interfere with out -R hackery.
	* config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
	rather than use ugly if tree. (init_regtable): insert register
	names into symbol table.
