end-sanitize-am33
* config/tc-mn10300.c (mn10300_insert_operand): Do not hardcode the
shift amount for a repeated operand. The shift amount for the
repeated copy comes from the size of the operand.

defaults go unmodified. Replaced $f4/$f5 with $fp[45], as the
original `ld.d' had. Find `ld.s'.

characters in it as LEX_IS_SYMBOL_COMPONENT.

IgnoreDataSize to IgnoreSize as they are used for address size as
well as data size.

32-bit mode, similarly addr16/data16 and variants.
* config/tc-i386.c: REPNE renamed to REPNE_PREFIX_OPCODE, and

(md_begin): Rewrite without obstacks. Remove prefix hash table
handling. Rewrite lexical table handling.
(i386_print_statistics): Don't print prefix statistics.
(md_assemble): Rewrite instruction parser so that line is not
converted to lower case. Don't do a hash_find for prefixes,
instead recognise them via opcode modifier.

(prefix_entry): Remove.
* config/tc-i386.h (PREFIX_SEPERATOR): Don't define.
* config/tc-i386.c (PREFIX_SEPARATOR): Define here instead, using
'\\' in case where comment_chars contains '/'.
* config/tc-i386.c (MATCH): Ensure given operand and template
match for JumpAbsolute. Makes e.g. `ljmp table(%ebx)' invalid;
you must write `ljmp *table(%ebx)'.
From H.J. Lu <hjl@gnu.org>:
* config/tc-i386.c (BFD_RELOC_16, BFD_RELOC_16_PCREL): Define
as 0 ifndef BFD_ASSEMBLER.
(md_assemble): Allow immediate operands without suffix or
other reg operand to default in size to the current code size.

index_reg const.
(add_prefix): Change parameter from char to int.
* config/tc-i386.h (Ugh): Define opcode modifier.

CONSISTENT_REGISTER_MATCH macros to check register types more
thoroughly. Check for illegal suffix/operand combinations
when matching insns with operands. Handle new `s' suffix, and
associated FloatMF opcode modifier for float insns with memory
operands.
* config/tc-i386.h (FloatMF): Define new opcode modifier.
(No_sSuf, No_bSuf, No_wSuf, No_lSuf): Likewise.

more thorough. Remove Abs8,16,32. Change occurrences of Mem to
AnyMem, the better to grep.
(pi): Remove Abs.
(i386_operand): Don't set Mem bits in i.types[this_operand] when
given a memory operand. Don't set Abs bits either.
(type_names): Remove Mem*, Abs*.
* config/tc-i386.h (Mem8, Mem16, Mem32, Abs8, Abs16, Abs32): Don't
define opcode_modifiers as these cases are handled by Disp8,
Disp16, Disp32 and suffix checks.
(COMES_IN_BOTH_DIRECTIONS): Remove.
(FloatR): Define. It's OK to share the bit with ReverseRegRegmem.
* config/tc-i386.c (md_assemble): Don't emit operand size prefix
if IgnoreDataSize modifier given. Remove ShortformW modifier
test. Add test for ShortForm in W base_opcode modification.
Merge Seg2ShortForm and Seg3ShortForm code.
* config/tc-i386.h (ShortFormW): Remove.
(IgnoreDataSize): Define.
* gas/m68k/operands.s: For all pc relative addresses change tstl
to pea since the former does not allow pcrel on m68000. Do not
make label foo global, so that references to it can be relaxed on
ELF targets.
* gas/m68k/operands.d, gas/m68k/op68000.d: Updated.
* config/tc-i386.c (END_STRING_AND_SAVE): Protect arguments of
macros and enclose in do while(0).
(RESTORE_END_STRING): Likewise.
(md_assemble): Add one to printed operand number so we start
from 1 not 0. Add some more gettext invocations.
(i386_operand): Fix `%%s' -> `%%%s'. Inc printed operand
number here too.

DATA_PREFIX, SEG_PREFIX): Define.
* config/tc-i386.c (struct _i386_insn): Remove wait_prefix field.
(check_prefix): Remove function.
(add_prefix): New function. Add prefix to i.prefix as well as
doing checks.
(md_assemble): Changes for add_prefix. Remove hack for wait
prefix, instead always output prefixes in fixed order. Test
for jcxz/loop when selecting between word & dword operations,
and add address size prefix rather than operand size prefix.
Remove operand -> address size hack when emitting jcxz/loop.
(i386_operand): Remove O_Absent check as it's done in expr.
* config/tc-m68k.c (md_estimate_size_before_relax): Add more calls
to relaxable_symbol to prevent references to external symbol from
being relaxed.
Wed Jun 3 14:10:36 1998 Ian Lance Taylor <ian@cygnus.com>
* config/tc-m68k.c (relaxable_symbol): If TARGET_OS is "elf", all
symbols are relaxable.
* macro.c (macro_mri_mode): New function.
* macro.h (macro_mri_mode): Declare.
* read.c (s_mri): Call macro_mri_mode when switching in and out of
MRI mode.
