* config/tc-i386.c (optimize_imm): Adjust immediates to only those
permissible for the selected instruction suffix.
(process_suffix): For DefaultSize instructions, suppressing the
guessing of a 'q' suffix if the instruction doesn't support it is
pointless, because only an 'l' suffix can be guessed in this place.
gas/testsuite/

* gas/i386/x86-64-inval.[sl]: Remove sahf/lahf.
include/opcode/
2004-11-25 Jan Beulich <jbeulich@novell.com>
* i386.h: CpuNo64 mov can't reasonably have a 'q' suffix. Moves
to/from test registers are illegal in 64-bit mode. Add missing
NoRex64 to sidt. fxsave/fxrstor now allow for a 'q' suffix
(previously one had to explicitly encode a rex64 prefix). Re-enable
lahf/sahf in 64-bit mode as at least some Athlon64/Opteron steppings
support it there. Add cmpxchg16b as per Intel's 64-bit documentation.
2004-11-23 Jan Beulich <jbeulich@novell.com>

(Cpu3dnowA): Declare.

(cpu_arch): i586 and pentium do not imply MMX. i686 and pentiumpro do
neither imply SSE nor MMX. k6 implies MMX. k6_2 additionally implies
3DNow!. Athlon additionally implies 3DNow!A. Several new
entries (those starting with a dot are for sub-arch specification).
(set_cpu_arch): Handle sub-arch specifications.
(parse_insn): Distinguish between instructions not supported because
of insufficient CPU features and because of 64-bit mode.
* doc/c-i386.texi: Describe enhanced .arch directive.
include/opcode/
2004-11-23 Jan Beulich <jbeulich@novell.com>
* i386.h (i386_optab): paddq and psubq, even in their MMX form, are
available only with SSE2. Change the MMX additions introduced by SSE
and 3DNow!A to CpuMMX2 (rather than CpuMMX). Indicate the 3DNow!A
instructions by their now designated identifier (since combining i686
and 3DNow! does not really imply 3DNow!A).

operations. Make classification more precise.
(md_assemble): Complain if memory operand of mov[sz]x has no size
specified.
(parse_insn): Translate word operands to floating point instructions
operating on integers as well as control instructions to short ones
as expected by AT&T syntax. Translate 'd' suffix to short one only for
floating point instructions operating on non-integer operands.
(match_template): Remove fldcw special case. Adjust q-suffix handling
to permit it on fild/fistp/fisttp in AT&T mode.
(process_suffix): Don't guess DefaultSize insns' suffix from
stackop_size for certain floating point control instructions. Guess
suffix for branch and [ls][gi]dt based on flag_code. Split error
messages for Intel and AT&T syntax, and make the condition more strict
for the former. Adjust suppressing of generation of operand size
overrides.
(intel parser): Allow the full set of MASM operators. Add FWORD, TBYTE,
OWORD, and XMMWORD operand size specifiers (TBYTE replaces XWORD). Add
more error checking.
* config/tc-i386.h (BYTE_PTR WORD_PTR DWORD_PTR QWORD_PTR XWORD_PTR
SHORT OFFSET_FLAT FLAT NONE_FOUND): Remove unused defines.

things get handled correctly.

'high' and 'low' parts of an operand, which the parser previously
accepted while neither telling that it's not supported nor that it
ignored the remainder of the line following these supposed keywords.

(i386_optab): Split reg and mem forms of moving from segment registers
so that the memory forms can ignore the 16-/32-bit operand size
distinction. Adjust a few others for Intel mode. Remove *FP uses from
all non-floating-point instructions. Unite 32- and 64-bit forms of
movsx, movzx, and movd. Adjust floating point operations for the above
changes to the *FP macros. Add DefaultSize to floating point control
insns operating on larger memory ranges. Remove left over comments
hinting at certain insns being Intel-syntax ones where the ones
actually meant are already gone.

(grps): 1-bit shifts' and rotates' second operands are I1. cmpxchg8b's
operand is Eq. movntq's and movntdq's first operands are EM. s[gi]dt,
fldenv, frstor, fsave, fstenv all should also have suffixes in Intel
mode when an operand size override is present or always suffixing.
More instructions will need to be added to this group.
(putop): Handle new macro chars 'C' (short/long suffix selector),
'I' (Intel mode override for following macro char), and 'J' (for
adding the 'l' prefix to far branches in AT&T mode). When an
alternative was specified in the template, honor macro character when
specified for Intel mode.

memory operands. Consolidate output of index register.

(tc_gen_reloc): Support rela relocations and x86_64.
(intel_e09_1): Support QWORD.
* i386.h (i386_optab): Replace "Imm" with "EncImm".
(i386_regtab): Add flags field.
* config/tc-i386.c (intel_e09_1): Only flag as a memory operand if

keep the braces '[' and ']' in the output string.
