* 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.

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.

available only with SSE2. Change the MMX additions introduced by SSE

instructions by their now designated identifier (since combining i686
and 3DNow! does not really imply 3DNow!A).

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,

movsx, movzx, and movd. Adjust floating point operations for the above

actually meant are already gone.

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
