2004-11-04 Jan Beulich <jbeulich@novell.com>
* config/tc-i386.c (set_intel_syntax): Allow % in symbol names when
intel syntax and no register prefix, allow $ in symbol names when
intel syntax.
(set_16bit_gcc_code_flag): Replace literal 'l' by LONG_MNEM_SUFFIX.
(intel_float_operand): Add fourth return value indicating math control
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

permitted in Intel mode.

Adjust for change to segment register store.
* gas/i386/intelok.[sd]: New test to check various Intel mode specific
things get handled correctly.
* gas/i386/x86_64.[sd]: Remove unsupported constructs referring to
'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.

(q_FP): Define, implying no REX64.
(x_FP, sl_FP): Imply FloatMF.
(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.

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

specified for Intel mode.

memory operands. Consolidate output of index register.
