They're the only exception to there generally being no mix of register
kinds possible in an insn operand template, and there being two bits per
operand for their representation is also quite wasteful, considering the
low number of uses. Fold both bits and deal with the little bit of
fallout.
Also take the liberty and drop dead code trying to set REX_B: No segment
register has RegRex set on it.
Additionally I was quite surprised that PUSH/POP with the permitted
segment registers is not covered by the test cases. Add the missing
pieces.

Old (<= 2.8.1) versions of gcc generate broken fsubp, fsubrp, fdivp and
fdivrp instructions. Assembler translates them to correct ones with a
warning:
[hjl@gnu-cfl-1 gas]$ cat x.s
fsubp %st(3),%st
[hjl@gnu-cfl-1 gas]$ gcc -c x.s
x.s: Assembler messages:
x.s:1: Warning: translating to `fsubp %st,%st(3)'
[hjl@gnu-cfl-1 gas]$
This patch removes support for old (<= 2.8.1) versions of gcc:
[hjl@gnu-cfl-1 gas]$ ./as-new -o x.o x.s
x.s: Assembler messages:
x.s:1: Error: operand type mismatch for `fsubp'
[hjl@gnu-cfl-1 gas]$

(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.

* gas/i386/i386.exp: Execute new tests intelbad and intelok.
* gas/i386/intelbad.[sl]: New test to check for various things not
permitted in Intel mode.
* gas/i386/intel.d, gas/i386/opcode.d, gas/i386/x86-64-opcode.d:
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.

2004-11-04 Jan Beulich <jbeulich@novell.com>
* i386.h (sldx_Suf): Remove.
(FP, l_FP, sl_FP, x_FP): Don't imply IgnoreSize.
(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.
opcodes/
2004-11-04 Jan Beulich <jbeulich@novell.com>
* i386-dis.c (Eq, Edqw, indirEp, Gdq, I1): Define.
(indirEb): Remove.
(Mp): Use f_mode rather than none at all.
(t_mode, dq_mode, dqw_mode, f_mode, const_1_mode): Define. t_mode
replaces what previously was x_mode; x_mode now means 128-bit SSE
operands.
(dis386): Make far jumps and calls have an 'l' prefix only in AT&T
mode. movmskpX's, pextrw's, and pmovmskb's first operands are Gdq.
pinsrw's second operand is Edqw.
(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.
(OP_E): Handle new *_mode values. Correct pointer specifications for
memory operands. Consolidate output of index register.
(OP_G): Handle new *_mode values.
(OP_I): Handle const_1_mode.
(OP_ESreg, OP_DSreg): Generate pointer specifications. Indicate
respective opcode prefix bits have been consumed.
(OP_EM, OP_EX): Provide some default handling for generating pointer
specifications.
