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.

(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

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

* 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
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.
include/opcode/
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.

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.

/* This is tough to explain. We end up with this one if we
|
|
|
|
|
* have operands that look like
|
|
|
|
|
* "_GLOBAL_OFFSET_TABLE_+[.-.L284]". The goal here is to
|
|
|
|
|
* obtain the absolute address of the GOT, and it is strongly
|
|
|
|
|
* preferable from a performance point of view to avoid using
|
|
|
|
|
* a runtime relocation for this. The actual sequence of
|
|
|
|
|
* instructions often look something like:
|
|
|
|
|
*
|
|
|
|
|
* call .L66
|
|
|
|
|
* .L66:
|
|
|
|
|
* popl %ebx
|
|
|
|
|
* addl $_GLOBAL_OFFSET_TABLE_+[.-.L66],%ebx
|
|
|
|
|
*
|
|
|
|
|
* The call and pop essentially return the absolute address
|
|
|
|
|
* of the label .L66 and store it in %ebx. The linker itself
|
|
|
|
|
* will ultimately change the first operand of the addl so
|
|
|
|
|
* that %ebx points to the GOT, but to keep things simple, the
|
|
|
|
|
* .o file must have this operand set so that it generates not
|
|
|
|
|
* the absolute address of .L66, but the absolute address of
|
|
|
|
|
* itself. This allows the linker itself simply treat a GOTPC
|
|
|
|
|
* relocation as asking for a pcrel offset to the GOT to be
|
|
|
|
|
* added in, and the addend of the relocation is stored in the
|
|
|
|
|
* operand field for the instruction itself.
|
|
|
|
|
*
|
|
|
|
|
* Our job here is to fix the operand so that it would add
|
|
|
|
|
* the correct offset so that %ebx would point to itself. The
|
|
|
|
|
* thing that is tricky is that .-.L66 will point to the
|
|
|
|
|
* beginning of the instruction, so we need to further modify
|
|
|
|
|
* the operand so that it will point to itself. There are
|
|
|
|
|
* other cases where you have something like:
|
|
|
|
|
*
|
|
|
|
|
* .long $_GLOBAL_OFFSET_TABLE_+[.-.L66]
|
|
|
|
|
*
|
|
|
|
|
* and here no correction would be required. Internally in
|
|
|
|
|
* the assembler we treat operands of this form as not being
|
|
|
|
|
* pcrel since the '.' is explicitly mentioned, and I wonder
|
|
|
|
|
* whether it would simplify matters to do it this way. Who
|
|
|
|
|
* knows. In earlier versions of the PIC patches, the
|
|
|
|
|
* pcrel_adjust field was used to store the correction, but
|
|
|
|
|
* since the expression is not pcrel, I felt it would be
|
|
|
|
|
* confusing to do it this way. */

constraint within gcc asm statements.
|
|

|
For instance:
|
|
|
|
|
|
|
|
|
|
#define _set_tssldt_desc(n,addr,limit,type) \
|
|
|
|
|
__asm__ __volatile__ ( \
|
|
|
|
|
"movw %w2,%0\n\t" \
|
|
|
|
|
"movw %w1,2+%0\n\t" \
|
|
|
|
|
"rorl $16,%1\n\t" \
|
|
|
|
|
"movb %b1,4+%0\n\t" \
|
|
|
|
|
"movb %4,5+%0\n\t" \
|
|
|
|
|
"movb $0,6+%0\n\t" \
|
|
|
|
|
"movb %h1,7+%0\n\t" \
|
|
|
|
|
"rorl $16,%1" \
|
|
|
|
|
: "=o"(*(n)) : "q" (addr), "ri"(limit), "i"(type))
|
|
|
|
|
|
|
|

This works great except that the output assembler ends
|
|
|
|
|
up looking a bit weird if it turns out that there is
|
|
|
|
|
no offset. You end up producing code that looks like:

done by calling parse_register) and eliminate immediate left recursion

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

* 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

* 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.

* 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.

(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.

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.

OWORD, and XMMWORD operand size specifiers (TBYTE replaces XWORD). Add
more error checking.

* 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.

(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.

(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.

(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.

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.

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.
* 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.
include/opcode/
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.

fldenv, frstor, fsave, fstenv all should also have suffixes in Intel

* 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

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.

* 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.

(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
