For the flavors having a GPR operand VEX.W is ignored outside of 64-bit
mode. The mnemonic should therefore not be KMOVQ.
|
|
PEXTR{B,W} and PINSR{B,W}, just like for AVX512BW, are WIG, no matter
that the SDM uses a nonstandard description of that fact.
PEXTRD, even with EVEX.W set, ignores that bit outside of 64-bit mode,
just like its AVX counterpart.

In the course of folding their patterns (possible now that the pointless
and partly even bogus VecESize are no longer in the way) I've noticed
that vcvt*2usi, other than their vcvt*2si counterparts, don't allow for
any suffixes. As that is supposedly intentional, make the disassembler
consistently omit suffixes for all to-scalar-int conversion insns.
|
|
The wrong placement of the Load attribute in the templates prevented
this from working. The disassembler also didn't handle this consistently
with other similar dual-encoding insns.

"fi*" typically come in two (loads/stores: three) flavors, distinguished
by the suffix. Don't omit the 's' one when disassembling.
|
|
Despite EVEX encodings not being available in real and VM86 modes,
16-bit addressing still needs to be handled properly for 16-bit
protected mode as well as 16-bit addressing in 32-bit mode. Neither
should displacements be dropped silently by the assembler, nor should
the disassembler fail to correctly scale 8-bit displacements.
|
|
Make the assembler recognize UD0, supporting only the newer form
expecting a ModR/M byte.
Make assembler and disassembler properly emit / expect a ModR/M byte for
UD1.
For the testsuite, as arch-4 already tests all UDn, avoid producing a
huge delta for other tests using UD2B by making them use UD2 instead.
|
|
While commits 9889cbb14e ("Check invalid mask registers") and
abfcb414b9 ("X86: Ignore REX_B bit for 32-bit XOP instructions") went a
bit into the right direction, this wasn't quite enough:
- VEX.vvvv has its high bit ignored
- EVEX.vvvv has its high bit ignored together with EVEX.v'
- the high bits of {,E}VEX.vvvv should not be prematurely zapped, to
allow proper checking of them when the fields has to hold al ones
- when the high bits of an immediate specify a register, bit 7 is
ignored
|
|
VEX.W may be legitimately set (and is then ignored by the CPU) for
non-64-bit code. Don't print 64-bit register names in such a case, by
utilizing that REX_W would never be set for non-64-bit code, and that
it is being set from VEX.W by generic decoding.
A test for this is going to be introduced in the next patch of this
series.
|
|
The low four bits of an immediate being set when the high bits specify a
fourth register operand is not a problem: CPUs ignore these bits rather
than raising #UD. Take care of incrementing codep in OP_EX_VexW()
instead.
|
|
Matching up with the assembler, which already supports them.

Since the NOTRACK prefix is no longer required to be the last prefix
before the REX prefix, restriction on the NOTRACK prefix position is
removed from assembler as well as disassembler. Assembler encodes the
NOTRACK prefix the same way as the DS segment register, which places
it before other prefixes. Disassembler displays prefixes in the order
they appear.

The instructions are not documented in the Intel SDM but are documented
in the AMD APM as an alias to the group 2, ModRM.reg == 4 variant.
Both AMD and Intel CPUs execute the C[0-1] and D[0-3] instructions as
expected, i.e., like the /4 aliases:
#include <stdio.h>
int main(void)
{
int a = 2;
printf ("a before: %d\n", a);
asm volatile(".byte 0xd0,0xf0" /* SHL %al */
: "+a" (a));
printf("a after : %d\n", a);
return 0;
}
$ ./a.out
a before: 2
a after : 4

With the changes done in previous patches, print_insn_XXX functions
don't have to be external visible out of opcodes, because both gdb
and objdump select disassemblers through a single interface.
This patch moves these print_insn_XXX declarations from

added by this patch.

Just like REX.W affects operand size of the implicit rAX/rDX inputs to
PCMPESTR{I,M}, VEX.W does for VPCMPESTR{I,M}. Allow Q or L suffixes on
the instructions.
Similarly the disassembler needs to be adjusted to no longer require
VEX.W to be zero for the instructions to be valid, and to emit proper
suffixes.
Note, however, that this doesn't address the problem of there being no
way to control (at least) {,E}VEX.W for 32- or 16-bit code. Nor does it
address the problem of the many WIG instructions not getting properly
disassembled when VEX.W=1.

Opcodes F6/1 and F7/1 are aliases of F6/0 and F7/0 in all modes. This
complements commit 8b89fe14b5 ("X86: Decode opcode 0x82 as opcode 0x80
in 32-bit mode"), just that here 64-bit mode is also covered.
