Dot products deviate from the normal disassembly rules for lane indexed
instruction. Their canonical representation is in the form of:
v0.2s, v0.8b, v0.4b[0] instead of v0.2s, v0.8b, v0.b[0] to try to denote
that these instructions select 4x 1 byte elements instead of a single 1 byte
element.
Previously we were disassembling them following the normal rules, this patch
corrects the disassembly.

Previously parse_vector_type_for_operand was changed to allow the use of 4b
register size for indexed lane instructions. However this had the unintended
side effect of also allowing 4b for normal vector registers.
Because this support was only partial the rest of the tool silently treated
4b as 8b and continued. This patch adds full support for 4b so it can be
properly distinguished from 8b and the correct errors are generated.
With this patch you still can't encode any instruction which actually requires
v<num>.4b but such instructions don't exist so to prevent needing a workaround
in get_vreg_qualifier_from_value this was just omitted.

Just like for instructions in GPRs, there's no need to have separate
templates for otherwise identical insns acting on XMM or YMM registers
(or memory of the same size).
|
|
... qualified by their respective sizes, allowing to drop FirstXmm0 at
the same time.
|
|
Express them as Reg|Tbyte and Acc|Tbyte respectively.
|
|
Use a combination of a single new Reg bit and Byte, Word, Dword, or
Qword instead.
Besides shrinking the number of operand type bits this has the benefit
of making register handling more similar to accumulator handling (a
generic flag is being accompanied by a "size qualifier"). It requires,
however, to split a few insn templates, as it is no longer correct to
have combinations like Reg32|Reg64|Byte. This slight growth in size will
hopefully be outweighed by this change paving the road for folding a
presumably much larger number of templates later on.

Again these look to be typos: No template currently allows for any two
(or all three) of RegXMM, RegYMM, and RegZMM in a single operand. Quite
clearly ! are missing, after the addition of which the checks for the
first and (if present) second operands also fully match up.
|
|
I'm rather certain the missing ! was just a typo, the more with the
similar check in mind that's in the same function a few hundred lines
down (in the body of "if (vex_reg != (unsigned int) ~0)"). Of course
this can't be demonstrated by a test case - internal data structure
consistency is being checked here, and neither form of the check
triggers with any current template.
It is also not really clear to me why operand_type_equal() is being used
in the {X,Y,Z}MM register check here, rather than just testing the
respective bits: Just like Reg32|Reg64 is legal in an operand template,
I don't see why e.g. RegXMM|RegYMM wouldn't be. For example it ought to
be possible to combine
vaddpd, 3, 0x6658, None, 1, CpuAVX, Modrm|Vex|VexOpcode=0|VexVVVV=1|VexW=1|IgnoreSize|No_bSuf|No_wSuf|No_lSuf|No_sSuf|No_qSuf|No_ldSuf, { Xmmword|Unspecified|BaseIndex|Disp8|Disp16|Disp32|Disp32S|RegXMM, RegXMM, RegXMM }
vaddpd, 3, 0x6658, None, 1, CpuAVX, Modrm|Vex=2|VexOpcode=0|VexVVVV=1|VexW=1|IgnoreSize|No_bSuf|No_wSuf|No_lSuf|No_sSuf|No_qSuf|No_ldSuf, { Ymmword|Unspecified|BaseIndex|Disp8|Disp16|Disp32|Disp32S|RegYMM, RegYMM, RegYMM }
into a single template (with setting of VEX.L suitably handled elsewhere
if that's not already happening anyway).
Additionally I don't understand why this uses abort() instead of
gas_assert().
Both of these latter considerations then also apply to the
aforementioned other check in the same function.

There is a recurring pattern in assembly files generated by a compiler
where a lot of jumps in a function are going to the same place. When
these jumps are relaxed with trampolines the assembler generates a
separate jump thread from each source.

jump being relaxed goes to a location from that index, in which case
replace its target with a location of existing trampoline jump that

Replace linked list of trampoline frags with an ordered array, so that
instead of indexing fixups trampolines could be indexed. Keep each array
in the trampoline_seg structure, so there's no need to rebuild it for
every new processed segment. Don't run relaxation for each trampoline
frag, instead run it for each fixup in the current segment that needs
relaxation at the beginning of each relaxation pass. This way the
complexity of this process drops from about O(n^2 * m) to about
O(log n * m), where n is the number of trampoline frags and m is the
number of fixups that need relaxation in the segment.

* config/tc-xtensa.h (xtensa_frag_type): Remove next_trampoline.
* testsuite/gas/xtensa/trampoline.d: Adjust absolute addresses
as the placement of trampolines has slightly changed.

stays in sync with instruction stream.

The split between fragS and trampoline_frag doesn't save much space, but
makes trampolines management much more awkward. Merge trampoline_frag
data into the xtensa_frag_type, which is a part of fragS. No functional
changes.

xtensa_create_trampoline_frag has opencoded fragment equivalent to
find_trampoline_seg. Drop the fragment and use find_trampoline_seg
instead. No functional changes.

init_trampoline_frag, add_jump_to_trampoline and xg_relax_trampoline add
a jump to the end of a trampoline frag. Extract it into a separate
funciton and use it in all these places. No functional changes.

For one the register type used for masking should be validated. And then
we shouldn't accept input producing encodings which will #UD when
executed, as is the case when EVEX.Z is set while EVEX.AAA is zero.
