We check register-only source operand to decide if two source operands of
VEX encoded instructions should be swapped. But source operands in AMX
instructions with two source operands swapped are all register-only
operand. Add SwapSources to indicate two source operands should be
swapped.

This patch fixes a segfault which occurs when the AArch64 backend parses
a symbol operand that begins with a register name and ends with a
unicode byte (byte value > 127).
For example, the following input causes the crash:
x0é: udf x0é

The xc16x md_apply_fix code is just so broken that in my opinion the
target should never have been accepted, and from a quick look at
commit logs for the target it appears that no one has ever contributed
fixes for anything. This target has just been a 14 year burden on
global binutils and cgen maintainers. That's not how free software is
supposed to work.

The unprivileged CSR should be controlled by other specific specs rather
than the privileged spec. For example, the debug CSR should be controlled
by the debug spec, and the float CSR should be controlled by the float
spec. User may use assembler options to choose what the debug and other
specs they want, or may encode the versions of specs into the architecture
string directly. Since we haven't decided which one is better, we set the
defined and aborted versions of unprivileged CSR to PRIV_SPEC_CLASS_NONE
in the include/opcode/riscv-opc.h, to tell assembler don't check priv spec
versions for them. However, these PRIV_SPEC_CLASS_NONE will be changed
to FLOAT_SPEC_CLASS_* and DEBUG_SPEC_CLASS_* in the future.

Finally; sorry for the delay. There were a few false starts, where I
misinterpreted the error-messages and the comment that Alan added:
it's not the fix size that's too large (and the frag too small), it's
stating the wrong size of what will be "fixed up" - that of the actual
target value, not the size of the field that needs to be adjusted.
Comments added for clarity.

Multiple -M options can be specified in any order. Therefore stright
assignment to fields affected needs to be avoided, such that earlier
options' effects won't be discarded. This was in particular a problem
for -Msuffix followed by certain of the other sub-options.
While updating documentation, take the liberty and also drop the
redundant mentioning of being able to comma-separate multiple options.

This patch adds GNU attribute support to m68k and utilises it to tag the
floating-point calling convention used (hard-float or soft-float). It enables

similar work done for PowerPC.

With abuses of ImmExt gone, all templates using it have operands. Move
its main invocation into process_operands(), matching its secondary one
for the SSE2AVX case.
|
|
Use of an explicit data size or REX.W prefix is sufficient indication of
the intended operation when operand size can't be derived from suffix or
register operands. Avoid the ambiguity warning and make in particular
immediate handling (sizing) cope with explicitly specified prefixes.
Extending/reusing the noreg16 test made me notice a few cases of
unintentional 32-bit addressing, which gets corrected at the same time.
|
|
SYSRET can't use the same macro as IRET, since there's no 16-bit operand
size form of it. Re-use LQ for it instead.
Doing so made obvious that outside of 64-bit mode {,V}CVTSI2S{S,D} and
PTWRITE should have an 'l' suffix printed only in suffix-always mode.
|
|
Just like for the data size prefix (see commit 7a8655d2bbdc ["x86: don't
abort() upon DATA16 prefix on (E)VEX encoded insn"]), any form of REX
prefix is invalid with VEX/XOP/EVEX.
|
|
Legacy encoded insns do so, and their automatic conversion to AVX ones
ought to produce functionally identical code. Therefore explicit REX
prefixes cannot simply be ignored. This is in particular relevant
because at least PCMPESTR{I,M}'s 64-bit forms couldn't be expressed in
older gas by other than using a REX64 prefix.
|
|
The data size prefix alters the meaning of legacy encoded SIMD insns,
and hence shouldn't be accepted there. Use of it also leads to
inconsistencies in SSE2AVX mode. Don't match insns with data size prefix
against SSE2AVX templates.
|
|
Unlike in build_vex_prefix() this is not needed here.

We should generate the ELF priv attributes only if,
1. The priv attributes are already set in the assembly file.
2. The CSR are explicited used.
3. The privileged instruction are explicited used.
* There are four privileged instruction defined in the v1.11 priv spec:
`mret`, `sret`, `wfi` and `sfence.vma`.
* `sfence.vm` is dropped in the v1.10 priv spec.
* `uret` is actually a N-ext instruction. So it is better to regard it as
an user instruction rather than the priv instruction.
* `hret` is used to return from traps in H-mode. H-mode is removed since
the v1.10 priv spec, but probably be added in the new hypervisor spec.
Therefore, `hret` should be controlled by the hypervisor spec rather than
priv spec in the future.
* `dret` is a debug instruction. We should record the debug spec versions
once it is explicited used in the future.

We do know some conflicts among different privileged specs. For linker,
the safest approach is that don't allow the object linked with others which
may cause conflicts. But this may cause inconvenience since not all objects
with conflicting priv specs are linked will cause problems. But it is hard
to know the detailed conflict cases for linker, so we probably need a option
to tell linker that we do know there are no conflicts, or we are willing to
take risks to link the objects with conflicted priv specs. But the option
is still under discussion.
Therefore, we can report warnings rather than errors when linking the objects
with conflicted priv specs. This not only makes the linker more flexible,
but also warns people that the conflicts may happen. We also need to update
the output priv spec version once the input priv spec is newer.

There is a conflict between v1.9 and v1.9.1 - CSR MISA address. MISA is
0xf10 in v1.9, but change to 0x301 in v1.9.1. The change made MISA writable,
but may also cause risk of compatibility. Binutils already support the
-mpriv-spec options and ELF priv attributes, which can used to choose what
privileged spec you want, and then give a correponding CSR name and address
to use. But Gdb and other tools don't have the simialr mechanism for now.
However, there are two things can be confirmed,
1. If we don't have a way to control the priv specs, then the changes, like
MISA, will cause risk and hard to maintain.
2. We get the guarantee that the CSR address won't be reused in the future
specs, even if it is dropped.
I'm not sure if Gdb needs to care about the priv spec versions, it is still
discussing. But drop the priv spec v1.9, and make sure that we won't reuse
the CSR address is a useful solution for now. Also, we might drop the v1.9.1
in a year or two. After that, specs above v1.10 should be compatible anyway.

Commit da4977e00b73 added the 32-bit test files, but failed to add the
64-bit ones.
|
|
All of data size, rep, lock, and rex prefixes are invalid with VEX- and
alike encoded insns. Make sure they get printed explicitly in all cases,
to signal the anomaly. With this, do away with "rex_ignored" - if there
is a rex prefix, we want to print it anyway for VEX etc (and there's
nothing "ignored" about it in the first place - such an instruction will
raise #UD).
|
|
Various AVX insns utilizing the X macro fail to reject F3/F2 embedded
prefix encodings. As the PREFIX_OPCODE attribute wasn't used by any
non-legacy-encoded insns so far, re-use it to achieve the intended
effect.
|
|
An unwanted side effect of 5990e377e5a3 ("x86-64: Intel64 adjustments
for insns dealing with far pointers") was that with -mintel64 LCALL and
LJMP would now default to 64-bit operand size. Since 64-bit far branches
aren't portable, the default operand size should still be 32-bit.
However, since the 64-bit variant is permitted, an ambiguous operand
warning should be issued.
As to the actual code change, please note that the conditional
surrounding the switch() that gets adjusted covers several cases which
are of no interest to or benign in 64-bit mode, hence the new
conditional added can be quite a bit less involved.
|
|
{vex}, {vex3}, and {evex} are mandatory prefixes, and hence should not
be randomly ignored. Fix this for insns without operands as well as for
insns referencing the high 16 [XYZ]MM registers. To achieve the former,
re-purpose VEX_check_operands(), renaming it to VEX_check_encoding() and
moving its only operand check to check_VecOperands().
This involves fixing a testcase relying on {vex2} to get ignored.

Adjustment of this function was missed when support for the respective
registers was added.
|
|
With the introduction of what right now is the very first conditional
in the function's loop (commit dc821c5f9ae5 ["x86: replace Reg8, Reg16,
Reg32, and Reg64"]), the last if() in the same loop has become
pointless - retain just its body.
|
|
First of all, these registers have never been available on any 64-bit
CPU, and hence should not be recognized in 64-bit mode. But even before
that they had already disappeared - also don't recognize them when 586
or 686 architectures were explicitly set.
|
|
While putting together the previous patch I noticed that this test,
forever since its introduction, was dead. Update it so it will pass,
and enable it.
|
|
In 0e0eea782025 ("x86: x87-related adjustments") I screwed up CFI
directives with FPU support disabled, by moving the conditional there
across a check of "allow_pseudo_reg". Add the missing check.

Register aliases (created e.g. via .set) check their target register at
the time of creation of the alias. While this makes sense, it's not
enough: The underlying register must also be "visible" at the time of
use. Wrong use of such aliases would lead to internal errors in e.g.
add_prefix() or build_modrm_byte().
Split the checking part of parse_real_register() into a new helper
function and use it also from the latter part of parse_register() (at
the same time replacing a minor open coded part of it).
Since parse_register() returning NULL already has a meaning, a fake new
"bad register" indicator gets added, which all callers need to check
for.
