For one 0afc614c99 ("x86: Warn .insn instruction with length > 15
bytes") introduced a .insn use involving a slash; such tests need to
have --divide passed to gas.
And then 5bc71c2a6b ("x86-64: Add R_X86_64_CODE_6_GOTTPOFF") broke
BFD_RELOC_X86_64_GOTTPOFF conversion to R_X86_64_CODE_4_GOTTPOFF, by
adding respective code in a section guarded by
generate_relax_relocations (the case of that not being required there
was limited to 32-bit object files). Re-arrange that block of code to
check generate_relax_relocations later.
This relaxation is effective for both macro instructions (call36, tail36)
and explicit relocation instructions (pcaddu18i + jirl).
call36 f -> bl f
R_LARCH_CALL36 -> R_LARCH_B26
tail36 $t0, f -> b f
R_LARCH_CALL36 -> R_LARCH_B26
The following instructions are added in this patch:
- ADDPT (predicated): Add checked pointer vectors (predicated).
- ADDPT (unpredicated): Add checked pointer vectors (unpredicated).
- SUBPT (predicated): Subtract checked pointer vectors (predicated).
- SUBPT (unpredicated): Subtract checked pointer vectors (unpredicated).
- MADPT: Multiply-add checked pointer vectors, writing multiplicand
- MLAPT: Multiply-add checked pointer vectors, writing addend
These instructions are part of Checked Pointer Arithmetic extension
and are enabled when both CPA and SVE are enabled. To achieve this,
both flag "+sve" and "+cpa" should be active.
This patch adds assembler and disassembler support for these instructions
with relevant checks. Tests are included as well.
Regression tested on the aarch64-none-linux-gnu target and no regressions

Except for bfml{a,s} their 1st and 3rd operands need to match - pass
the TIED macro argument accordingly. While doing that also slightly
re-arrange table entries, such that all predicated insns are close
together.
At the same time change the existing test source to actually use non-
matching operands for the respective bfml{a,s} forms.
Their index is in bits 19, 20, and 22. Bit 11 in particular is already
set in the base opcode. Note also how disassembler output didn't match
assembler input in the respective testcase.
Irrespective of the encoding being EVEX, the usable SIMD register range
continues to be limited to %xmm0-%xmm15. Enforce this in gas (but
continue to generate code, as in principle we know how to encode
things) and recognize/flag the case in the disassembler.
Oddly enough wrong forms were actually used in the testsuite (register-
only forms are then really meaningless to test here, and are hence
dropped instead of adjusted).
Convert the POP2 test that needs touching anyway (due to a bad ModR/M
byte having been chosen) to .insn.
Use -march=help for gas to print all supported extensions and versions.
Here is part of the output of `as -march=help`:
All available -march extensions for RISC-V:
e 1.9
i 2.1, 2.0
m 2.0
a 2.1, 2.0
f 2.2, 2.0

q 2.2, 2.0
c 2.0
v 1.0
h 1.0
zicbom 1.0
zicbop 1.0
...
This patch assumes that the supported extensions with the same versions
are listed together. For example:
static struct riscv_supported_ext riscv_supported_std_ext[] =
{
...
{"i", ISA_SPEC_CLASS_20191213, 2, 1, 0 },
{"i", ISA_SPEC_CLASS_20190608, 2, 1, 0 },
{"i", ISA_SPEC_CLASS_2P2, 2, 0, 0 },
...
};
For the "i" extension, 2.1.0 with different spec class are listed together.
This patch records the previous printed extension and version. If the
current extension and version are the same as the previous one, skip
printing.

Introduce a s390-specific assembler option "warn-regtype-mismatch"
with the values "strict", "relaxed", and "no" as well as an option
"no-warn-regtype-mismatch" which control whether the assembler
performs register name type checks and generates above warning messages.
warn-regtype-mismatch=strict:

register (VR) operands and vector register (VR) names %v0 to %v15 to
be specified as argument to floating-point register (FPR) operands.
This is acceptable as the FPRs are embedded into the lower halves of
the VRs. Make "relaxed" the default, as GCC generates assembler code
using FPR and VR interchangeably, which would cause assembler warnings
to be generated with "strict".
warn-regtype-mismatch=no:

Tag .insn pseudo mnemonics as such, to skip register name type checks
on those. They need to be skipped, as there do not exist .insn pseudo

The combination of an architecture size of 32 bits and z/Architecture
mode requires the highgprs flag to be set in the ELF output. It causes
the high-halves of the general purpose registers (GPRs) to be preserved
at run-time, so that the code can use 64-bit GPRs.
The architecture size of 32 bits can either be the default in case of
a default architecture name of "s390" or due to specification of the
option -m31 (to generate the 31-bit file format).
The z/Architecture mode can either be the default or due to
specification of the option -mzarch (to assemble for z/Architecture
mode). It can also be selected using the pseudo commands
".machinemode zarch" and ".machinemode zarch_nohighgprs". The latter
not causing the highgprs flag to be set.
The highgprs flag was only set when the following s390-specific
assembler options were given in the following specific order:
"-m31 -mzarch".
The highgprs flag was erroneously not set when:
- the order of above options was inverse (i.e. "-mzarch -m31"),
- the architecture mode defaulted to z/Architecture mode and
option "-m31" was specified,
- the architecture size defaulted to 32 bits due to a default
architecture name of "s390" and option -mzarch was specified,
- the architecture size defaulted to 32 bits and the architecture
mode defaulted to z/Architecture due to the specified processor
(e.g. "-march=z900" or follow-on processor).
Determine whether to set the highgprs flag in init_default_arch() after
having processed all assembler options in md_parse_option(). This
ensures the flag is set in all of the above cases it was erroneously not
set. Add test cases for highgprs flag, including ones that use
.machinemode to switch the architecture mode.

While most logic in optimize_encoding() is already covering APX by way
of the earlier NDD->REX2 conversion, there's a remaining set of cases
which wants handling separately.
In this case spaces 0f38 and 0f3a may not be put in place. To achieve
the intended effect, operand parsing (but not operand processing) needs
pulling ahead, so we know whether eGRP-s are in use.
Even when an EVEX encoding is available, use of such a prefix ought to
be respected (resulting in an error) rather than ignored. As requested
during review already, introduce a new encoding enumerator to record use
of eGPR-s, and update state transitions accordingly.
The optimize_encoding() change also addresses an internal assembler
error that was previously raised when respective memory operands used
eGPR-s for addressing.
While this results in a change of diagnostic issued for VEX-encoded
insns, the new one is at least no worse than the prior one.

with the same section names. Using a hash table to quickly find a

To reduce the number of times we traverse the section list, the patch

This patch moves the existing sysreg tests for AArch64 into a subdirectory
(sysreg). The number of test files related to system registers grew
relatively big with time and makes the browsing of those files difficult.
Moreover, the difference of naming for the failure, working, and
feature-specific scenarios causes the tests not to appear next to one
another in the exploration tree when it is ordered alphabetically.
TCA instructions start with an X, this introduces ambiguities when it
comes to XOR (Is it the OR on the TCA or the XOR of the core?). For this
reason, we rename OR to IOR and XOR to EOR.
OR and XOR variants are still valid on KV3-1 and KV3-2. However, they

The detection of negative powers of 2 was wrong and could lead to
well-formed bundles ending up taking more syllables than necessary.

This adds teh following files that were missing in the previous
commit ecd16ae4e4
testsuite/gas/bpf/indcall-badoperand.d
testsuite/gas/bpf/indcall-badoperand.l
testsuite/gas/bpf/indcall-badoperand.s
As a result of a switch instead of an if, as would issue non-specific
error messages when it encountered an operand it could not parse in bpf.
This patch fixes that regression and adds a test to prevent it from
reoccurring.
Tested for bpf-unknown-none on x86_64-redhat-linux.
gas/ChangeLog:
* config/tc-bpf.c (parse_expression): Change switch to if so that error
* condition is handled.
* testsuite/gas/bpf/bpf.exp: Invoke new test.
* testsuite/gas/bpf/indcall-badoperand.d: New test.
* testsuite/gas/bpf/indcall-badoperand.l: New test.
* testsuite/gas/bpf/indcall-badoperand.s: New test.
