2024-05-24gas: extend \+ support to .irp / .irpcJan Beulich1-3/+4
PR gas/31752 These are effectively macro-like, without any separate macro definition. They already support \@, so they would better also support \+. This allows, where desired, to get away without maintaining an explicit count variable in source code. With this the recently introduced testcase doesn't need any xfails anymore.
2024-05-13Add new assembler macro pseudo-variable \+ which counts the number of times ↵Nick Clifton1-0/+4
a macro has been invoked.

2024-03-28gas: sanitize FB- and dollar-label usesJan Beulich1-0/+4
I don't view it as sensible to be more lax when it comes to references to (uses of) such labels compared to their definition: The latter has been limited to decimal numerics, while the former permitted any radix. Beyond that leading zeroes on such labels aren't helpful either. Imo labels and their use sites would better match literally, to avoid confusion. As it turns out, one z80 testcase actually had such an odd use of labels where definition and use don't match in spelling. That testcase is being adjusted accordingly. While there also adjust a comment on a local variable in integer_constant().

2024-03-01s390: Warn when register name type does not match operandJens Remus1-0/+6
Print a warning message when the register type of a specified register name does not match with the operand's register type: operand {#}: expected {access|control|floating-point|general|vector} register name [as {base|index} register] 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: Perform strict register name type checks. warn-regtype-mismatch=relaxed: Perform relaxed register name type checks, which allow floating-point register (FPR) names %f0 to %f15 to be specified as argument to vector 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: no-warn-regtype-mismatch: Disable any register name type checks. 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 mnemonics for every possible operand register type combination. Keep track of the currently parsed operand number to provide it as reference in warning messages. To verify that the introduction of this change does not unnecessarily affect the compilation of existing code the GNU Binutils, GNU C Library, and Linux Kernel have been build with the new assembler, verifying that the assembler did not generate any of the new warning messages. gas/ * config/tc-s390.c: Handle new assembler options "[no]warn-regtype-mismatch[=strict|relaxed|no".

2023-11-24RISC-V: disallow x0 with certain macro-insnsJan Beulich1-0/+3
While for some of the macro insns using x0 is kind of okay, as they would merely resolve to a sequence of hint insns (and hence not cause misbehavior at runtime), several of them have the degenerate AUIPC followed by a load, store, or branch using other than the designated symbol as address and hence causing runtime issues. Refuse to assemble those, leveraging that the matching function so far wasn't really used for macro insns: NULL is now allowed, indicating a match (which imo is preferable over converting match_never() to match_always()), while other matching functions now (also) used for macro insns need to avoid calling match_opcode(). Note that for LA the restriction is slightly too strict: In non-PIC mode using x0 would be okay-ish as per above (as it's just LLA there). Yet libopcodes doesn't know what mode gas is presently assembling for, so we want to err on the safe side. Acked-by: Palmer Dabbelt <palmer@rivosinc.com>
2023-11-23RISC-V: Add T-Head VECTOR vendor extension.Jin Ma1-0/+3
T-Head has a range of vendor-specific instructions ([2]). Therefore it makes sense to group them into smaller chunks in form of vendor extensions. This patch adds the "XTheadVector" extension, a collection of T-Head-specific vector instructions. The 'th' prefix and the "XTheadVector" extension are documented in a PR for the RISC-V toolchain conventions ([1]). Here are some things that need to be explained: The "XTheadVector" extension is not a custom-extension, but a non-standard non-conforming extension. The encoding space of the "TheadVector" instructions overlaps with those of the 'V' extension. This encoding space conflict is not on purpose, but the result of issues in the past that have been resolved since. Therefore, the "XTheadVector" extension and the 'V' extension are in conflict.

2023-09-14x86: support AVX10.1 vector size restrictionsJan Beulich1-0/+2
Recognize "/<number>" suffixes on both -march=+avx10.1 and the corresponding .arch directive, setting an upper bound on the vector size that insns may use. Such a restriction can be reset by setting a new base architecture, by using a suffix-less form, by disabling AVX10, or by enabling any other VEX/EVEX-based vector extension. While for most insns we can suppress their use with too wide operands via registers becoming unavailable (or in Intel syntax memory operand size specifiers not being recognized), mask register insns have to have their minimum required vector size specified in a new attribute. (Of course this new attribute could also be used on other insns.) Note that .insn continues to be permitted to emit EVEX{512,256} (and VEX256 ones) encodings regardless of vector size restrictions in place. Of course these can't be expressed using zmm (or ymm) operands then, but need using the EVEX.512.* forms (broadcast forms may be usable right now, but this may go away so shouldn't be relied upon). This is why no assertions should be added to build_{e,}vex_prefix().
