2024-07-16[gdb/testsuite] Simplify gdb.base/complex-parts.expTom de Vries1-39/+42
I noticed a lot of escaping in test-case gdb.base/complex-parts.exp. Make the test-case more readable by using: - string_to_regexp, and - {} instead of "". Tested on x86_64-linux and aarch64-linux.

A problem internal to GDB has been detected, further debugging may prove unreliable. ``` The change in step-precsave.exp triggers this bug, since now the recording is loaded in a new gdb session, where record_full_resume_ptid was never set.

2024-07-14hppa: Fix handling of relocations that apply to dataJohn David Anglin1-37/+51
Commit d125f9675372b1ae01ceb1893c06ccb27bc7bf22 introduced a bug in handling relocations for data. The R_PARISC_DIR32 relocation operates on 32-bit data and not instructions. The HOWTO table needs to be used to determine the format of relocations that apply to data. The R_PARISC_SEGBASE relocation is another special case as it only changes segment base. This was noticed in Debian cmor package build. 2024-07-14 John David Anglin <danglin@gcc.gnu.org> bfd/ChangeLog: * elf32-hppa.c (final_link_relocate): Use HOWTO table to determine reload format for relocations that apply to data.

2024-07-12aarch64: Add support for sme2.1 zero instructions.Srinath Parvathaneni10-210/+610
This patch adds support for following sme2.1 zero instructions and the spec is available here [1]. 1. ZERO (single-vector). 2. ZERO (double-vector). 3. ZERO (quad-vector). The VECTOR GROUP symbols VGx2 and VGx4 are optional for the assembler for most of the sme and sve instructions. But for few of the sme2.1 zero instruction variants VECTOR GROUP symbols VGx2 and VGx4 are mandatory. To address this a bit "F_VG_REQ" is introduced in this patch, on setting F_VG_REQ bit in flags of aarch64_opcode forces the assembler to accept instruction operand only having VECTOR GROUP symbols.

2024-07-12x86: drop unnecessary \() from bundle testsJan Beulich3-15/+15
':' isn't permitted in macro parameter names, hence this separator construct isn't necessary at the end of labels. Drop its use in such cases, for being potentially confusing (and hampering readability, even if only a little).
2024-07-12x86/APX: remove two inconsistenciesJan Beulich7-81/+283
As indicated in earlier discussion, permitting GOTTPOFF uniformly for all legacy non-SIMD insns while at the same time restricting to just certain ADD forms when EVEX-encoded is inconsistent. Make promoted insns "equal" to their legacy original ones. Doing that adjustment prevents another inconsistency, too: In data16 neg (%rax) data16 neg (%r16) data16 {nf} neg (%rax) it is not logical why the last one shouldn't be permitted. Bypassing that check requires other adjustments, though, to actually properly consume (and then squash) the data size prefix. While there also add the missing CMP and TEST cases to the test case being modified.

2024-07-11gas: multi-byte warning adjustmentsJan Beulich8-11/+41
First input_scrub_next_buffer()'s invocation was wrong, leading to input only being checked from the last newline till the end of the current buffer. Correcting the invocation, however, leads to duplicate checking unless -f (or the #NO_APP equivalent thereof) is in effect. Move the invocation to input_file_give_next_buffer(), to restrict it accordingly. Then, when macros contain multi-byte characters, warning about them again in every expansion isn't useful. Suppress such warnings from sb_scrub_and_add_sb().
2024-07-11gas: there's no scrubber state 12Jan Beulich1-4/+1
Apparently (beyond what's [easily] visible in git history) when this was added there was confusion about scrubber states vs lex[] contents. For the purposes here LEX_IS_DOUBLEDASH_1ST (which happens to also resolve to 12) alone is sufficient. "state" is never set to 12, and it being 12 also isn't handled anywhere.
