4 daysx86: restrict gas'es recognition of -s to SolarisJan Beulich1-3/+8
When there for Solaris compatibility only, also recognize it only there. This way the option becomes available for other possible uses. While adjusting md_shortopts[], also re-arrange things such that we have only a single, uniform definition of it.
4 daysx86/Solaris: support Sun form of CMOVccJan Beulich4-0/+80
Sun specifies an alternative form for CMOVcc [1], which for some reason we never cared to support, even if - as per gcc's configure checking for it - it may have been the only permitted form at some point. While documentation doesn't indicate FCMOVcc to have similar alternative forms, gcc assumes so. Hence cover FCMOVcc as well. [1] https://docs.oracle.com/cd/E37838_01/html/E61064/ennbz.html#XALRMeoizm
4 daysx86: purge most *avx512*ig*-intel testsJan Beulich24-6996/+4
Having just one each (AVX512F) ought to be sufficient to cover Intel syntax disassembly. In x86-64.exp also reorder tests some, so that related ones are again next to each other, rather than being interspersed with APX ones.

Assorted targets do not check, as the ELF targets do, that the program name in a core file is NUL terminated. Fix some of them. I haven't attempted to fix all targets because editing host specific code can easily result in build bugs, which aren't discovered until someone build binutils for that host. (Of the files edited here, I can't easily compile hpux-core.c and osf-core.c on a linux system.) PR 32399 * hppabsd-core.c (hppabsd_core_core_file_p): Ensure core_command string is terminated. * hpux-core.c (hpux_core_core_file_p): Likewise. * irix-core.c (irix_core_core_file_p): Likewise. * lynx-core.c (lynx_core_file_p): Likewise. * osf-core.c (osf_core_core_file_p): Likewise. * mach-o.c (bfd_mach_o_core_file_failing_command): Likewise.

In commit 58776901074 ("[gdb/syscalls] Update to linux v6.11") I updated to linux v6.11, but a recent submission for loongarch [1] used a current trunk version, so it makes sense to do this as well elsewhere. Using linux current trunk with update-linux-from-src.sh gets us 4 more syscalls: - setxattrat - getxattrat - listxattrat - removexattrat Tested on x86_64-linux.

6 daysgdb/testsuite: skip gdb.threads/omp-par-scope.exp with clangGuinevere Larsen1-0/+8
Since 2020 it has been reported to clang[1] that the debug information around OpenMP is insufficient. The OpenMP section is not declared within the correct scope, and instead clang marks as if the section was a function in the global scope. This causes several failures in the test gdb.threads/omp-par-scope.exp when using clang to test GDB. Since this isn't a true failure of GDB, and there is little expectation that clang will be able to fix this soon, this commit disables the aforementioned test when clang is being used.

6 days[gdb/symtab] Fix parent map dumpTom de Vries4-12/+36
Before the fix for PR symtab/32225, the parent map dump showed a mapping from section offsets to cooked index entries: ... 0x0000000000000035 0x3ba9560 (0x34: sp1::A) ... but now that's no longer the case: ... 0x00000000406f5405 0x410a04d0 (0x34: sp1::A) ... Fix this by extending the annotation somewhat, such that we get: ... map start: 0x0000000012c52405 0x135fd550 (section: .debug_info, offset: 0x35) -> (0x34: sp1::A) ... Tested on x86_64-linux.

Using: ... $ gdb -q -batch -iex "maint set worker-threads 0" a.out -ex "maint print objfiles" ... we get a cooked index entry with incorrect parent: ...

The problem is that the parent map assumes that all offsets are in the same section. Fix this by using dwarf2_section_info::buffer-relative addresses instead, which get us instead: ...

7 daysnios2: Remove binutils support for Nios II target.Sandra Loosemore337-23162/+12
The Nios II architecture has been EOL'ed by the vendor. This patch removes all binutils, bfd, gas, binutils, and opcodes support for this target with the exception of the readelf utility. (The ELF EM_* number remains valid and the relocation definitions from the Nios II ABI will never change in future, so retaining the readelf support seems consistent with its purpose as a utility that tries to parse the headers in any ELF file provided as an argument regardless of target.)

7 daysPR32387 ppc64 TLS optimization bug with -fno-plt codeAlan Modra1-0/+9
The inline plt code emitted by gcc is incompatible with the linker/ld.so --tls-get-addr-optimize scheme. This is the runtime optimisation where the first call to __tls_get_addr results in __tls_get_addr updating the tls_index pair, then the special linker stub using that to short-circuit second and subsequent calls for a given tls symbol. Enabled by default when the linker sees __tls_get_addr_opt is preseent, and enabled in ld.so when DT_PPC64_OPT has PPC64_OPT_TLS set. Note that this is distinct from link-time tls optimisation. PR 32387 * elf64-ppc.c (ppc64_elf_check_relocs): Disable tls_get_addr_opt on detecting inline plt calls to __tls_get_addr.

I tried to use arm-linux.py to regenerate arm-linux.xml.in, but it didn't work. Fix this by: - adding handling of arm-linux.xml.in in update-linux-from-src.sh, - regenerating arm-linux.xml.in using update-linux-from-src.sh and linux 6.11 sources, - regenerating arm-linux.xml using make, and - removing arm-linux.py.

8 daysConvert typedef hash to new hash tableSimon Marchi3-110/+71
This converts the typedef hash to use the new hash table. This patch found a latent bug in the typedef code. Previously, the hash function looked at the type name, but the hash equality function used types_equal -- but that strips typedefs, meaning that equality of types did not imply equality of hashes.
