Running the testsuite for an x86_64-w64-mingw32 target using the Ubuntu package gcc-mingw-w64-x86-64 version 13.2.0-6ubuntu1+26.1 results in a number of messages: ERROR: can't decipher gcc version number, fix the framework! Someone in their wisdom decided this compiler should advertise itself with a version of 13-win32, breaking the ld testsuite version checks. (It is also configured using --with-as=/usr/bin/x86_64-w64-mingw32-as --with-ld=/usr/bin/x86_64-w64-mingw32-ld which renders the -B flag inoperative for testing the newly built gas and ld.

This brings us down to just these fails for the set of targets I usually test when making testsuite changes. aarch64-pe +FAIL: ld-pe/symbols-ordinals-hints-imports-ld arm-pe +FAIL: ld-pe/symbols-ordinals-hints-exports-dlltool arm-pe +FAIL: ld-pe/symbols-ordinals-hints-imports-dlltool The aarch64 one is likely due to the target missing support somewhere. It is fairly new, I haven't investigated. The arm-pe fails are due to arm-pe being a target that adds underscores to symbol names (see config.bfd) whereas dlltool thinks it does not (see dlltool.c:asm_prefix). arm-wince-pe on the other hand doesn't add underscores. I would guess the right fix for dlltool is to get this symbol info from bfd using bfd_get_target_info. Note I'm not very happy about the creative use of ld_after_inputfile in symbols-ordinals-hints-imports-ld.d, which is likely to break with some future run_dump_test change.

14 daysld/testsuite: add missing definition to PDB testMark Harmstone3-13/+14
The file pdb-syms1a.s was missing a definition for T_VOID, which was causing some types not to be deduplicated. It also meant that the test couldn't be run against LLVM's lld, which throws an error for this. This particular test only tests the symbols stream, not the types stream, which is why the deduplication doesn't result in a change in the file size.

It's because the indices in .plt and .rela.plt mismatches for STV_DEFAULT STT_IFUNC symbols when another PLT entry exists for a STV_HIDDEN STT_IFUNC symbol, and such a mismatch breaks the logic of loongarch_elf_finish_dynamic_symbol.

If we keep the R_LARCH_32 reloc as-is in ELFCLASS64, it'll be rejected by the Glibc dynamic linker anyway. And it does not make too much sense to modify Glibc to support it. So we can just reject it like x86_64: relocation R_X86_64_32 against `.data' can not be used when making a shared object; recompile with -fPIC or RISC-V: relocation R_RISCV_32 against non-absolute symbol `a local symbol' can not be used in RV64 when making a shared object Signed-off-by: Xi Ruoyao <xry111@xry111.site>
2024-07-04gas: Skip SFrame FDE if CFI specifies non-FP/SP base registerJens Remus1-1/+0
Do not generate SFrame FDE if DWARF CFI directives .cfi_def_cfa or .cfi_def_cfa_register specify a CFA base register number other than the architecture-specific stack-pointer (SP) or frame-pointer (FP) register numbers. This also causes the assembler to print a warning message, so that skipping of the SFrame FDE does not occur silently. Update the generic ld SFrame test case to be architecture independent. Do not use CFI directive .cfi_def_cfa, as the specified CFA base register number is not a valid SP/FP register number on all architectures. An invalid SP/FP register number will now cause the assembler to print a warning message and skip SFrame FDE generation. Remove the offending CFI directive, that cannot be coded architecture- independent, as the test case requires SFrame information to be generated.

2024-07-04readelf/objdump: Dump SFrame CFA fixed FP and RA offsetsJens Remus2-0/+2
The SFrame format allows architectures to specify fixed offsets from the CFA, if any, from which the frame pointer (FP) and/or return address (RA) may be recovered. These offsets are stored in the SFrame header. For instance the SFrame generation in the assembler for x86 AMD64 specifies a fixed offset from the CFA, from which the return address (RA) may be recovered. When dumping the SFrame header, for instance in readelf/objdump with option --sframe, do also dump the specified fixed offsets from the CFA, if any, from which the frame pointer (FP) and return address (RA) may be recovered. Update the common SFrame test case verification patterns to allow for the optional dumping of the CFA fixed FP/RA offsets.

The "DWARF parse during linker error" and "Build warn libbar.so" tests require debug information. configure defaults to "-O2 -g" but if overriding *FLAGS when building tests, this might be lost. Explicitly pass -g given these tests require it.

2024-06-28RISC-V: PR27180, Update relocation for riscv_zero_pcrel_hi_reloc.Nelson Chu2-0/+27
When pcrel access overflow, the riscv_zero_pcrel_hi_reloc may convert pcrel relocation to absolutly access if possible at the relocate stage. We used to encode the target address into r_sym of R_RISCV_HI20 if it is converted from R_RISCV_PCREL_HI20. But that may cause segfault if --emit-relocs is set, since r_sym becomes an address rather than a symbol index. Although the relocate result is correct, it does not meet the definition, so may cause unexpected behaviors. This patch encodes the target address into r_addend, rather than r_sym, if riscv_zero_pcrel_hi_reloc converts the relocation. Besdies, since the corresponding pcrel_lo relocation are also changed to absolutly access, we should also update them to R_RISCV_LO12_I/S. bfd/ PR 27180 * elfnn-riscv.c (riscv_pcrel_hi_reloc): New boolean `absolute', to inform corresponding pcrel_lo that the pcrel_hi relocation was already converted to hi20 relocation. (riscv_record_pcrel_hi_reloc): Likewise, record `absolute'. (riscv_pcrel_lo_reloc): Removed `const' for Elf_Internal_Rela *reloc, since we may need to convert it from pcrel_lo to lo relocation. (riscv_record_pcrel_lo_reloc): Likewise. Convert pcrel_lo to lo relocation if corresponding pcrel_hi was converted to hi relocation. (riscv_zero_pcrel_hi_reloc): Encode target absolute address into r_addend rather than r_sym. Clear the `addr' to avoid duplicate relocate in the perform_relocation. (riscv_elf_relocate_section): Updated. ld/ PR 27180 * testsuite/ld-riscv-elf/pcrel-lo-addend-3a-emit-relocs.d: New testcase. Segfault without applying this patch. * testsuite/ld-riscv-elf/ld-riscv-elf.exp: Updated.

2024-06-24libdep plugin: fix bugs in parser and drop escapingHarmen Stoppels1-94/+80
PR ld/31906 * libdep_plugin.c (str2vec): Fix bug where null byte was not copied on memmove during quote handling and escaping, causing repeat of the last character in the last argument. Fix buffer overflow in **res when arguments were separated by `\t` instead of ` `. Remove handling of the escape character `\`, as it made it impossible to specify paths containing `\` -- the implementation merely dropped `\`, and was affected by the memmove bug, so this should not be breaking; just single and double quotes are sufficient to deal with white space and quote characters, there is no need for escaping. Handle syntax errors on unterminated quotes. Make the parser linear time instead of quadratic.
