2023-01-19howto install_addendAlan Modra1-1/+8
This adds a new flag to the reloc howtos that can be used to incrementally change targets over to simple bfd_install_relocation that just installs the addend without any weird adjustments. I've made a few other changes to bfd_install_relocation, removing dead code and comments that are really only applicable to bfd_perform_relocation. There is also a reloc offset bounds check change. I've moved the check to where data is accessed, as it seems reasonable to me to not perform the check unless it is needed. There is precedence for this; Relocations against absolute symbols already avoided the check. I also tried always performing the reloc offset check, and ran into testsuite failures due to _NONE and _ALIGN relocs at the end of sections. These likely would be fixed if all such reloc howtos had size set to zero, but I would rather not edit lots of files when it involves checking that target code does not use the size. * reloc.c (struct reloc_howto_struct): Add install_addend. (HOWTO_INSTALL_ADDEND): Define. (HOWTO): Init new field with HOWTO_INSTALL_ADDEND. (bfd_install_relocation): Remove comments copied from bfd_perform_relocation that aren't applicable here. Remove code dealing with output_offset and output_section. Just set relocation to addend if install_addend. Move reloc offset bounds check to just before section data is accessed, avoiding the check when data is not accessed. * bfd-in2.h: Regenerate.
2023-01-12Use __func__ rather than __FUNCTION__Alan Modra1-2/+2
We already use C99's __func__ in places, use it more generally. This patch doesn't change uses in the testsuite. I've also left one in gold.h that is protected by GCC_VERSION < 4003.

2023-01-10Re: Move bfd_init to bfd.cAlan Modra1-5/+5
Commit b1c95bc4dd73 resulted in ...bfd.texi:246: @include: could not find init.texi which went unnoticed due to not building in a clean directory. This fixes the problem by moving bfd_init earlier, giving it a doc node, and stitching the nodes back together. * bfd.c (bfd_init): Move earlier. Give it a doc inode. Adjust other inodes to suit. * doc/bfd.texi: Don't include init.texi. Adjust nodes to suit.
2023-01-10Move bfd_init to bfd.cAlan Modra1-11/+9
init.c contains just one function that doesn't do much. Move it to bfd.c and give it something to do, initialising static state. So far the only initialisation is for bfd.c static variables. The idea behind reinitialising state is to see whether some set of flaky oss-fuzz crashes go away. oss-fuzz stresses binutils in ways that can't occur in reality, feeding multiple testcases into the internals of binutils. So one testcase may affect the result of the next testcase. * init.c: Delete file. Move bfd_init to.. * bfd.c (bfd_init): ..here. Init static variables. * Makefile.am (BFD32_LIBS): Remove init.lo.

2023-01-01Update year range in copyright notice of binutils filesAlan Modra1-1/+1

2022-12-17bfd_get_relocated_section_contents allow NULL data bufferAlan Modra1-0/+8
This patch removes the bfd_malloc in default_indirect_link_order and bfd_simple_get_relocated_section_contents, pushing the allocation down to bfd_get_relocated_section_contents. The idea is to make use of the allocation done with sanity checking in bfd_get_full_section_contents, which is called by bfd_generic_get_relocated_section_contents. Doing this exposed a bug in bfd_get_full_section_contents. With relaxation it is possible that an input section rawsize is different to the section size. In that case we want to use the larger of rawsize (the on-disk size for input sections) and size. * reloc.c (bfd_generic_get_relocated_section_contents), * reloc16.c (bfd_coff_reloc16_get_relocated_section_contents), * coff-alpha.c (alpha_ecoff_get_relocated_section_contents), * coff-sh.c (sh_coff_get_relocated_section_contents), * elf-m10200.c (mn10200_elf_get_relocated_section_contents), * elf-m10300.c (mn10300_elf_get_relocated_section_contents), * elf32-avr.c (elf32_avr_get_relocated_section_contents), * elf32-cr16.c (elf32_cr16_get_relocated_section_contents), * elf32-crx.c (elf32_crx_get_relocated_section_contents), * elf32-h8300.c (elf32_h8_get_relocated_section_contents), * elf32-nds32.c (nds32_elf_get_relocated_section_contents), * elf32-sh.c (sh_elf_get_relocated_section_contents), * elfxx-mips.c (_bfd_elf_mips_get_relocated_section_contents): Handle NULL data buffer. * bfd.c (bfd_get_section_alloc_size): New function. * bfd-in2.h: Regenerate. * compress.c (bfd_get_full_section_contents): Correct section malloc size. * linker.c (default_indirect_link_order): Don't malloc memory here before calling bfd_get_relocated_section_contents. * simple.c (bfd_simple_get_relocated_section_contents): Likewise.
2022-12-17Re: The problem with warning in elf_object_pAlan Modra1-0/+7
Commit 5aa0f10c424e added a per_xvec_warn array to provide support for warnings from elf_object_p (and a later patch for warnings from pe_bfd_object_p) to be cached and then only printed if the target matches. It was quite limited in the style of message supported, only one message could be printed, and didn't really meet the stated aim of only warning when a target matches: There are many other errors and warnings that can be emitted by functions called from elf_object_p. So this patch extends the error handler functions to support printing to a string buffer, extends per_xvec_warn to support multiple errors/ warnings, and hooks this all into bfd_check_format_matches. If bfd_check_format_matches succeeds then any errors/warnings are printed for the matching target. If bfd_check_format_matches fails either due to no match or to multiple matches and only one target vector produced errors, then those errors are printed. * bfd.c (MAX_ARGS): Define, use throughout.

2022-12-06Get rid of SEC_ELF_RENAMEAlan Modra1-6/+3
SEC_ELF_RENAME is a flag used to effect section name changes when compressing/decompressing zlib-gnu debug sections. This can be accomplished more directly in one of the objcopy specific bfd functions. Renaming for ld input is simplified too.

2022-12-06Compression header enumAlan Modra1-19/+20
Define an enum instead of using ELFCOMPRESS_ZLIB and ELFCOMPRESS_ZSTD in bfd and binutils, and move some functions from bfd.c to compress.c. When looking at the COFF/PE debug compression support, I wondered about extending it to support zstd. I likely won't do that, but the compression header ch_type field isn't just ELF specific if these headers are to be used in COFF/PE too. bfd/ * bfd.c (bfd_update_compression_header), (bfd_check_compression_header, bfd_get_compression_header_size), (bfd_convert_section_size, bfd_convert_section_contents): Move to.. * compress.c: ..here.

2022-11-15bfd: linker: merge .sframe sectionsIndu Bhagat1-0/+1
The linker merges all the input .sframe sections. When merging, the linker verifies that all the input .sframe sections have the same abi/arch. The linker uses libsframe library to perform key actions on the .sframe sections - decode, read, and create output data. This implies buildsystem changes to make and install libsframe before libbfd. The linker places the output .sframe section in a new segment of its own: PT_GNU_SFRAME. A new segment is not added, however, if the generated .sframe section is empty. When a section is discarded from the final link, the corresponding entries in the .sframe section for those functions are also deleted. The linker sorts the SFrame FDEs on start address by default and sets the SFRAME_F_FDE_SORTED flag in the .sframe section. This patch also adds support for generation of SFrame unwind information for the .plt* sections on x86_64. SFrame unwind info is generated for IBT enabled PLT, lazy/non-lazy PLT. The existing linker option --no-ld-generated-unwind-info has been adapted to include the control of whether .sframe unwind information will be generated for the linker generated sections like PLT. Changes to the linker script have been made as necessary.

2022-10-16zlib-gabi to zstd woesAlan Modra1-3/+0
So we had a zlib-gabi .debug_info section that increased in size with zstd, so much so that it was better to leave the section uncompressed. Things went horribly wrong when the section was read again later. The section was read again off disk using the uncompressed size. So you get the zlib section again with some garbage at the end. Fix that particular problem by setting the section flag SEC_IN_MEMORY. Any future read will get sec->contents. Also, if the section is to be left uncompressed, the input SHF_COMPRESSED flag needs to be reset otherwise objcopy will copy it to output. Finally, bfd_convert_section_contents needed a small update to handle zstd compressed sections, and I've deleted bfd_cache_section_contents. * bfd.c (bfd_convert_section_contents): Handle zstd. * compress.c (bfd_compress_section_contents): When section contents are uncompressed set SEC_IN_MEMORY flag, compress_status to COMRESS_SECTION_NONE, and clear SHF_COMPRESSED.

2022-08-01Get rid of fprintf_vma and sprintf_vmaAlan Modra1-7/+0
These two macros print either a 16 digit hex number or an 8 digit hex number. Unfortunately they depend on both target and host, which means that the output for 32-bit targets may be either 8 or 16 hex digits. Replace them in most cases with code that prints a bfd_vma using PRIx64. In some cases, deliberately lose the leading zeros. This change some output, notably in base/offset fields of m68k disassembly which I think looks better that way, and in error messages.

2022-08-01PR29348, BFD_VMA_FMT wrongAlan Modra1-22/+12
There is a problem with my commit 0e3c1eebb2, which replaced bfd_uint64_t with uint64_t: Some hosts typedef int64_t to long long even when long is the same size as long long. That confuses the code choosing one of "l", "ll", or "I64" for BFD_VMA_FMT, and results in warnings. Write a direct configure test for the printf int64_t style instead. This removes the last use of BFD_HOST_64BIT_LONG, so delete that. Note that the changes to configure.com are pure guesswork. PR 29348 * bfd-in.h (BFD_HOST_64BIT_LONG): Don't define.

Commit 04f096fb9e25 ("Move the xc16x target to the obsolete list") moved the architecture from the "obsolete but still available" to the "obsolete / support removed" list in config.bfd, making the architecture impossible to enable (except maybe via "enable everything" options").

2022-06-14BFD_RELOC_MIPS_16Alan Modra1-1/+1
MIPS should not be using BFD_RELOC_16 for its R_MIPS_16 relocation, since R_MIPS_16 specifies a 16-bit field in a 32-bit word. BFD_RELOC_16, emitted by generic code to handle fixups on 16-bit data directives, expects fixups to operate on the whole of a 16-bit word. This patch corrects the problem by using BFD_RELOC_MIPS_16, a new bfd reloc that is used to generate R_MIPS_16. BFD_RELOC_16 is handled in md_apply_fix for cases where the fixup can be applied at assembly time. Like BFD_RELOC_8, BFD_RELOC_16 now has no corresponding object file relocation, and thus .half, .hword, .short and .dc.w must be resolved at assembly time. BFD_RELOC_MIPS_REL16 is removed by this patch since it isn't used.

2022-06-08Don't encode reloc.sizeAlan Modra1-6/+8

2022-05-27Replace bfd_hostptr_t with uintptr_tAlan Modra1-3/+0
bfd_hostptr_t is defined as a type large enough to hold either a long or a pointer. It mostly appears in the coff backend code in casts. include/coff/internal.h struct internal_syment and union internal_auxent have the only uses in data structures, where comparison with include/coff/external.h and other code reveals that the type only needs to be large enough for a 32-bit integer or a pointer. That should mean replacing with uintptr_t is OK.

2022-03-16bfd: add AMDGCN architectureSimon Marchi1-0/+13
Add support for the AMDGCN architecture to BFD. This is the bare minimum to get $ ./configure --target=amdgcn-hsa-amdhsa --disable-gas $ make all-binutils working later in this series. The specific AMDGCN models added here are a bit arbitrary, based on what we intend to initially support in GDB. This list will need to be updated in the future anyway. The complete up-to-date list of existing AMDGPU models can be found here: https://llvm.org/docs/AMDGPUUsage.html#processors The ELF format for this architecture is documented here: https://llvm.org/docs/AMDGPUUsage.html#elf-code-object The flags for the "HSA" OS ABI are properly versioned and documented on that page. But the NONE, PAL and MESA3D OS ABIs are not well documented nor versioned. Taking a peek at the LLVM source code, we see that they encode their flags the same way as HSA v3. For example, for PAL: https://github.com/llvm/llvm-project/blob/c8b614cd74a92d85936aed5ac7c642af75ffdc29/llvm/lib/Target/AMDGPU/MCTargetDesc/AMDGPUTargetStreamer.cpp#L601 So at least, we know that all AMDGPU objects (of which AMDGCN objects are a subset of) at the time of writing encode the specific GPU model in the EF_AMDGPU_MACH field of e_flags. bfd/ChangeLog: * Makefile.am (ALL_MACHINES, ALL_MACHINES_CFILES): Add cpu-amdgcn.c.

Don't return bed->relropagesize. * elf-bfd.h (struct elf_backend_data): Remove relropagesize. * elfxx-target.h (ELF_RELROPAGESIZE): Remove. * elf32-ppc.c (ELF_RELROPAGESIZE): Don't define. * elf64-ppc.c: Likewise. * bfd-in2.h: Regenerate. ld/ * ldemul.c (after_parse_default): Adjust bfd_emul_get_commonpagesize call.
2022-01-02Update year range in copyright notice of binutils filesAlan Modra1-1/+1
The result of running etc/update-copyright.py --this-year, fixing all the files whose mode is changed by the script, plus a build with --enable-maintainer-mode --enable-cgen-maint=yes, then checking out */po/*.pot which we don't update frequently. The copy of cgen was with commit d1dd5fcc38ead reverted as that commit breaks building of bfp opcodes files.
2021-11-15PowerPC64 @notoc in non-power10 codeAlan Modra1-0/+1
R_PPC64_REL24_P9NOTOC is a variant of R_PPC64_REL24_NOTOC for use on @notoc cals from non-power10 code in the rare case that using such a construct is useful. R_PPC64_REL24_P9NOTOC will be emitted by gas rather than R_PPC64_REL24_NOTOC when @notoc is used in a branch instruction if power10 instructions are not enabled at that point. The new relocation tells the linker to not use power10 instructions on any stub emitted for that branch, unless overridden by --power10-stubs=yes. The current linker heuristic of only generating power10 instructions for stubs if power10-only relocations are detected, continues to be used. include/ * elf/ppc64.h (R_PPC64_REL24_P9NOTOC): Define. bfd/ * reloc.c (BFD_RELOC_PPC64_REL24_P9NOTOC): Define. * elf64-ppc.c (ppc64_elf_howto_raw): Add entry for new reloc.
