2022-12-26bfd/dwarf2.c: allow use of DWARF5 directory entry 0Alan Modra1-13/+10
I think the test for table->files[file].dir being non-zero is wrong for DWARF5 where index zero is allowed and is the current directory of the compilation. Most times this will be covered by the use of table->comp_dir (from DW_AT_comp_dir) in concat_filename but the point of putting the current dir in .debug_line was so the section could stand alone without .debug_info. Also, there is no need to check for table->dirs non-NULL, the table->num_dirs test is sufficient. * dwarf2.c (concat_filename): Correct and simplify tests of directory index.

2022-12-22PR29925, Memory leak in find_abstract_instanceAlan Modra1-12/+19
The testcase in the PR had a variable with both DW_AT_decl_file and DW_AT_specification, where the DW_AT_specification also specified DW_AT_decl_file. This leads to a memory leak as the file name is malloced and duplicates are not expected. I've also changed find_abstract_instance to not use a temp for "name", because that can result in a change in behaviour from the usual last of duplicate attributes wins.

2022-12-21enable-non-contiguous-regions warningsAlan Modra11-52/+19
The warning about discarded sections in elf_link_input_bfd doesn't belong there since the code is dealing with symbols. Multiple symbols in a discarded section will result in multiple identical warnings about the section. Move the warning to a new function in ldlang.c. The patch also tidies the warning quoting of section and file names, consistently using `%pA' and `%pB'. I'm no stickler for one style of section and file name quoting, but they ought to be consistent within a warning, eg. see the first one fixed in ldlang.c, and when a warning is emitted for multiple targets they all ought to use exactly the same format string to reduce translation work. elf64-ppc.c loses the build_one_stub errors since we won't get there before hitting the fatal errors in size_one_stub. bfd/ * elflink.c (elf_link_input_bfd): Don't warn here about discarded sections. * elf32-arm.c (arm_build_one_stub): Use consistent style in --enable-non-contiguous-regions error. * elf32-csky.c (csky_build_one_stub): Likewise. * elf32-hppa.c (hppa_build_one_stub): Likewise. * elf32-m68hc11.c (m68hc11_elf_build_one_stub): Likewise. * elf32-m68hc12.c (m68hc12_elf_build_one_stub): Likewise. * elf32-metag.c (metag_build_one_stub): Likewise. * elf32-nios2.c (nios2_build_one_stub): Likewise. * elfnn-aarch64.c (aarch64_build_one_stub): Likewise. * xcofflink.c (xcoff_build_one_stub): Likewise. * elf64-ppc.c (ppc_size_one_stub): Likewise.

2022-12-17bfd_get_relocated_section_contents allow NULL data bufferAlan Modra18-51/+143
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 Modra9-75/+279
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.

2022-12-15libsframe asan: avoid generating misaligned loadsIndu Bhagat1-12/+12
There are two places where unaligned loads were seen on aarch64: - #1. access to the SFrame FRE stack offsets in the in-memory representation/abstraction provided by libsframe. - #2. access to the SFrame FRE start address in the on-disk representation of the frame row entry. For #1, we can fix this by reordering the struct members of sframe_frame_row_entry in libsframe/sframe-api.h. For #2, we need to default to using memcpy instead, and copy out the bytes to a location for output. SFrame format is an unaligned on-disk format. As such, there are other blobs of memory in the on-disk SFrame FRE that are on not on their natural boundaries. But that does not pose further problems yet, because the users are provided access to the on-disk SFrame FRE data via libsframe's sframe_frame_row_entry, the latter has its' struct members aligned on their respective natural boundaries (and initialized using memcpy).
