This adds a mingw target for aarch64, including windres and dlltool. Note that the old value of jmp_aarch64_bytes was wrong, and this does the same thing as MSVC does.

2023-01-06Make coff backend data read-onlyAlan Modra1-19/+16
The bfd_coff_backend_data struct should be read-only, the only thing preventing this is that objcopy writes to one of the fields, _bfd_coff_long_section_names. This patch creates a copy of the field in bfd coff_obj_tdata, which makes more sense anyway. When enabling long section names the intent is to do so for a particular bfd, not for all bfds that might happen to be using the target xvec. bfd/ * coffcode.h: Update coff long section name comment. (bfd_coff_set_long_section_names_allowed): Use macro accessor to set flag. (bfd_coff_set_long_section_names_disallowed): Tidy. (coff_backend_info): Return a const pointer.

2023-01-04objcopy fuzzed pe out of memoryAlan Modra1-0/+4
This occurs when attempting to read back a section from the output file in _bfd_XX_bfd_copy_private_bfd_data_common. The copy of the section failed size sanity checking, thus it won't be written. * objcopy.c (copy_object): Return false if copy_section or copy_relocations_in_section fails.
2023-01-04fuzzed file timeoutAlan Modra1-1/+2
objcopy of archive, element containing an object with a fuzzed section size far exceeding the element size. copy_section detects this, but the temp file is laid out for the large section. It can take a long time to write terabytes of sparse file, a waste of time when it will be deleted. * objcopy.c (copy_archive): Don't write element contents after bad status result from copy_object.

2022-12-30PR29948, heap-buffer-overflow in display_debug_lines_decodedAlan Modra1-52/+64
This fixes a couple of places in display_debug_lines_decoded that were off by one in checking DWARF5 .debug_line directory indices. It also displays the DWARF5 entry 0 for the program current directory rather than "." as is done for pre-DWARF5. I decided against displaying DW_AT_comp_dir for pre-DWARF5 since I figure it is better for readelf to minimally interpret debug info. binutils/ PR 29948 * dwarf.c (display_debug_lines_decoded): Display the given directory entry 0 for DWARF5.

2022-12-06Get rid of SEC_ELF_RENAMEAlan Modra1-2/+7
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. Ld input object files always have BFD_DECOMPRESS set. bfd/ * compress.c (bfd_convert_section_size): Rename to.. (bfd_convert_section_setup): ..this. Handle objcopy renaming of compressed/decompressed debug sections. * elf.c (_bfd_elf_make_section_from_shdr): Only rename zdebug input for linker. (elf_fake_sections): Don't handle renaming of debug sections for objcopy here. * section.c (SEC_ELF_RENAME): Delete. * bfd-in2.h: Regenerate. binutils/ * objcopy.c (setup_section): Call bfd_convert_section_setup. Don't call bfd_convert_section_size.
2022-12-06Compression header enumAlan Modra1-8/+8
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. (enum compression_type): New. Use it throughout file. * elf.c (_bfd_elf_make_section_from_shdr): Replace uses of ELFCOMPRESS_ZLIB and ELFCOMPRESS_ZSTD with ch_compress_zlib and ch_compress_zstd. * bfd-in2.h: Regenerate. binutils/ * readelf.c (process_section_headers, dump_section_as_strings), (dump_section_as_bytes, load_specific_debug_section): Replace uses of ELFCOMPRESS_ZLIB and ELFCOMPRESS_ZSTD with ch_compress_zlib and ch_compress_zstd.

2022-12-05opcodes/mips: use .word/.short for undefined instructionsAndrew Burgess10-34/+34
While working on disassembler styling for MIPS, I noticed that undefined instructions are printed by the disassembler as raw number with no assembler directive prefix (e.g. without .word or .short). I think adding something like .word, or .short, helps to make it clearer the size of the value that is being displayed, and is inline with what many of the other libopcode disassemblers do. In this commit I've added the .word and .short directives, and updated all the tests that I spotted that failed as a result.

2022-12-01binutils: improve holes detection in .debug_loclists.Clément Chigot1-14/+33
The previous warnings about holes in .debug_loclists sections don't take into account the headers of each CU and could include the locviews if they precede the loclist. The following warning can be triggered between two CU. ... <previous CU views> ... 0000001d <End of list> 0000002a v000000000000000 v000000000000000 location view pair 0000002c v000000000000000 v000000000000000 location view pair readelf: Warning: There is a hole [0x1e - 0x2e] in .debug_loclists section. 0000002e v000000000000000 v000000000000000 views at 0000002a for: ... But [0x1e - 0x2a] corresponds to the CU header and [0x2a - 0x2e] are the locviews.

This extends the commit 4581a1c7d304 fix to more targets, which hardens BFD a little. I think the real underlying problem was the bfd_canonicalize_reloc call in load_specific_debug_section which passed a NULL for "symbols". Fix that too.

2022-11-23Don't use "long" in readelf for file offsetsAlan Modra5-499/+532
The aim here is to improve readelf handling of large 64-bit object files on LLP64 hosts (Windows) where long is only 32 bits. The patch changes more than just file offsets. Addresses and sizes are also changed to avoid "long". Most places get to use uint64_t even where size_t may be more appropriate, because that allows some overflow checks to be implemented easily (*alloc changes). * dwarf.c (cmalloc, xcmalloc, xcrealloc, xcalloc2): Make nmemb parameter uint64_t. * dwarf.h: Update prototypes. (struct dwarf_section): Make num_relocs uint64_t. * elfcomm.c (setup_archive): Update error format. * elfcomm.h (struct archive_info): Make sym_size, longnames_size, nested_member_origin, next_arhdr_offset uint64_t. * readelf.c (struct filedata): Make archive_file_offset, archive_file_size, string_table_length, dynamic_addr, dynamic_nent, dynamic_strings_length, num_dynamic_syms, dynamic_syminfo_offset uint64_t.
