2020-02-02ELF: Add support for unique section ID to assemblerH.J. Lu4-6/+33
Clang's integrated assembler supports multiple section with the same name: .section .text,"ax",@progbits,unique,1 nop .section .text,"ax",@progbits,unique,2 nop "unique,N" assigns the number, N, as the section ID, to a section. The valid values of the section ID are between 0 and 4294967295. It can be used to distinguish different sections with the same section name. This is useful with -fno-unique-section-names -ffunction-sections. -ffunction-sections by default generates .text.foo, .text.bar, etc. Using the same string can save lots of space in .strtab. This patch adds section_id to bfd_section and reuses the linker internal bit in BFD section flags, SEC_LINKER_CREATED, for assmebler internal use to mark valid section_id. It also updates objdump to compare section pointers if 2 sections comes from the same file since 2 different sections can have the same section name. bfd/ PR gas/25380 * bfd-in2.h: Regenerated. * ecoff.c (bfd_debug_section): Add section_id. * section.c (bfd_section): Add section_id.

2020-01-31OOM in setup_groupAlan Modra2-3/+10
We alloc, seek and read using section sizes in object files. Fuzzed objects can have silly sizes, but that's OK if the system supports memory over-commit. The read fails because we hit EOF and that usually results in a graceful exit. But if we memset before the read then the invalid size results in attempting to write to a huge number of memory pages, and an eventual Out Of Memory after probably swapping like crazy. So don't memset. There really isn't a need to clear the section contents anyway. All bytes are written with a good object file by the read and following loop converting section index in target order to ELF section header pointer, and the only untidy bytes are the 4 bytes past the group flags when pointers are 8 bytes. Those don't matter but the patch clears them for anyone poking around in a debugger. On error paths it's as good to free section contents as it is to clear them. Noticed when looking at PR4110 fourth test case. PR 4110 * elf.c (setup_group): Don't clear entire section contents, just the padding after group flags. Release alloc'd memory after a seek or read failure.

2020-01-30Identify reproducible builds in 'objdump -p' output for PE filesJon Turney2-5/+86
These are produced by MSVC when the '/Brepro' flag is used. To quote from the PE specification [1]: "The presence of an entry of type IMAGE_DEBUG_TYPE_REPRO indicates the PE file is built in a way to achieve determinism or reproducibility. If the input does not change, the output PE file is guaranteed to be bit-for-bit identical no matter when or where the PE is produced. Various date/time stamp fields in the PE file are filled with part or all the bits from a calculated hash value that uses PE file content as input, and therefore no longer represent the actual date and time when a PE file or related specific data within the PE is produced. The raw data of this debug entry may be empty, or may contain a calculated hash value preceded by a four-byte value that represents the hash value length."

2020-01-15PR25384, PowerPC64 ELFv1 copy relocs against function symbolsAlan Modra2-19/+38
Function symbols of course don't normally want .dynbss copies but with some old versions of gcc they are needed to copy the function descriptor. This patch restricts the cases where they are useful to compilers using dot-symbols, and enables the warning regardless of whether a PLT entry is emitted in the executable. PLTs in shared libraries are affected by a .dynbss copy in the executable. bfd/ PR 25384 * elf64-ppc.c (ELIMINATE_COPY_RELOCS): Update comment. (ppc64_elf_adjust_dynamic_symbol): Don't allow .dynbss copies of function symbols unless dot symbols are present. Do warn whenever one is created, regardles of whether a PLT entry is also emitted for the function symbol. ld/ * testsuite/ld-powerpc/ambiguousv1b.d: Adjust expected output. * testsuite/ld-powerpc/funref.s: Align func_tab. * testsuite/ld-powerpc/funref2.s: Likewise. * testsuite/ld-powerpc/funv1.s: Add dot symbols.
