From: Maciej W. Rozycki Date: Wed, 29 Jul 2020 19:56:41 +0000 (+0100) Subject: MIPS/LD: Set symtab's `sh_info' correctly for IRIX emulations X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3f1b17bbf022a34f92f3dc32d742e4901816708e;p=binutils-gdb.git MIPS/LD: Set symtab's `sh_info' correctly for IRIX emulations Correct ELF linker code so as to set the `sh_info' value of the static symbol table section according to the section symbols vs other symbols split where required by the selection of the IRIX compatibility mode for MIPS target. Add a `elf_backend_elfsym_local_is_section' hook for that purpose, returning TRUE if it is only STB_LOCAL/STT_SECTION symbols that are to be considered local for the purpose of this split rather than all STB_LOCAL symbols. We do it already in generic ELF code, and have done it since 1993, with the `elf_backend_sym_is_global' hook, affecting GAS and `objcopy', so these tools produce correct ELF output in the IRIX compatibility mode, however if such output is fed as input to `ld -r', then the linker's output is no longer valid for that mode. The relevant changes to generic ELF code are: commit 062189c6eab72c7ba1bab1cf30fdb27d67a7d668 Author: Ian Lance Taylor Date: Thu Nov 18 17:12:47 1993 +0000 and: commit 6e07e54f1b347f885cc6c021c3fd912c79bdaf55 Author: Ian Lance Taylor Date: Thu Jan 6 20:01:42 1994 +0000 (split across two GIT commits likely due to repository conversion peculiarities). The `elf_backend_sym_is_global' hook however operates on BFD rather than ELF symbols, making it unsuitable for the ELF linker as the linker does not convert any symbol tables processed into the BFD format. Converting the hook to operate on ELF symbols would in principle be possible, but it would still require a considerable rewrite of `bfd_elf_final_link' to adapt to the interface. Therefore, especially given that no new use for the IRIX compatibility mode is expected, minimize changes made to the ELF linker code and just add an entirely new hook, and wire it in the o32 and n32 MIPS backends accordingly; the n64 backend never uses the IRIX compatibility mode. Since we have no coverage here at all add suitable GAS, LD and `objcopy' test cases to the relevant testsuites to keep these tools consistently verified. bfd/ * elf-bfd.h (elf_backend_data): Add `elf_backend_elfsym_local_is_section' member. * elfxx-target.h (elf_backend_elfsym_local_is_section): New macro.
