2021-01-07ELF: Don't generate unused section symbolsH.J. Lu1-4/+4
For ELF targets, section symbols are required only for relocations. With -ffunction-sections -fdata-sections, there can be many unused section symbols. Sizes of libstdc++.a on Linux/x86-64 in GCC 11 are With unused section symbols : 39411698 bytes Without unused section symbols: 39227002 bytes The unused section symbols in libstdc++.a occupy more than 180 KB. Add BSF_SECTION_SYM_USED to indicate if a section symbol should be included in the symbol table. The BSF_SECTION_SYM_USED should be set if the section symbol is used for relocation or the section symbol is always included in the symbol table. Add keep_unused_section_symbols to bfd_target to indicate if unused section symbols should be kept. If TARGET_KEEP_UNUSED_SECTION_SYMBOLS is defined as FALSE, unused ection symbols will be removed. Tested on Linux/x86. Other ELF backends need to: 1. Define TARGET_KEEP_UNUSED_SECTION_SYMBOLS to FALSE. 2. Mark used section symbols in assembler backend. 3. Remove unused section symbols from expected assembler and linker outputs. bfd/ PR 27109 * aix386-core.c (core_aix386_vec): Initialize keep_unused_section_symbol to TARGET_KEEP_UNUSED_SECTION_SYMBOLS. * aout-target.h (MY (vec)): Likewise. * binary.c (binary_vec): Likewise. * cisco-core.c (core_cisco_be_vec): Likewise.

2020-07-15x86: avoid attaching suffixes to unambiguous insnsJan Beulich1-18/+18
"Unambiguous" is is in particular taking as reference the assembler, which also accepts certain insns - despite them allowing for varying operand size, and hence in principle being ambiguous - without any suffix. For example, from the very beginning of the life of x86-64 I had trouble understanding why a plain and simple RET had to be printed as RETQ. In case someone really used the 16-bit form, RETW disambiguates the two quite fine.

2018-06-08Define various symbols conditionally in shared librariesAlan Modra1-23/+23
The values of symbols in shared libraries like _end, _edata, and __bss_start are generally not that useful outside of the shared library. This patch defines them conditionally with PROVIDE, since a shared library might need the local value. An example is glibc ld.so local access to "_begin", "_etext" and "_end". (ld.so gains access to the local values by making the references using hidden visibility. That makes the definitions hidden too.) We can't use PROVIDE_HIDDEN in the linker scripts because the shared library might need the value of the symbol in the executable. An example is freebsd libc dynamic access to "_end".

2014-07-16Properly match PLT entry against .got.plt relocationH.J. Lu1-0/+54
Relocations against .got.plt section may not be in the same order as entries in PLT section. It is incorrect to assume that the Ith reloction index against .got.plt section always maps to the (I + 1)th entry in PLT section. This patch matches the .got.plt relocation offset/index in PLT entry against the index in .got.plt relocation table. It only checks R_*_JUMP_SLOT and R_*_IRELATIVE relocations. It ignores R_*_TLS_DESC and R_*_TLSDESC relocations since they have different PLT entries. bfd/ PR binutils/17154 * elf32-i386.c (elf_i386_plt_sym_val): Only match R_*_JUMP_SLOT and R_*_IRELATIVE relocation offset with PLT entry. * elf64-x86-64.c (elf_x86_64_plt_sym_val): Likewise.
