Disassembly of section .plt:
ELF: Don't generate unused section symbols 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.

ELF: Don't generate unused section symbols 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.

ELF: Don't generate unused section symbols 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.
