commit994b251328Author: H.J. Lu <hjl.tools@gmail.com> Date: Sun Jan 17 20:01:16 2021 -0800 ld/elf: Ignore section symbols when matching linkonce with comdat ignored section symbols when comparing symbols in 2 sections. Since all references to debugging sections are done with section symbols, symbols in debugging sections are ignored and we fail to match symbols in comdat debugging sections. Also .gnu.debuglto_.debug_* sections aren't treated as debugging sections. 1. Treate .gnu.debuglto_.debug_ section as debugging section unless it is marked with SHF_EXCLUDE. 2. Revert commit994b251328in elf_create_symbuf. 3. Ignore section symbols only when matching non-debugging sections or linkonce section with comdat section. bfd/ PR ld/27590 * elf.c (_bfd_elf_make_section_from_shdr): Treate .gnu.debuglto_.debug_ section as debugging section unless it is marked with SHF_EXCLUDE. * elflink.c (elf_create_symbuf): Revert commit994b251328.
