__bss_start, _end and _edata are defined by linker to mark regions within executables and shared libraries. All references within executables should be locally resolved. This patch doesn't change how their references within shared libraries are resolved. bfd/ PR ld/23162 * elfxx-x86.c (elf_x86_linker_defined): New function. (_bfd_x86_elf_link_check_relocs): Use it to mark __bss_start, _end and _edata locally defined within executables. ld/ PR ld/23162 * testsuite/ld-elf/pr23162.map: New file. * testsuite/ld-elf/pr23162.rd: Likewise. * testsuite/ld-elf/pr23162a.c: Likewise. * testsuite/ld-elf/pr23162b.c: Likewise. * testsuite/ld-elf/shared.exp: Run PR ld/23162 tests.
