Running lang_common before garbage collection means slightly less work in garbage collection code, since common symbols should no longer appear there. It does have the side effect of keeping linker script symbols (at least those defined outside of sections) global too, hence some testsuite churn. bfd/ PR 17165 * elf-bfd.h (ELF_COMMON_DEF): Note that this might be true for linker script assignments too. * elflink.c (elf_gc_sweep_symbol): Don't drop ELF_COMMON_DEF syms. (bfd_elf_gc_mark_dynamic_ref_symbol): Similarly. ld/ PR 17165 * ldlang.c (lang_process): Run lang_common before lang_gc_sections. ld/testsuite/ * ld-gc/pr14265.d, * ld-cris/tls-gc-68.d, * ld-cris/tls-gc-69.d, * ld-cris/tls-gc-70.d, * ld-cris/tls-gc-71.d, * ld-cris/tls-gc-75.d, * ld-cris/tls-gc-76.d, * ld-cris/tls-gc-79.d, * ld-mmix/bpo-10.d, * ld-mmix/bpo-11.d: Update.
