2013-10-29ld/ELF: refine fake STT_FILE symbol emissionJan Beulich1-16/+18
There's no real need to emit these always: They're needed only if we indeed want to emit a localized symbol. Hence defer emission until we at least did the basic early checks that would lead to no such symbol getting emitted. This in particular avoids emitting such a symbol in the majority of (if not all) "ld -r" cases. I hope my set of cross build tests caught all the test cases needing adjustment - please forgive if I missed a few. bfd/ 2013-10-29 Jan Beulich <jbeulich@suse.com> * elflink.c (struct elf_outext_info): Add field file_sym_done.
