--- Comment #8 from Alan Modra <amodra at gcc dot gnu.org> --- Author: amodra Date: Thu Oct 19 23:06:20 2017 New Revision: 253914 URL: https://gcc.gnu.org/viewcvs?rev=253914&root=gcc&view=rev Log: PR82575, lto debugobj references __gnu_lto_slim, ld test liblto-17 fails If __gnu_lto_slim is global, undefined, default visibility in the early debug object, then it finds its way into .dynsym when creating shared libraries. __gnu_lto_slim in a symbol table (.dynsym or .symtab) signals nm and other binutils that the object is an LTO object needing a plugin, but that isn't the case for the ld liblti-17 tests. So, make __gnu_lto_slim hidden to prevent it becoming dynamic. Further, make it weak because some linkers may warn on finding an undefined global non-default visibility symbol. PR lto/82575 * simple-object-elf.c (simple_object_elf_copy_lto_debug_sections): Make discarded non-local symbols weak and hidden.
