Did you apply the PA ICF aliasing restriction patch from https://gcc.gnu.org/bugzilla/attachment.cgi?id=33843? Without it, the new ipa-icf pass will erroneously attempt alias creation on targets which don't support (it like MACH-O on darwin). The cryptic "ld: illegal text reloc" error is emitted from the darwin linker because the use of "-undefined dynamic_lookup" masks the fact that undefined symbols result from the inappropriate alias creation. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63622#c12
