--- Comment #27 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:5fb07870fa4c86f529930bae76689ed5bdfcb192 commit r10-6359-g5fb07870fa4c86f529930bae76689ed5bdfcb192 Author: Jakub Jelinek <ja...@redhat.com> Date: Thu Jan 30 21:32:36 2020 +0100 cgraph: Avoid creating multiple *.localalias aliases with the same name [PR93384] The following testcase FAILs on powerpc64le-linux with assembler errors, as we emit a call to bar.localalias, then .set bar.localalias, bar twice and then another call to bar.localalias. The problem is that bar.localalias can be created at various stages and e.g. ipa-pure-const can slightly adjust the original decl, so that the existing bar.localalias isn't considered usable (different flags_from_decl_or_type). In that case, we'd create another bar.localalias, which clashes with the existing name. Fixed by retrying with another name if it is already present. The various localalias aliases shouldn't be that many, from different partitions they would be lto_priv suffixed and in most cases they would already have the same type/flags/attributes. 2020-01-30 Jakub Jelinek <ja...@redhat.com> PR lto/93384 * symtab.c (symtab_node::noninterposable_alias): If localalias already exists, but is not usable, append numbers after it until a unique name is found. Formatting fix. * gcc.dg/lto/pr93384_0.c: New test. * gcc.dg/lto/pr93384_1.c: New file.
