--- Comment #3 from Matt Breedlove <breedlove.matt at gmail dot com> --- Created attachment 36166 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=36166&action=edit Patch to bypass sys_siglist and disable stpcpy builtin during bootstrap I'm currently using this patch which overrides sys_siglist detection in addition to the stpcpy built-in when building libiberty which prevents lto bootstrapping. sys_siglist causes failures in both slim and fat lto bootstraps in the later stages while the stpcpy issue remains present only within slim bootstrapping.
