Note you also need to adjust BOOT_LDFLAGS and TARGET_LDFLAGS. And note that bootstrap with LTO is currently broken, see for example PR41598. -- rguenth at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41691 ^ permalink raw reply [flat|nested] 4+ messages in thread
