Author: kib Date: Thu Mar 7 20:40:39 2019 New Revision: 344898 URL: https://svnweb.freebsd.org/changeset/base/344898 Log: Disable WITH_RETPOLINE on stable/12. It is known that clang 7 generates broken ifunc calls when retpoline is enabled. Since libc uses ifuncs, mark WITH_RETPOLINE as always broken and disabled. To be removed after clang 8 MFC. This is a direct commit to the branch.
