The following patch fixes the PR for new set of options. The details of the problem can be found on http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60650The patch affects a sensitive part for LRA. Therefore I bootstrapped and tested it on x86-64, aarch64, arm, s390, and Ppc64. The results look ok.
x86/x86-64 SPEC2000 testing shows no visible effect on performance and code size.
