[Please cc me and Segher on PowerPC / AIX patches.] I bootstrapped successfully with the patch and ran the testsuite.
Without patch: https://gcc.gnu.org/ml/gcc-testresults/2016-11/msg00186.html With patch: https://gcc.gnu.org/ml/gcc-testresults/2016-11/msg00233.html Not exactly the same revision, but close enough and no differences. The patch doesn't break anything, but we still need to understand if it is correct. Thanks, David
