I saw some failures of new tgamma tests for ARM. On investigation these appear to be a GCC bug; <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66731> filed. So if you see missing errno settings for tgamma_upward on ARM, or, I think but haven't tested, AArch64, that GCC bug is the cause. -- Joseph S. Myers joseph@codesourcery.com
