--- Comment #9 from Uroš Bizjak <ubizjak at gmail dot com> --- (In reply to Jakub Jelinek from comment #5) > The problem is that those builtins are expanded into RTL using SMIN/SMAX RTL > codes, and those are documented to be undefined in that case: VM variants of minss and maxss should receive the same treatment as their pure vector counterparts minps and maxps. I have a prototype patch, but I have lost myself in the maze of DEFINE_SUBSTs in vector patterns.
