The best idea I could come up with was to check each basic block to see if there are any conditional sets of predicate registers in it and add pred.rel.mutex lines for those registers. If we add pred.rel.mutex lines for all used predicate registers we wind up adding a lot of unneeded pred.rel.mutex statements. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43760
