This is the other option, eliminate dead PHIs. compiling all of GCC .c files at -O3, it finds a total of 12 instances of dead phis, and 3 of those were "extra" ones made dead by elimination of the original dead PHI. This patch has not yet been bootstrapped and fully tested, its ongoing now. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37102
