Chandler Carruth d3834e5bef Now that mem2reg understands how to cope with a slightly wider set of ... uses of an alloca, we can pre-compute promotability while analyzing an alloca for splitting in SROA. That lets us short-circuit the common case of a bunch of trivially promotable allocas. This cuts 20% to 30% off the run time of SROA for typical frontend-generated IR sequneces I'm seeing. It gets the new SROA to within 20% of ScalarRepl for such code. My current benchmark for these numbers is PR15412, but it fits the general pattern of IR emitted by Clang so it should be widely applicable. llvm-svn: 187323		2013-07-28 08:27:12 +00:00
