George Burgess IV 59fe6640ec [MemorySSA] Consider def-only BBs for live-in calculations. ... If we have a BB with only MemoryDefs, live-in calculations will ignore it. This means we get results like this: define void @foo(i8* %p) { ; 1 = MemoryDef(liveOnEntry) store i8 0, i8* %p br i1 undef, label %if.then, label %if.end if.then: ; 2 = MemoryDef(1) store i8 1, i8* %p br label %if.end if.end: ; 3 = MemoryDef(1) store i8 2, i8* %p ret void } ...When there should be a MemoryPhi in the `if.end` BB. This patch fixes that behavior. llvm-svn: 263991		2016-03-21 21:25:39 +00:00
