2010-11-20On X86, MEMBARRIER, MFENCE, SFENCE, LFENCE are not target memory intrinsics,Duncan Sands
so don't claim they are. They are allocated using DAG.getNode, so attempts to access MemSDNode fields results in reading off the end of the allocated memory. This fixes crashes with "llc -debug" due to debug code trying to print MemSDNode fields for these barrier nodes (since the crashes are not deterministic, use valgrind to see this). Add some nasty checking to try to catch this kind of thing in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119901 91177308-0d34-0410-b5e6-96231b3b80d8
