Quentin Colombet 83f743a4d5 [DAGCombiner] Reapply load slicing (192471) with a test that explicitly set sse4.2 support. ... This should fix the buildbots. Original commit message: [DAGCombiner] Slice a big load in two loads when the element are next to each other in memory and the target has paired load and performs post-isel loads combining. E.g., this optimization will transform something like this: a = load i64* addr b = trunc i64 a to i32 c = lshr i64 a, 32 d = trunc i64 c to i32 into: b = load i32* addr1 d = load i32* addr2 Where addr1 = addr2 +/- sizeof(i32), if the target supports paired load and performs post-isel loads combining. One should overload TargetLowering::hasPairedLoad to provide this information. The default is false. <rdar://problem/14477220> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192476 91177308-0d34-0410-b5e6-96231b3b80d8		2013-10-11 18:29:42 +00:00
