Quentin Colombet b60dc81c8b [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> llvm-svn: 192471		2013-10-11 18:01:14 +00:00
