Quentin Colombet 30c0f72237 [CodeGenPrepare] Move away sign extensions that get in the way of addressing ... mode. Basically the idea is to transform code like this: %idx = add nsw i32 %a, 1 %sextidx = sext i32 %idx to i64 %gep = gep i8* %myArray, i64 %sextidx load i8* %gep Into: %sexta = sext i32 %a to i64 %idx = add nsw i64 %sexta, 1 %gep = gep i8* %myArray, i64 %idx load i8* %gep That way the computation can be folded into the addressing mode. This transformation is done as part of the addressing mode matcher. If the matching fails (not profitable, addressing mode not legal, etc.), the matcher will revert the related promotions. <rdar://problem/15519855> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200947 91177308-0d34-0410-b5e6-96231b3b80d8		2014-02-06 21:44:56 +00:00
