This avoids generating two gep's for common array operations. Before we would generate something like: %tmp = load i32* %X.addr ; <i32> [#uses=1] %arraydecay = getelementptr inbounds [100 x i32]* %A, i32 0, i32 0 ; <i32*> [#uses=1] %arrayidx = getelementptr inbounds i32* %arraydecay, i32 %tmp ; <i32*> [#uses=1] %tmp1 = load i32* %arrayidx ; <i32> [#uses=1] Now we generate: %tmp = load i32* %X.addr ; <i32> [#uses=1] %arrayidx = getelementptr inbounds [100 x i32]* %A, i32 0, i32 %tmp ; <i32*> [#uses=1] %tmp1 = load i32* %arrayidx ; <i32> [#uses=1] Less IR is better at -O0. llvm-svn: 106966
