* my recent change caused a failure in a bswap testcase, because it changedChris Lattner2007-03-031-48/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the order that instcombine processed instructions in the testcase. The end result is that instcombine finished with: define i16 @test1(i16 %a) { %tmp = zext i16 %a to i32 ; <i32> [#uses=2] %tmp21 = lshr i32 %tmp, 8 ; <i32> [#uses=1] %tmp5 = shl i32 %tmp, 8 ; <i32> [#uses=1] %tmp.upgrd.32 = or i32 %tmp21, %tmp5 ; <i32> [#uses=1] %tmp.upgrd.3 = trunc i32 %tmp.upgrd.32 to i16 ; <i16> [#uses=1] ret i16 %tmp.upgrd.3 } which can't get matched as a bswap. This patch makes instcombine more sophisticated about removing truncating casts, allowing it to turn this into: define i16 @test2(i16 %a) { %tmp211 = lshr i16 %a, 8 %tmp52 = shl i16 %a, 8 %tmp.upgrd.323 = or i16 %tmp211, %tmp52 ret i16 %tmp.upgrd.323 } which then matches as bswap. This fixes bswap.ll and implements InstCombine/cast2.ll:test[12]. This also implements cast elimination of add/sub. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34870 91177308-0d34-0410-b5e6-96231b3b80d8
