; This testcase was distilled from 132.ijpeg. Bsaically we cannot fold the ; load into the sub instruction here as it induces a cycle in the dag, which ; is invalid code (there is no correct way to order the instruction). Check ; that we do not fold the load into the sub. ; RUN: llvm-as < %s | llc -march=x86 | not grep sub.*GLOBAL @GLOBAL = external global i32 ; <i32*> [#uses=1] define i32 @test(i32* %P1, i32* %P2, i32* %P3) { %L = load i32* @GLOBAL ; <i32> [#uses=1] store i32 12, i32* %P2 %Y = load i32* %P3 ; <i32> [#uses=1] %Z = sub i32 %Y, %L ; <i32> [#uses=1] ret i32 %Z }
