| ; 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-upgrade < %s | llvm-as | llc -march=x86 | not grep sub.*GLOBAL |
| |
| %GLOBAL = external global int |

| int %test(int* %P1, int* %P2, int* %P3) { |
| %L = load int* %GLOBAL |
| store int 12, int* %P2 |
| %Y = load int* %P3 |
| %Z = sub int %Y, %L |
| ret int %Z |
