; 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 int | |
int %test(int* %P1, int* %P2, int* %P3) { | |

store int 12, int* %P2 | |
%Y = load int* %P3 | |
%Z = sub int %Y, %L | |
