+; The code generated by sdiv is long and complex and may frequently change.
+; The goal of this test is to make sure the ISel doesn't fail.
+;
+; This program was previously failing to compile when one of the selectcc
+; opcodes generated by the sdiv lowering was being legalized and optimized to:
+; selectcc Remainder -1, 0, -1, SETGT
+; This was fixed by adding an additional pattern in R600Instructions.td to
+; match this pattern with a CNDGE_INT.
