; 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.
