; The purpose of the test case is to ensure that a spill that happens during
|
|
; intermediate calculations for a comparison performed in a GPR spills the
|
|
; full register. Some i32 comparisons performed in GPRs use code that uses
|
|
; the full 64-bits of the register in intermediate stages. Spilling such a value
|
|
; as a 32-bit value is incorrect.
