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