; Test that spill and reloads use the dsp "variant" instructions. We use -O0
; to use the simple register allocator.
; To test the micromips output, we have to take a round trip through the
; object file encoder/decoder as the instruction mapping tables are used to
; support micromips.
; FIXME: We should be able to get rid of those instructions with the variable
; value registers.
