# FIXME: Assert if run to end
# The V_MFMA_F32_32X32X1F32_vgprcd_e64 as written requires 66 VGPRs
# to allocate, but the register budget (with a forced AGPR usage and
# occupancy 4) permits 64 VGPRs and 64 AGPRs, so we need to force a
# copy from VGPR to AGPR. The minimal copies required for this need to
# copy %3 and %4 V_MOV_B32s into temporary AGPRs for use by the MFMA.
# Previously we would attempt a register subclass based split, but
# immediately rematerialize the V_MOV_B32 into the new temporary
# register, defeating the point of introducing the split. The
# allocation would fail since it's 2 registers short.
