# Even though we're building for a 5272, we specify 5307 as our processor type.
# The 5307 instruction set is the same as the 5272 (divide unit & MAC) plus
# the 5272 instruction timings are closer to the 5307 than the other 5200
# series processors (specifically the multiply and divide instructions which
# are all this option really alters).
