4 # In this test, the VDIVPS takes 38 cycles to write to register YMM3. The first
5 # VADDPS does not depend on the VDIVPS (the WAW dependency is eliminated at
6 # register renaming stage). So the first VADDPS can be executed in parallel to
7 # the VDIVPS. That VADDPS also writes to register XMM3, and the upper half of
8 # YMM3 is implicitly cleared. As a consequence, the definition of YMM3 from the
9 # VDIVPS is killed, and the subsequent VADDPS instructions don't need to wait
10 # for the VDIVPS to complete.
11 # The block reciprocal throughput is limited by the VDIVPS reciprocal throughput
12 # (which is 38 cycles). The sequence of VADDPS can be executed in parallel on
13 # the FPA unit; their latency is "hidden" by the long latency of the VDIVPS.
