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