# perf stat reports an IPC of 2.00 for this block of code.

# All of the vector packed compares from this test are zero idioms.  These zero
# idioms are all detected and removed by the register renamer.  That means, no
# uOp is executed, and there is no RAW dependency for any of the packed
# compares.
