Event Code: 0xAB
Mask: 0x02
Category: Execution Events;
Definition: ESP register automatic additions.
Description: This event counts the
number of ESP additions performed automatically by the decoder. A high
count of this event is good, since each automatic addition performed by
the decoder saves a micro-op from the execution units.
To maximize the number of ESP additions performed automatically by the
decoder, choose instructions that implicitly use the ESP, such as PUSH,
POP, CALL, and RET instructions whenever possible.
