METHOD FOR EMBEDDING SHORT RARE CODE SEQUENCES IN HOT CODE WITHOUT BRANCH-AROUNDS

摘要

The problem of handling exceptionally executed code portions is improved through the practice of embedding handling instructions within other instructions, such as within their "immediate" fields. Such instructions are chosen to have short execution times. Most of the time these instructions are executed quickly without having to include jumps around them. Only rarely are the other portions of these specialized computer instruction needed or used.
