Abstract: A handle for a trace is provided that is memory indifferent. The handle i s created using contents of the trace rather than memory location of the tra ce. This enables the trace to be easily identified in subsequent runs of an application associated with the trace.

Abstract: Emulation of source machine instructions is provided in which target machine CPU condition codes are employed to produce emulated condition code settings without the use, encoding or generation of branching instructions.

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