Abstract

Processor trace systems and methods are described. For example, one embodiment comprises executing instrumented code by a compiler, the instrumented code including at least one call to un-instrumented code. The compiler can determine the at least one call to un-instrumented code is a next call to be executed. A resume tracing instruction can be inserted into the instrumented code prior to the at least one call to the un-instrumented code. The resume tracing instruction can be executed to selectively add processor tracing to the at least one call to the un-instrumented code, and the at least one call to the un-instrumented code can be executed.
