Abstract

Embodiments of the present invention provide a method and an apparatus for optimizing compilation in a profiling technology. The method for optimizing compilation in a profiling technology of the present invention comprises: obtaining at least two regions by dividing a software control flow diagram, and replacing an instrumentation function comprised in software corresponding to each region with a count operation; and executing the software corresponding to each region on a main thread, when execution of the software corresponding to one region is ended, starting at least one microthread to execute an operation other than the count operation of the instrumentation function comprised in the software corresponding to the region, so as to record information during execution of the software corresponding to the region; where the microthread and a main thread for executing software corresponding to a next region are executed in parallel. The embodiments of the present invention improve execution efficiency during compilation in a profiling technology, thereby solving a problem of low execution efficiency in the prior art.

Description

technical field [0001] Embodiments of the present invention relate to network technology, and in particular to an optimization method and device for contour technology compilation. Background technique [0002] The general practice of modern optimizing compilers is to use profiling technology, which is an important method for collecting program runtime information, including edge profiling, stride profiling, value Contour technology (value profiling) and other forms, among which edge profiling is the most widely used. [0003] The existing Edge Profiling method is to insert instrumentation functions that can calculate the number of executions of each edge on the control flow graph generated at compile time, but the number is the least; the executable file generated in this way will call the instrumentation several times at runtime Function to collect the runtime information of the program and save it in the form of a file. figure 1 It is a schematic diagram of dividing bas...
