Just-ahead-of-time compilation

In a computing environment comprising a runtime compilation, a method of compiling functions, the method comprising:

• determining that a function of an application has been called;
• analyzing annotations to the application program, the annotations comprising a postdominance graph including one or more functions of the application program;
• using the postdominance graph, identifying one or more postdominance relationships between the function and the entry of one or more other functions;
• assigning the one or more other functions to be pre-compiled based on the postdominance relationship.

In a computing environment, a computer readable medium comprising computer executable instructions that when executed by a processor are configured to cause the following to be performed:

• determining that a function of an application has been called;
• as a result of determining that the function has been called, starting a compiler, wherein the compiler is configured to read in the function;
• at the compiler decomposing the function into basic blocks,
• constructing a control flow graph, the control flow graph representing the basic blocks in the control flow graph;
• using the control flow graph, determining one or more postdominance relationships between the function and the entry to one or more other functions;
• assigning the one or more other functions to be pre-compiled by at least one of a different processor or virtual processor than a processor compiling the function, based on the postdominance relationship.
