Abstract

Instrumentation is extensible because the language construct to be instrumented and the particular instrumentation desired for the language construct can be provided to the compiler for each individual compilation using input provided during compilation of a program using a dynamic analyzer. The dynamic analyzer can identify the programming language construct to be instrumented and the instrumentation to be inserted into the code. The dynamic analyzer can analyze the data that is collected.

Claims

1. An extensible instrumentation system comprising:

an instrumenting program module of a compiler configured to;

receive a representation of a program for compilation, the representation of the program comprising a programming language construct;

receive a dynamic analyzer, the dynamic analyzer;

identifying a programming language construct in the representation of the program code; and

identifying instrumentation code to be inserted into the representation of the program for the programming language construct; and

insert the instrumentation code into the representation of the program.

2. The system of claim 1, wherein the dynamic analyzer is one of an extensible set of dynamic analyzers.

3. The system of claim 1, wherein the dynamic analyzer is provided to the instrumenting programming module at compilation of the program.

4. The system of claim 1, wherein the dynamic analyzer provides instrumentation to insert into the representation of the program for the programming language construct.

5. The system of claim 4, wherein the instrumentation comprises a call to a programming language construct.

6. The system of claim 5, wherein the programming language construct accesses a table for storing dynamic analysis information.

7. A method comprising:

providing to a processor configured to instrument a program;

a program to be instrumented;

a dynamic analyzer, the dynamic analyzer;

identifying a programming language construct in the program;

identifying instrumentation code to be inserted into a representation of the program; and

inserting the instrumentation code into the representation of the program.

8. The method of claim 7, further comprising:

providing to the processor a dynamic analyzer, the dynamic analyzer implementing an API.

9. The method of claim 8, wherein the dynamic analyzer identifies a method, a call to which is inserted into the representation of the program.

10. The method of claim 9, wherein the method accesses a table for storing dynamic analysis information.

11. The method of claim 7, wherein dynamic analysis information is collected when the program is run.

12. The method of claim 7, wherein an additional dynamic analyzer can be provided to the processor, thereby extending a set of instrumentations to be performed without reprogramming the instrumenting program module, the instrumenting program module comprising a compiler.

13. A device comprising:

a memory;

a processor connected to the memory, the processor configured to;

receive by a compiler extensible instrumentation instructions for a programming language construct of a program; and

insert the extensible instrumentation instructions into a representation of the program, the instructions collecting dynamic analysis information upon execution of a compiled binary generated from the program.

14. The device of claim 13, wherein the extensible instrumentation instructions are provided by one of a plurality of dynamic analyzers.

15. The device of claim 13, wherein the extensible instrumentation instructions identify a programming language construct to instrument.

16. The device of claim 13, wherein the extensible instrumentation instructions identify the instrumentation code to insert into the representation of the program.

17. The device of claim 13, wherein the instructions inserted into the representation of the source code comprise a call to a programming language construct.

18. The device of claim 13, wherein instrumentations performed on a programming language construct are extensible without reprogramming the compiler.

19. The device of claim 14, wherein the set of dynamic analyzers are extensible.

20. The device of claim 19, wherein the set of dynamic analyzers are extensible by generating an additional dynamic analyzer.
