Abstract

A method and related system of dynamic compiler resolution. Some of the illustrative embodiments are a computer-implemented method comprising compiling a source file containing an application program (the compiling creates a destination file containing a compiled version of the application program), and inserting in the compiled version of the application program a series of commands that (when executed at run time of the application program) generate an optimized code portion using a value available at run time.

Claims

1. A computer-implemented method comprising:

compiling a source file containing an application program, the compiling creates a destination file containing a compiled version of the application program; and

inserting in the compiled version of the application program a series of commands that, when executed at run time of the application program, generate an optimized code portion using a value available at run time.

2. The computer-implemented method as defined in claim 1 wherein compiling further comprises compiling a source file containing human-readable source code of the application program.

3. The computer-implemented method as defined in claim 1 wherein compiling creates the compiled version of the application program that is executable.

4. The computer-implemented method as defined in claim 3 wherein compiling creates the compiled version of the application program that is directly executable by a processor.

5. The computer-implemented method as defined in claim 3 wherein compiling creates the compiled version of the application program executable on a processor by way of an interpreter.

6. The computer-implemented method as defined in claim 1 further comprising, after inserting, replacing the series of commands with the optimized code portion.

7. The computer-implemented method as defined in claim 1 wherein the compiling and inserting take place prior to execution of the application program.

8. The computer-implemented method as defined in claim 1 wherein the compiling and inserting take place on a first portion of the application program while a second portion of the application program is executed.

9. A computer-readable medium storing a compiler program that, when executed by a processor, performs a method comprising:

compiling source code of an application program to create a compiled version of the application program; and

inserting in the compiled version of the application program a series of commands that, when executed at run time of the application program, generate optimized code using a value available at run time.

10. The computer-readable medium as defined in claim 9 wherein compiling further comprises compiling to create an executable version of the application program.

11. The computer-readable medium as defined in claim 10 wherein compiling further comprises compiling to create the compiled version of the application program that is directly executable by a processor.

12. The computer-readable medium as defined in claim 10 wherein compiling further comprises compiling to create the compiled version of the application program that is platform independent and executable on a processor by way of an interpreter.

13. The computer-readable medium as defined in claim 9 wherein compiling further comprises the source code of the application program that is human readable.

14. The computer-readable medium as defined in claim 9 wherein the method further comprises, after inserting, replacing the series of commands in the compiled version of the application program with the optimized code.

15. The computer-readable medium as defined in claim 9 wherein the compiling and inserting take place prior to execution of the application program.

16. The computer-readable medium as defined in claim 9 wherein the compiling and inserting takes place on a first portion of the application program while a second portion of the application program is executed.

17. A system comprising:

a memory, wherein the memory contains a source file of an program; and

a first processor coupled to the memory;

wherein the first processor is configured to compile the program of the source file to create a compiled program, and wherein the processor is configured to insert in the compiled program a series of commands that, when executed at run time, generate an optimized code portion using a value available at run time.

18. The system as defined in claim 17 wherein the source file in the memory is a human readable source code file for the application program.

19. The system as defined in claim 17 wherein the compiled version of the program in the destination file is executable on the processor by way of an interpreter program.

20. The system as defined in claim 17 wherein the compiled version of the program in the destination file is directly executable on the processor.

21. The system as defined in claim 17 further comprising:

a second processor coupled to the memory and the first processor;

wherein the second processor is configured to directly execute at least one command of the compiled program.

22. The system as defined in claim 17 further comprising wherein the first processor is configured to create a first portion of the compiled program while a second portion of the compiled program executes on one or both the first and second processors.

23. The system as defined in claim 17 further comprising wherein the first processor is configured to create the compiled program prior to execution of any portion of the compiled program.
