Optimizing assembled code for execution using execution statistics collection, without inserting instructions in the code and reorganizing the code based on the statistics collected

A system for compiling and optimizing execution of a program code, said system comprising:

• means for compiling said program code into assembled code without inserting instructions for execution statistics collection into said assembled code;
• memory means coupled to said compiling means for holding said assembled code for execution;
• a processor coupled to said memory means for executing said assembled code held by said memory means, said processor having an execution environment;
• means, coupled to said processor and to an optimizer, for collecting execution statistics on said assembled code executed by said processor without requiring said instructions for execution statistics collection to be in said assembled code;
• and
• means, including said optimizer, for re-configuring said executed assembled code, said re-configuring means employing said execution statistics collected by said collection means, said re-configuring means outputting a re-configured optimized assembled code.

A computer-implemented method for optimizing assembled code organization for execution on a processor system, without inserting instructions for execution statistics collection into said assembled code, said optimizing method comprising the steps of:

• (a) executing said assembled code on said processor system;
• (b) simultaneous with said step (a), and external to said step (a), accumulating execution statistics on said executed assembled code within said processor system's execution environment;
• and
• (c) automatically re-configuring said executed assembled code organization by providing said execution statistics collected in said step (b) to an optimizer to improve execution performance of said executed assembled code within said processor system's execution environment.

A system for compiling and enhancing execution of a program code, said system comprising:

• means for compiling said program code into assembled code without inserting instructions for execution statistics collection into said assembled code;
• memory means coupled to said compiling means for holding said assembled code for execution;
• a processor coupled to said memory means for executing said assembled code held by said memory means, said processor having an execution environment;
• means, external to the assembled code and coupled to said processor and to an optimizer, for collecting execution statistics on said executed assembled code executed by said processor;
• and
• means, including said optimizer, for re-configuring said executed assembled code, said re-configuring means employing said execution statistics collected by said collection means, said re-configuring means outputting a re-configured optimized assembled code.
