Method, apparatus and computer programmed product for binary re-optimization using a high level language compiler

An apparatus having a central processing unit (CPU) and a memory coupled to said CPU for converting, by a high level language compiler, a first binary executable that executes within a first application binary interface (ABI) environment to a second binary executable that executes within a second ABI environment, said apparatus comprises:

• a binary disassembler mechanism configured to convert said first executable binary executable to an intermediate representation;
• a compiler approximation mechanism configured to approximate the state of the compiler used to create said first binary executable, at least partially based on annotation information;
• an intermediate representation normalization mechanism configured to remove an architectural related optimization from the first binary executable based on the approximation by the compiler approximation mechanism, wherein said intermediate representation normalization mechanism further comprises a register virtualization mechanism configured to remove register availability limitations from within said intermediate representation;
• an intermediate representation optimizer mechanism configured to optimize said intermediate representation for said second ABI environment, at least partially based on an execution profile;
• and
• a code generation mechanism configured to generate said second binary executable using said intermediate representation, said intermediate representation optimized for said second ABI environment.

A computer program product comprising:

• a computer usable storage medium having computer readable code embodied therein for causing a computer to convert, by a high level language compiler, a first binary executable that executes within a first application binary interface (ABI) environment to a second binary executable that executes within a second ABI environment, said computer readable code comprising:
• computer readable program code configured to cause said computer to effect a binary disassembler mechanism configured to convert said first binary executable to an intermediate representation;
• computer readable program code configured to cause said computer to approximate the state of the compiler used to compile said first binary executable, at least partially based on annotation information;
• computer readable program code configured to cause said computer to effect an intermediate representation normalization mechanism configured to remove an architectural related optimization based on the approximation of the state of the compiler used to compile the first binary executable;
• computer readable program code configured to cause said computer to effect an intermediate representation optimizer mechanism configured to optimize said intermediate representation for said second ABI environment, at least partially based on an execution profile;
• computer readable program code configured to cause said computer to effect a code generation mechanism configured to generate said second binary executable using said intermediate representation optimized for said second ABI environment;
• and
• wherein the intermediate representation normalization mechanism comprises computer readable program code configured to cause said computer to effect a register virtualization mechanism configured to remove register availability limitations from within said intermediate representation.
