Binary translation using raw binary code with compiler produced metadata

Abstract

A method, system, and computer-readable medium for binary translation cause a binary translator to combine raw binary code and compiler-produced metadata associated with a compiled program module. The binary translator is caused to further reconcile, using the compiler-produced metadata, original compiler-produced control flow information with how lower-level machine instructions comprise a control flow in the raw binary code, and original compiler-produced aliasing information with how lower-level machine instructions access the memory locations described by the aliasing information according to predetermined criteria. The binary translator further caused to prevent, copy propagation of values in temporary variables for decimal computations beyond offsets in the machine instructions where the temporary variables are killed. The binary translator further caused to remove identified dead store instructions, and to generate a new compiled program module comprising an optimized version of the compiled program module having strict compatibility to an original version of the compiled program module.
