Abstract: Embodiments of the invention provide systems and methods for handling internal compiler errors encountered during compilation of a computer program without breaking the compilation. Implementations of a computer-implemented compiler system include a compiler driver, configured to compile a computer program according to a set of compiler settings, and a number of compiler components, each corresponding to a portion of the computer program. Each compiler component is configured to detect an internal compiler error during compilation of the component; identify a recovery plan having a recovery target and at least one recovery setting; and direct the driver to continue compiling the computer program according to the recovery plan, such that the compilation recompiles from the recovery target and according to a modified set of compiler settings according to the at least one recovery setting.

Abstract: Apparatus, methods and computer program products are disclosed for a high level language compiler that includes a binary re-optimization capability. This re-optimization capability inputs a binary executable and outputs a binary module optimized for a target computer system. The binary module can be linked to create an optimized binary executable. This capability is provided by adding a front end segment to the compiler that reads the binary executable and creates an intermediate representation of the binary executable. This intermediate representation is normalized to remove prior optimization artifacts and to virtualize register usage. The intermediate representation is then optimized for a target computer system resulting in a binary module that can be linked to make a binary executable that is optimized for the target computer.
