Abstract: The present invention comprises a computer-based system and method for generating meaningful symbolic debug information in translator-based software compilation systems. The present invention includes a translator, a compiler, a merger, and a debugger. The compiler and translator each generate symbolic debug information for a source code. The merger combines the debug information generated by the compiler and translator into a final debug information. The final debug information completely and accurately describes the source code. The debugger uses the final debug information to completely and accurately display the original source code, and to efficiently and effectively use actual variable and function names (from the original source code) when working with variables and functions.

Abstract: The present invention is directed to computer software compilation systems and methods which support run-time data type identification of objects in computer programming languages which support polymorphism. The present invention comprises translators, compilers, and debuggers. The compiler and translator store modified debug information in an object code file. The modified debug information contains information regarding either multiple virtual tables or concatenated virtual tables. A debug lookup table is constructed from the modified debug information. The debugger uses the debug lookup table to determine the actual data types of the objects, and to completely and accurately display and modify the objects' contents. Also, innovative type inquiry operators reference the concatenated virtual tables to determine the actual data types of the objects during run-time. The operation of the compiler, translator, and debugger is transparent to computer programmers and operators.

Abstract: A computer software compiler system and method for distributing a machine independent computer program, created on a native computer platform, to heterogeneous target computer platforms. The system is comprised of a producer component and one or more installer components. The producer component receives the machine independent computer program as input and generates a compiler intermediate representation in a machine independent manner according to an HPcode-Plus compiler intermediate language. The compiler intermediate representation is architecture neutral and represents an architecture neutral distribution format (ANDF). The compiler intermediate representation is distributed to heterogeneous target computer platforms where the installer components reside.

Abstract: A computer software compiler system and method for distributing a machine independent computer program, created on a native computer platform, to heterogeneous target computer platforms. The system comprises installer components which exist on heterogeneous target computer platforms. The installers receive a compiler intermediate representation of the machine independent computer program. The compiler intermediate representation is architecture neutral and represents an architecture neutral distribution format. The installers translate the compiler intermediate representation to object code representations according to an HPcode-Plus compiler intermediate language. The installers operate in a machine dependent manner such that the object code representations are architecture dependent, or machine dependent, on the target computer platforms.

Abstract: A computer software compiler system and method for distributing a machine independent computer program, created on a native computer platform, to heterogeneous target computer platforms. The system comprises a producer which receives the machine independent computer program as input and which generates compiler intermediate representation. The system operates in a machine independent manner according to an HPcode-Plus compiler intermediate language. Thus, the compiler intermediate representation is machine independent and represents an architecture neutral distribution format (ANDF). The compiler intermediate representation, being architecture neutral, can be distributed to heterogeneous target computer platforms. At the heterogeneous target computer platforms, the compiler intermediate representation can be translated in a machine dependent manner into object code representations such that the object code representations are architecture dependent, or machine dependent, on the target computer platforms.
