A system and method for optimizing the object codes of a computer program is disclosed. The method includes receiving one or more object code units associated with an executable program; identifying, among the object code units, a first program entity and a first set of operations associated with the first program entity and a second program entity and a second set of operations associated with the second program entity, each program entity having an object code segment and an associated address; updating the object code units by inserting a predefined instruction before the first program entity's object code segment and causing the second set of operations to be associated with the predefined instruction if the first program entity's object code segment is identical to the second program entity's object code segment; and combining the updated object code units into the executable program.

Method and system for optimizing an executable program by generating special operations for identical program entities

A system and method for optimizing the object code of a computer program is disclosed. The method includes receiving one or more object code units from the memory; identifying first and second identical program entities in the one or more object code units, wherein each program entity has an object code segment and an associated address; updating the one or more object code units by merging the first identical program entity with the second identical program entity if neither of the first and second program entities is subject to an operation on the respective program entity's address; and linking the updated one or more object code units into an executable program.

Method and system for optimizing an executable program by selectively merging identical program entities

One embodiment of the present invention provides a system for compiling a computer program. During operation, the system receives one or more source code files associated with a computer program at a compiler. Next, the system starts a linker which links object files into an executable program. The system then compiles the one or more source code files into one or more object files. Upon creating each object file, the system sends the object file to the linker without waiting to create the remaining object files.
