摘要： 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.

摘要： The inventive mechanism allows an application to switch modes during its operation, between a compatibility or legacy mode for a previous architecture, and a native mode for a current architecture. The mechanism includes an official function descriptor which describes information for accessing a function which resides in one module. The OFD has a legacy portion is useable by a legacy module and a native portion is useable by a native module. The mechanism also includes a linkage table that resides in a second module which references the function in the first module. The portion of the OFD which corresponds to the mode of the linkage table module is copied into the linkage table. Each portion contains one entry that corresponds to an address location of the function, and another entry that is a value for a register which refers to the data segment corresponding to the load module containing the function. The information in the OFD depends on whether the function is a legacy function or a native function.

摘要： A computer-implemented method of switching contexts in a processor is provided. The processor includes a register stack (RS) that has first and second portions. The processor includes a register stack engine (RSE) to exchange information, in one of instruction execution dependent and independent modes between the second portion and the storage area. The computer implemented method of switching contexts includes the following steps: It is determined whether an interrupt occurred; a first register (IFM) configured to store a content of a second register (CFM) is invalidated, the CFM is configured to store control information related to the first portion; it is determined whether an interrupt handler needs to access the RS; and if so, the IFM is validated, the content of the CFM is copied to the IFM, and RSE is caused to exchange information between both the first and second portions of the RS and the storage area. On return from interruption, if IFM is validated, CFM is restored from IFM else CFM remains unchanged. The COVER instruction enables lightweight interrupt handling in a processor with a Register Stack.

摘要： 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.
