In one embodiment, a processor includes an instruction decoder to receive a first instruction having a prefix and an opcode and to generate, by an instruction decoder of the processor, a second instruction executable based on a condition determined based on the prefix, and an execution unit to conditionally execute the second instruction based on the condition determined based on the prefix.

Conditional execution support for ISA instructions using prefixes

Methods and systems to compile a code module to permit a caller routine to pass a parameter to a callee routine of a separately compiled code module, and to permit a callee routine to receive a parameter from a caller routine of the separately compiled code module, through multiple interfaces. Interfaces may include an interface by convention and an alternate interface. A caller routine may be configured to pass a parameter through an alternate interface and call to an alternate entry point of a callee routine. An associated stub routine may be configured to pass the parameter through an interface by convention and to call to a conventional entry point of the callee routine. If the callee routine includes a corresponding alternate entry point, the caller routine may be linked to the alternate entry point. Otherwise, the callee routine may be linked to the callee routine through the stub routine.

Methods and systems to implement non-ABI conforming features across unseen interfaces

A computer-implemented method analyzes a source code segment which is to be compiled for execution by any one of several different processor types. The method determines whether a performance advantage would be achieved by generating a customized version of object code that can be executed by one of the processor types compared with generating a non-customized version. If a performance advantage would be achieved, the method generates at least one customized object code version and a non-customized version for the source code segment, and it generates a control section that causes one of the object code versions to be called during execution of the object code in accordance with an executing processor's processor type. If no performance advantage would be achieved, the method generates a non-customized version of the object code that can be executed by any of the different processor types.
