LAYERED VECTOR ARCHITECTURE COMPATIBILITY FOR CROSS-SYSTEM PORTABILITY

An application that includes intrinsics defined in one architecture is to execute without change on a different architecture. Program code that depends on vector element ordering is obtained, and that program code is part of an application including one or more intrinsics. The one or more intrinsics are mapped from a first system architecture for which the application was written to a second system architecture. One or more operations of the program code are then converted from a first data layout to a second data layout. The application, including the mapped intrinsics and the converted data layout, is to be executed on a processor of the different architecture.
