ISA bridging including support for call to overidding virtual functions

摘要

Methods, apparatuses and storage medium associated with ISA bridging with support for virtual functions, are disclosed. In embodiments, at least one computer-readable storage medium may include instructions configured to enable a target device with a target ISA, in response to execution, to provide an ISA bridging layer to the target device to facilitate a library service of a library of the target device to call a virtual function of the library, while servicing an application operating on the target device, where the application has an overriding implementation. The ISA bridging layer may include a loader configured to load the application for execution, and as part of loading the application, detect the virtual function and modify a virtual function table of the application to enable the call. Other embodiments may be disclosed or claimed.

1. At least one computer-readable non-transitory storage medium comprising:
instructions configured to enable a target device with a target instruction set architecture, in response to execution of the instructions, to provide an instruction set architecture bridging layer to the target device to facilitate a library service of a library of the target device to call a virtual function of the library, while servicing an application operating on the target device; wherein the library service is implemented for the target instruction set architecture, and the application is implemented at least partially for a source instruction set architecture and includes a class with an overriding implementation of the virtual function; and wherein the instruction set architecture bridging layer includes a loader configured to load the application for execution, and the loader, as part of loading the application,
detect the overriding implementation of the virtual function, and modify a virtual function table of the class to enable, in response to the call, execution control be transferred back across the source and target instruction set architectures to the overriding implementation of the virtual function.
