Application binary interface cross compilation

A method for just-in-time cross-compiling compiled binaries of application programs that utilize graphics processing unit (GPU) executed programs configured to be executed on a first GPU having a first application binary interface (ABI), the method comprising:

• providing a second GPU having a second ABI different from the first ABI of the first GPU;
• executing an application program that utilizes a plurality of GPU-executed programs configured to be executed for the first ABI of the first GPU;
• executing a run-time executable cross-compiler including, while the application program is executing, emulating the first ABI using hardware resources of the second GPU by translating between the first ABI and the second ABI;
• and
• executing the plurality of GPU-executed programs on the second GPU with the emulated first ABI, and passing output of the plurality of GPU-executed programs for the emulated first ABI through the second ABI.

A computing device for just-in-time cross-compiling compiled binaries of application programs that utilize graphics processing unit (GPU) executed programs configured to be executed on a first GPU having a first application binary interface (ABI), the computing device comprising:

• a second GPU having a second ABI different from the first ABI of the first GPU;
• and
• a processor configured to:
• execute an application program that utilizes a plurality of GPU-executed programs configured to be executed for the first ABI of the first GPU;
• and
• execute a run-time executable cross-compiler configured to, while the application program is being executed:
• iterate through instructions of each of the plurality of GPU-executed programs to gather summary data selected from the group consisting of register usage data, memory access pattern data, and implicit control flow graph data;
• allocate registers of the second GPU to emulate registers of the first GPU including first ABI input register locations and first ABI output register locations, based on the summary data;
• and
• emulate the first ABI using the emulated registers and translating between the first ABI and the second ABI;
• wherein the second GPU is configured to;
• execute the plurality of GPU-executed programs on the second GPU with the emulated first ABI, and pass output of the plurality of GPU-executed programs for the emulated first ABI through the second ABI.
