Multi-version shaders

A computing device configured to generate a stitched shader program, the computing device comprising:

• a memory;
• and
• a processor configured to execute a linker, the linker configured to:
• identify a set of shader programs to include in the stitched shader program, wherein the set of shader programs includes at least one multiversion shader program that includes a first version of instructions and a second version of instructions, wherein the first version of instructions uses a first number of resources that is different than a second number of resources used by the second version of instructions;
• combine the set of shader programs to form the stitched shader program, wherein the stitched shader program includes instructions corresponding to the multiversion shader program;
• determine a number of resources for the stitched shader program;
• and
• based on the determined number of resources, modify the instructions corresponding to the at least one multiversion shader program to execute either the first version of instructions, or the second version of instructions, when the at least one multiversion shader is executed.

A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to generate a stitched shader program, by:

• identifying a set of shader programs to include in the stitched shader program, wherein the set of shader programs includes at least one multiversion shader program that includes a first version of instructions and a second version of instructions, wherein the first version of instructions uses a first number of resources that is different than a second number of resources used by the second version of instructions;
• combining the set of shader programs to form the stitched shader program, wherein the stitched shader program includes instructions corresponding to the multiversion shader program;
• determining a number of resources for the stitched shader program;
• and
• based on the determined number of resources, modifying the instructions corresponding to the at least one multiversion shader program to execute either the first version of instructions, or the second version of instructions, when the at least one multiversion shader is executed.
