OpenMP’s static worksharing dispatch builtins now accept loop parameters such as iteration count, start, step, and chunk size. This information is passed to the OMPT dispatch callback, providing crucial details about the loop for runtime analysis and debugging. The change involves updating builtin definitions and expansion logic across GCC and libgomp.
