Register Pressure Sensitivity in the GCC Middle End

Explore register pressure sensitivity in the gcc middle end during this 44-minute Birds of a Feather (BoF) session from the Linux Plumbers Conference. Delve into topics such as the ssaliveVet allocator, propagation paths, global register locator, and gimbal or expand timing. Examine experiments, compiler pressure register classes, approximation techniques, and register dependency. Investigate pressure classes, regions, remoterization, and scheduling. Learn about instructor selection, modular scheduling tools, and special motion descriptions. Discover insights on AI in gcc, the Postmile project, compiler field constraints, and the Pearl Bench request.
