vporpo	c7053ac202	[SandboxVec][BottomUpVec] Disable crossing BBs (#124039) ... Crossing BBs is not currently supported by the structures of the vectorizer. This patch fixes instances where this was happening, including: - a walk of use-def operands that updates the UnscheduledSuccs counter, - the dead instruction removal is now done per BB, - the scheduler, which will reject bundles that cross BBs.	2025-01-23 15:08:13 -08:00

vporpo	f7ef7b2ff7	[SandboxVec][Scheduler] Implement rescheduling (#115220) ... This patch adds support for re-scheduling already scheduled instructions. For now this will clear and rebuild the DAG, and will reschedule the code using the new DAG.	2024-11-06 20:59:49 -08:00
vporpo	1d09925b4a	[SandboxVec][Scheduler] Boilerplate and initial implementation. (#112449) ... This patch implements a ready-list-based scheduler that operates on DependencyGraph. It is used by the sandbox vectorizer to test the legality of vectorizing a group of instrs. SchedBundle is a helper container, containing all DGNodes that correspond to the instructions that we are attempting to schedule with trySchedule(Instrs).	2024-10-18 16:18:43 -07:00
