Arnaud Robin authored
On desktop systems, we use a very basic tiering strategy: Everything is initially compiled with Liftoff, and once that is done, the module can start being used. Concurrently to the execution, we re-compile all code with TurboFan, and hot-swap each function once TurboFan finishes. We should start using a more dynamic strategy where each function is tiered-up when judged necessary. This change will then tier-up each liftoff function once it has been called 5 times. I then added a counter in the native module, that is updated directly from Liftoff code, and a runtime call is then made when the counter reaches the goal.

Jakob Gruber authored
With work on NCI proceeding, it makes sense to test multiple pipeline configurations. The nci variant (passes --turbo-nci) now spawns dedicated NCI compilation jobs and inserts generated code into the code cache. The nci_as_highest_tier variant (passes --turbo-nci-as-highest-tier) simply replaces TF with NCI code (no extra jobs, no extra caching). This mode stresses NCI generated code more than the nci variant, in which NCI code only runs on cache hits.

This regression is due to miscalculating the mapped_count in escape-analysis-reducer. Since NewArguemntsElements contains the entire arguments count instead of the rest argument size, we need to subtract (or add in the case of the reversed arguments stack) the formal parameter count to the index.

Split the capacity calculation logic and the allocation logic for StringTable resizing (both shrinking and enlarging). This allows us to: a) Precalculate the new size, without potentially first shrinking then resizing again, b) Make the final size calculation more explicit, b) In the future, maybe allow the allocation to happen outside a lock, and the rehashing to be inside it, for a concurrent string table.
