Jakob Gruber 9145388055 Reland "[osr] Use the new OSR cache" ... This is a reland of commit 91da38831d Fixed: Use an X register for JumpIfCodeTIsMarkedForDeoptimization on arm64. Original change's description: > [osr] Use the new OSR cache > > This CL switches over our OSR system to be based on the feedback > vector osr caches. > > - OSRing to Sparkplug is fully separated from OSR urgency. If > SP code exists, we simply jump to it, no need to maintain an > installation request. > - Each JumpLoop checks its dedicated FeedbackVector cache slot. > If a valid target code object exists, we enter it *without* > calling into runtime to fetch the code object. > - Finally, OSR urgency still remains as the heuristic for > requesting Turbofan OSR compile jobs. Note it no longer has a > double purpose of being a generic untargeted installation > request. > > With the new system in place, we can remove now-unnecessary > hacks: > > - Early OSR tierup is replaced by the standard OSR system. Any > present OSR code is automatically entered. > - The synchronous OSR compilation fallback is removed. With > precise installation (= per-JumpLoop-bytecode) we no longer > have the problem of 'getting unlucky' with JumpLoop/cache entry > mismatches. Execution has moved on while compiling? Simply spawn > a new concurrent compile job. > - Remove the synchronous (non-OSR) Turbofan compile request now > that we always enter available OSR code as early as possible. > - Tiering into Sparkplug no longer messes with OSR state. > > Bug: v8:12161 > Change-Id: I0a85e53d363504b7dac174dbaf69c03c35e66700 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3596167 > Commit-Queue: Jakob Linke <jgruber@chromium.org> > Auto-Submit: Jakob Linke <jgruber@chromium.org> > Reviewed-by: Leszek Swirski <leszeks@chromium.org> > Commit-Queue: Leszek Swirski <leszeks@chromium.org> > Cr-Commit-Position: refs/heads/main@{#80147} Bug: v8:12161 Change-Id: Ib3597cf1d99cdb5d0f2c5ac18e311914f376231d Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3606232 Auto-Submit: Jakob Linke <jgruber@chromium.org> Reviewed-by: Leszek Swirski <leszeks@chromium.org> Commit-Queue: Leszek Swirski <leszeks@chromium.org> Cr-Commit-Position: refs/heads/main@{#80167}		2022-04-26 07:26:52 +00:00
