This reverts commit e3ccb538. Reason for revert: Speculative revert for ARM 64 CFI fails - https://ci.chromium.org/p/v8/builders/ci/V8%20Linux%20-%20arm64%20-%20sim%20-%20CFI/5174? Original change's description: > Reland "[sparkplug][deoptimizer] Deoptimize to baseline." > > This is a reland of bdcd7d79 > > Handle lazy deopts when the current bytecode is JumpLoop. > Instead of advancing to the next bytecode, re-execute the JumpLoop. > > TBR=jgruber@chromium.org, neis@chromium.org > > Original change's description: > > [sparkplug][deoptimizer] Deoptimize to baseline. > > > > If we have baseline code, deoptimize to baseline instead of the > > interpreter. The process is similar to deopting to the interpreter. > > We just use different builtins > > (BaselineEnterAtBytecode/BaselineEnterAtNextBytecode) instead of > > InterpreterEnterBytecodeDispatch/InterpreterEnterBytecodeAdvance, that > > patch an interpreter frame to a baseline frame and continue execution in > > baseline code (based on the deopt type, at the current or next > > bytecode). > > > > Bug: v8:11420 > > Change-Id: Iabaefb36c05155a435c7b380906a86d9b9d549fa > > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2695591 > > Commit-Queue: Patrick Thier <pthier@chromium.org> > > Reviewed-by: Leszek Swirski <leszeks@chromium.org> > > Reviewed-by: Georg Neis <neis@chromium.org> > > Reviewed-by: Jakob Gruber <jgruber@chromium.org> > > Cr-Commit-Position: refs/heads/master@{#73609} > > Bug: v8:11420 > Change-Id: Ib8cac028121188ddc23ff29377760ed684eb7392 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2783035 > Reviewed-by: Patrick Thier <pthier@chromium.org> > Reviewed-by: Leszek Swirski <leszeks@chromium.org> > Commit-Queue: Patrick Thier <pthier@chromium.org> > Cr-Commit-Position: refs/heads/master@{#73636} Bug: v8:11420 Change-Id: Icd797b4979a114a2a627e12c8bb7d2215df03182 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2785074Reviewed-by: Deepti Gandluri <gdeepti@chromium.org> Reviewed-by: Bill Budge <bbudge@chromium.org> Commit-Queue: Deepti Gandluri <gdeepti@chromium.org> Cr-Commit-Position: refs/heads/master@{#73643}
