Nico Hartmann f4b98cc654 Revert "[turbofan] Improve equality on NumberOrOddball" ... This reverts commit 6204768bab. Reason for revert: A number of Clusterfuzz reports (e.g. https://bugs.chromium.org/p/chromium/issues/detail?id=1079474) Original change's description: > [turbofan] Improve equality on NumberOrOddball > > This CL cleans up CompareOperationFeedback by replacing it with a > composable set of flags. The interpreter is changed to collect > more specific feedback for abstract equality, especially if oddballs > are involved. > > TurboFan is changed to construct SpeculativeNumberEqual operator > instead of the generic JSEqual in many more cases. This change has > shown a local speedup of a factor of 3-10, because the specific > operator is way faster than calling into the generic builtin, but > it also enables additional optimizations, further improving > runtime performance. > > Bug: v8:5660 > Change-Id: I856752caa707e9a4f742c6e7a9c75552fb431d28 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2162854 > Reviewed-by: Mythri Alle <mythria@chromium.org> > Reviewed-by: Georg Neis <neis@chromium.org> > Commit-Queue: Nico Hartmann <nicohartmann@chromium.org> > Cr-Commit-Position: refs/heads/master@{#67645} TBR=rmcilroy@chromium.org,neis@chromium.org,mythria@chromium.org,nicohartmann@chromium.org Change-Id: I3410310ed2b1ff2eaee70c1b91c3151d35866108 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: v8:5660 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2190414 Reviewed-by: Nico Hartmann <nicohartmann@chromium.org> Commit-Queue: Nico Hartmann <nicohartmann@chromium.org> Cr-Commit-Position: refs/heads/master@{#67673}		2020-05-08 09:16:11 +00:00
