Reason for revert: Did not fail on another roll including this CL .. Original issue's description: > Revert of [compiler] Make feedback vector cope with flag changes. (patchset #1 id:1 of https://codereview.chromium.org/1869693003/ ) > > Reason for revert: > Blocks current roll: https://codereview.chromium.org/1876713002/ according to bisect: https://codereview.chromium.org/1872353002/#ps80001 > > Original issue's description: > > [compiler] Make feedback vector cope with flag changes. > > > > This fixes corner cases where the layout of feedback vectors baked into > > the snapshot is different from the expected layout, depending on some > > runtime flags. We make sure the feedback vector is regenereated for > > functions that are not compiled. Flag changes of this kind are only > > allowed when code is not serialized. > > > > An alternative solution would be to not serialize the feedback vector > > for such cases in the first place. That solution however would have a > > higher overhead, as it would required the serializer to be able to > > recognize feedback vectors while generating a snapshot. > > > > R=mvstanton@chromium.org > > TEST=mjsunit/regress/regress-crbug-600995 > > BUG=chromium:600995 > > LOG=n > > > > Committed: https://crrev.com/460bff5fb6af2bd79e610f89afdf6da9dba3cf0c > > Cr-Commit-Position: refs/heads/master@{#35339} > > TBR=mvstanton@chromium.org,mstarzinger@chromium.org > > BUG=chromium:600995 > LOG=N > NOTRY=true > > Committed: https://crrev.com/78049e9c4837f053575d6c71e53ae12fec99f1aa > Cr-Commit-Position: refs/heads/master@{#35392} TBR=mvstanton@chromium.org,mstarzinger@chromium.org # Skipping CQ checks because original CL landed less than 1 days ago.
