Revert of Use ES2015-style TypedArray prototype chain (patchset #5 id:80001 of https://codereview.chromium.org/1541233002/ ) Reason for revert: [Sheriff] Changes layout tests. Please fix upstream first if intended. https://build.chromium.org/p/client.v8.fyi/builders/V8-Blink%20Linux%2064/builds/3689 Original issue's description: > Use ES2015-style TypedArray prototype chain > > This patch switches TypedArrays to use the prototype chain described > in the ES2015 specification, which adds a %TypedArray% superclass above > all individual TypedArray types. Most methods are defined on the > superclass rather than the subclasses. > > In order to prevent a performance regression, a few methods are > marked as inline. Inlining might prevent code which was previously > monomorphic from becoming polymorphic, and it was specifically > applied in places where methods became more polymorphic than before. > Tests with realistic workloads would be nice to do before this > ships in stable. > > This patch does not bring TypedArrays up to full spec compliance. In > particular, @@species is not yet supported. > > R=cbruni > BUG=v8:4085 > LOG=Y > > Committed: https://crrev.com/07c91dccbe55c7be3ec75857dee5ad59873330b7 > Cr-Commit-Position: refs/heads/master@{#33050} TBR=caitpotter88@gmail.com,cbruni@chromium.org,littledan@chromium.org NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true BUG=v8:4085 Review URL: https://codereview.chromium.org/1554523002 Cr-Commit-Position: refs/heads/master@{#33053}
