Bug 1632672 - Optimize OOB accesses with int32 index better for typed arrays. r?anba!
48 bytes, text/x-phabricator-request
Details | Review

Since bug 1129202 we can optimize double OOB TypedArray access, but not int32. That seems like a potential performance problem. We also need this for the Warp transpiler.

Without type monitoring we can more easily support this now.
