The ES2016 draft spec defines a sort of fast path for constructing a TypedArray based on another TypedArray. This patch implements that alternative path in TypedArray construction. It is verified by test262 tests, which now pass. This patch also has a slight cleanup of TypedArray code by using a macro for TypedArray type checks, as is done for other types. This patch includes a minor spec violation: In the same-type case, the spec indicates that the underlying ArrayBuffer should be copied until the end, and this is fixed up by making the [[ArrayLength]] shorter. This is observable with the buffer getter. This patch just copies the used part of the underlying ArrayBuffer.

This directory contains code for binding the test262 test suite into the v8 test harness. The tests are checked out as a dependency from https://chromium.googlesource.com/external/github.com/tc39/test262 at a revision specified in the DEPS file as 'data' in this directory. They are fetched with 'gclient sync'. To update to a newer version, please change the DEPS file. Using a newer version, e.g. 'deadbeef' may be possible but the tests are only known to pass (and indeed run) with the DEPS revision. Example: cd data git fetch git checkout deadbeef If you do update to a newer revision you may have to change the test harness adapter code since it uses internal functionality from the harness that comes bundled with the tests. You will most likely also have to update the test expectation file.
