In ES2016, function declarations nested in blocks are formally allowed. This was never a part of ECMAScript, but was a common extension. Unfortunately implementations differed in the exact semantics. Annex B.3.3 in the spec tries to standardize the parts which are common to different implementations, but does so with some fairly complicated semantics. This CL addresses three issues related to annex B.3.3: * When the outer function had a complex parameter list, no hoisting whatsoever was being performed. * Hoisting was not blocked by parameters of the same name. * Hoisting was not blocked by nested lexical declarations of the same name. We had tests which checked for the second, but they were incorrectly passing due to the first. This CL adds more complete tests.

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.
