Codesearch seems to be a few days out of date (at least within v8).

For example, the following page:

https://cs.chromium.org/chromium/src/v8/test/js-perf-test/SixSpeed.json

Click 'History':

The latest patch that shows on this page is 2db0e8cbcf93bdcbf77d7a7a1e7d461e8d6fce5f

Actually there have been 3 patches since then that should show:

Another example is
https://cs.chromium.org/chromium/src/v8/src/compiler/js-call-reducer.cc

Which should show: 994d906ec3b3479ba1b9a0ebd23c9efcbea6806f (3 days ago)

but has 9121f72a91a5e5dab6477ddf4806ff849f6714eb as the latest.
