[V8] Report v8::AfterCompile and v8::CompileError to listener on pause · affe4c03

kozyatinskiy authored Dec 11, 2014

V8 didn't report compile events on pause before this patch. These events can be important for listener. For example, DevTools allows user to execute some JS code on pause and needs to show correct stack trace in message from it.

adamk authored Dec 10, 2014

This completes the first round of optimizations for Map and Set.
All non-key-dependent methods now have a Hydrogen version, and
for keyed methods, string versions are optimized.

Optimize Object.seal and Object.preventExtensions · 4fa7ae1c

adamk authored Dec 10, 2014

They both now run fast (due to utilizing transitions instead of always
creating new maps) and sealed or non-extensible objects can stay in
fast mode after transitioning.

This almost entirely reuses the code for transitioning objects
frozen by Object.freeze(), with the added benefit of freeing
up a bit on the map (we no longer keep track of frozen-ness,
as that bit wasn't used for anything interesting).
