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.

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).

Blink already has code for handling invalid cached data. The attached test
ensures that cached data is gracefully rejected if it cannot be used.
This also unifies parser cache and code cache handling.

These methods for used for compressed libraries, where GetSource* functions
contained the compressed sources and [GS]etRawSource* the uncompressed
sources. This is dead code since the API no longer supports compression.
(If you need/want compressed sources, use the external startup data and
compress/uncompress on the Embedder's side.)

If we hade }` the right brace was always treated as part of the
template literal. We should only treat the right brace as part of
the literal when we continue to parse the template literal after a

This adds a common perf configuration for JSTests including
Classes, Collections, Iterators and Strings. This allows
the android test runner to handle subdirectories correctly
and to share the base.js resource in the parent directory.
The new json config has added resources configs for the
Android runner.
The perf runner's relative paths on the device are fixed as
well. Resources are only pushed on the configuration node
where they are specified. They are pushed to a dir on the
device that follows the same directory structure as on the
host. The binary is executed in the benchmark folder on the
device like on the host to allow relative path file
loading.
