Simplify synthetic roots creation in heap snapshot · 269c46ee

yurys@chromium.org authored Sep 22, 2014

The synthetic roots exist in every snapshot and there are no actual objects corresponding to them (there was attempt to create some virtual objects to reuse existing snapshot builder but it just complicated the things).

Previously synthetic root wouldn't have been added if it was empty. Current implementation always adds all synthetic roots in the snapshot no matter if they are empty or not.

Further improve deopt reason output. · 73844675

svenpanne@chromium.org authored Sep 22, 2014

* Make the detailed deopt reason mandatory on x64, other platforms
  will follow in separate CLs.

* Extracted and improved jump table entry sharing logic: When
  --trace-deopt is on, we get separate entries for different deopt
  reasons. This enables us to distinguish the several reasons single
  instructions can have.

* Don't emit superfluous jump table comments: The bailout ID is still
  visible, and the jump table entry number is not interesting (but
  easy to determine if really needed).

* Unify the internal name of the jump table member across platforms.
