This is a temporary hack. There are two closely related bugs in methodWriteBarrier. One: the two signatures are meant to be essentially the same, but they aren't; the slot-based signature fails to do thrash detection in a common case. Two: if thrash detection were always done, it would unbrand the global object, wrecking our SunSpider score. Both bugs are tracked in bug 630354. The bugs have been precariously balanced against one another for a while. I accidentally changed the status quo in rev b90090c29571, causing a 15% SS regression. This patch changes it back. --HG-- extra : rebase_source : d2e4605599b633b968277b7f5c1a4fba7218d7d7 |

An explanation of the Mozilla Source Code Directory Structure and links to
project pages with documentation can be found at:
https://developer.mozilla.org/en/Mozilla_Source_Code_Directory_Structure
For information on how to build Mozilla from the source code, see:
http://developer.mozilla.org/en/docs/Build_Documentation
To have your bug fix / feature added to Mozilla, you should create a patch and
submit it to Bugzilla (https://bugzilla.mozilla.org). Instructions are at:
http://developer.mozilla.org/en/docs/Creating_a_patch
http://developer.mozilla.org/en/docs/Getting_your_patch_in_the_tree
If you have a question about developing Mozilla, and can't find the solution
on http://developer.mozilla.org, you can try asking your question in a
mozilla.* Usenet group, or on IRC at irc.mozilla.org. [The Mozilla news groups
are accessible on Google Groups, or news.mozilla.org with a NNTP reader.]
You can download nightly development builds from the Mozilla FTP server.
Keep in mind that nightly builds, which are used by Mozilla developers for
testing, may be buggy. Firefox nightlies, for example, can be found at:
