626706 - Add hardcore checking option, to add to nightly testing

Status: RESOLVED DUPLICATE of bug 624094

(Core :: JavaScript Engine, defect)

Description

[Paul Biggar]

There are a number of patches lying around which find bugs in spidermonkey, and which we'd like to use to prevent regressions, but which can't really effectively be added right now.

For example, bug 624094 would be great to add to constantly detect OOMs, but the code it adds is unsuitable for DEBUG builds. njn has a similar bug with the same characteristics.

So we'd like to add a --enable-hardcore-checking flag, wrap the code in that, and add it to automated testing. We're getting automated builds with various flags in bug 609413, so we'll add this to that, and then get warnings when we regress.

Bug 529430.  But come to think of it, I was partway through a version of it that could be turned on entirely via runtime flags (as opposed to compile-time flags), so it wouldn't necessarily need a special build

dvander showed interest a while back in having a similar "stress" mode for JM.

I thought this would need a configuration option, but it went in as a shell flag in debug mode, so we don't need this anymore.
