[cfe-dev] Using a Bit in the CXXRecordDecl Bitfield

[Christian Wailes]

Would there be any objection to me adding a data member to the
sema::AnalysisBasedWarnings class instead?  It would be used to cache some
information and speed up the analysis.

And yes, we would like this to eventually be merged into trunk.
