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

[Christian Wailes]

Howdy everyone.

My new analysis introduces annotations that are placed on class methods.
I'd like a way to check types, as my analysis encounters variable
declarations, to see if they have members marked with my annotations.  I
could iterate over all of the methods for record types to check for my
annotations, but this seems expensive.  The best way I can think of to
accomplish this is to add a bool value to the CXXRecordDecl bitfield.  I
have two questions for the list: a) can anyone think of a better way to do
this? and b) is there any objection to adding another bit to the field?  If
my count is correct there are currently 59 bits in the field.
