Sorry, I misread your question as 'if the enum can be represented in 2 bits'. You're right, the check can be skipped if the _bitfield_ is 2 bits wide. I think this can be handled along with the 1-bit unsigned BOOL case in a follow up. https://reviews.llvm.org/D30423 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
