That's a good idea, but I'm not really familiar enough with the structure of clang to be sure I'm not doing it in a ham-fisted way. Can you clarify? Are you suggesting adding something like ASTContext::isPointeeTypeCharSize() and ASTContext::isIntegerTypePointerSize()? Or maybe a single specialized function somewhere that does both checks like ASTContext::areOperandNullPointerArithmeticCompatible()? https://reviews.llvm.org/D37042 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
