Would this cause any extra > conversions? uchar -> char in this case? It's specific to how builtin_astype works. It drops first argument type and only cares about matching first argument size with the data type size provided as a second argument. So basically with single line we get all possible and impossible overloads of as_char(*). This define will pass any variable type char,uchar to builtin_astype. https://reviews.llvm.org/D28136 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
