Hi,

It might be of interest to have a builtin to convert a type name to a string.
Given a type or a variable, the builtin would return the type of it as a
string.
It could be used to build debug messages:


#define ASSERT_NULL(p) do { \
 if ((p) == NULL)           \
    printf("%s * %s == NULL\n", __builtin_typestringof(*p), #p); \
} while(0);

Regards.
