I need know what DERIVED_FROM_P do and How use this...
What part of the comment: /* Nonzero iff TYPE is derived from PARENT. Ignores accessibility and ambiguity issues. */ #define DERIVED_FROM_P(PARENT, TYPE) \was unclear? If you didn't read that comment, you'll want to examine the various files in doc/*.texi for documentation, as well as the definitions themselves.
Is there any source code sample?
Yes, please see the gcc source code.
