Hello, I am in the process of writing a plugin that parses the header files of a C library using GCC, walks the AST in GENERIC format, and translates to C code for a foreign function interface (for LuaJIT).
Many libraries internally use different C type names than those part of the API, using the C preprocessor for name mangling. I would like to rename certain tree nodes back to their known API name, before generating the C output code. How does one reassign the IDENTIFIER_POINTER of an IDENTIFIER_NODE? How is the memory of the identifier string allocated and freed? I have looked at build_string() in tree.c, but this function seems to apply only to STRING_CST nodes. There are also the functions make_node_stat() and build*_stat(), but I cannot find any call to these functions with tree code IDENTIFIER_NODE. I would be thankful for any pointers. Peter
