Subject: c++: Add lang_decl, type_decl API
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0fc6469d2491bb588d02c5416b5be0131aa4c3b0;p=gcc.git

c++: Add lang_decl, type_decl API

We need to call the lang_decl and type_decl creators from the module
loading machinery.  This makes them reachable.

	gcc/cp/
	* cp-tree.h (maybe_add_lang_decl_raw, maybe_add_lang_type_raw):
	Declare.
	* lex.c (maybe_add_lang_decl_raw, maybe_add_lang_type_raw):
	Externalize, reformat.
