Subject: c++: Don't add enums to class's decl_list
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6e1e0decc9e17a4283d1b5508e892be5215b8ab9;p=gcc.git

c++: Don't add enums to class's decl_list

We don't need to add CONST_DECLs to a template decl's decl list.  Also made the
code flow a bit clearer.

	gcc/cp/
	* class.c (maybe_add_class_template_decl_list): Don't add CONST_DECLs.
