Subject: (duplicate_decls): Set DECL_INLINE in newdecl so it is copied into olddecl.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=850cba2976f2d33587954adae6590006289be618;p=gcc.git

(duplicate_decls): Set DECL_INLINE in newdecl so it is copied into olddecl.

Don't set DECL_EXTERNAL in olddecl.
Preserve DECL_UID of olddecl.
