Subject: Fix missing error on duplicated nodes
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=76131dd1d561bdc2064e9f91ed19c275d09e7166;p=thirdparty%2Fgcc.git

Fix missing error on duplicated nodes

When we tried to insert a shadowable node and another shadowable node has
been inserted before, we didn't emit any error if the node has already
been inserted previously and failed silently.

gcc/rust/ChangeLog:

	* resolve/rust-rib.cc (Rib::insert): Emit an error when trying to
	insert an already inserted node.
