Subject: Add tuple struct constructor to value namespace
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4c40ba4bb28b83061f3963f806d26f0599497f93;p=thirdparty%2Fgcc.git

Add tuple struct constructor to value namespace

A tuple struct constructor should be inserted in the value namespace
during name resolution in order to reject multiple definitions of the
function.

gcc/rust/ChangeLog:

	* resolve/rust-toplevel-name-resolver-2.0.cc (TopLevel::visit): Add
	the struct constructor to the value namespace.

gcc/testsuite/ChangeLog:

	* rust/compile/name_resolution22.rs: New test.
