Subject: gccrs: Add regression test for invalid label name
X-Git-Tag: basepoints/gcc-15~1994
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=119e0be8b6eea63a95c89d449c38aa133e6ad5ab;p=thirdparty%2Fgcc.git

gccrs: Add regression test for invalid label name

An error message should be emitted when the rust code contains invalid
label name. Add a new test for this behavior.

gcc/testsuite/ChangeLog:

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