I wanted to run the gdb.rust tests against older versions of the Rust compiler, to ensure that changes I am making don't break debugging when using older compilers. However, this did not work because simple.rs now uses unchecked unions, which were only added in Rust 1.19. This patch splits the union code into its own file, so that simple.exp can continue to work. I tested this with selected rust versions back to 1.12. gdb/testsuite/ChangeLog 2020-04-01 Tom Tromey <tromey@adacore.com> * gdb.rust/union.rs: New file. * gdb.rust/union.exp: New file. * gdb.rust/simple.rs (Union, Union2): Move to union.rs. (main): Update. * gdb.rust/simple.exp: Move union tests to union.exp.
