Bug ID: 23624
Summary: xfail traits.exp with older llvm
Product: gdb
Version: 8.2
Status: NEW
Severity: normal
Priority: P2
Component: rust
Assignee: unassigned at sourceware dot org
Reporter: tromey at sourceware dot org
Target Milestone: ---

I've wasted time looking into traits.exp failures a couple of times,
only to find out that I was using a rustc built against LLVM 5 --
before the needed infrastructure landed.

The llvm version can be detected using "rustc -vV".
Then these tests can be xfailed.

There are some enum tests that should also be xfail'd; but before
this can be done, we need a release of rustc that has the enum
fixes. See https://github.com/rust-lang/rust/pull/54004

... and when the enum xfails are done, some test output can also
be tightened up a bit; see bug 23626.
