From 2ecce7ccc5d74eb3d6b0ff400b2a19944e2ae51a Mon Sep 17 00:00:00 2001 From: David Wood Date: Thu, 11 Oct 2018 19:36:51 +0200 Subject: Extend lang items to assert correct target. This commit extends the existing lang items functionality to assert that the `#[lang_item]` attribute is only found on the appropriate item for any given lang item. That is, language items representing traits must only ever have their corresponding attribute placed on a trait, for example. --- .../ui/panic-handler/panic-handler-wrong-location.rs | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) create mode 100644 src/test/ui/panic-handler/panic-handler-wrong-location.rs (limited to 'src/test/ui/panic-handler/panic-handler-wrong-location.rs') diff --git a/src/test/ui/panic-handler/panic-handler-wrong-location.rs b/src/test/ui/panic-handler/panic-handler-wrong-location.rs new file mode 100644 index 00000000000..04e02682bc1 --- /dev/null +++ b/src/test/ui/panic-handler/panic-handler-wrong-location.rs @@ -0,0 +1,18 @@ +// Copyright 2018 The Rust Project Developers.
