We needed to manually added the `DW_OP_deref` ourselves in earlier LLVM, but starting with [D31439] in LLVM 5, it appears that LLVM will always handle this itself. When we were still adding this manually, the resulting `.debug_loc` had too many derefs, and this failed test `debuginfo/by-value-self-argument-in-trait-impl.rs`. [D31439]: https://reviews.llvm.org/D31439 Fixes rust-lang#47611. cc @alexcrichton r? @michaelwoerister

Ah I think @michaelwoerister is on leave for a bit, so given the fact that this should pass tests before/after LLVM updates I'm going to r+. If this is in error though I'm sure we can find another solution that also passes all the tests everywhere! @bors: r+ |
