Make conflicting borrow description more robust. This commit improves the logic for place descriptions in conflicting borrow errors so that borrows of union fields have better messages even when the unions are embedded in other unions or structs.
2019-01-04 19:56:41 +00:00
error[E0502]: cannot borrow `r.r2_union.f3_union` (via `r.r2_union.f3_union.s2_leaf.l1_u8`) as immutable because it is also borrowed as mutable (via `r.r2_union.f3_union.s1_leaf.l1_u8`)
Remove redundant `ignore-tidy-linelength` annotations This is step 2 towards fixing #77548. In the codegen and codegen-units test suites, the `//` comment markers were kept in order not to affect any source locations. This is because these tests cannot be automatically `--bless`ed.

Improve diagnostic labels and add note. This commit improves diagnostic labels to mention which field a borrow overlaps with and adds a note explaining that the fields overlap.
