Change build_reduced_graph.rs so the fields def and module of NsDef are never both Some unless the NsDef represents a duplicate definition (see issue 26421).
This should get `--libdir` working as well as it was a couple of weeks ago. (That is, it still rewrites paths incorrectly but it no longer fails during `make install`.)
Fixesgentoo/gentoo-rust#28 and gentoo/gentoo-rust#29.
insert() returns bool, but it was wrongly stated that if the set had the
key already present, that key would be returned (this was probably
copied from the HashMap docs). Also remove a reference to the
module-level documentation, which doesn't make sense as it doesn't give
any more context.
This is to handle the case where CFG_LIBDIR is not a direct child of
CFG_PREFIX (in other words, where CFG_LIBDIR_RELATIVE has more than
one component).
Define a newtype `NameBinding` for `Rc<RefCell<Option<NsDef>>>` and refactor `NameBindings` to be a `NameBinding` for each namespace.
Replace uses of `NameBindings` with `NameBinding` where only one binding is being used (in `NamespaceResult`, `Target,` etc).
Refactor away `resolve_definition_of_name_in_module` and `NameDefinition`.
f357d55 caused a regression by retrieving item names from metadata, while previously using the last element of its absolute path (which in the case of a root module is the prefixed crate name since the stored path in metadata is empty)
fixes#28927
Another rustfmt PR.
I ran rustfmt, then split the changes in multiple commits. First commit are the non-problematic changed. The others are all the little weirdness that caught my attention and could be discussed.
These really aren't documented well at all. The fact that doc comments end on a `*/` is really weird. I'm not sure if this is a mistake or not though.
None of the block comments are even mentioned in the [book nightly](http://doc.rust-lang.org/nightly/book/comments.html). Probably should be fixed.
The first commit fixes the "jobserver unavailable" warning reported at gentoo/gentoo-rust#29. I don't think the warning is related to the compilation failure shown there.
The remaining commits are minor fixes I noticed while investigating the jobserver warning.
Simplify HIR folder so that it only maps 1 item to 1 item, removing a bunch of asserts. This is a small refactoring on the way to my larger branch for moving items out of line in the tree and isolating attempts to access them.
r? @nrc
The example given for the manual implementation of the core::fmt::Debug trait doesn't match the output after the code sample. This updates it so it matches.
