This commit won't be quite as useful until I implement RUST_PATH and
until we change `extern mod` to take a general string instead of
an identifier (#5682 and #6407).
With that said, now if you're using rustpkg and a program contains:
extern mod foo;
rustpkg will attempt to search for `foo`, so that you don't have to
provide a -L directory explicitly. In addition, rustpkg will
actually try to build and install `foo`, unless it's already
installed (specifically, I tested that `extern mod extra;` would
not cause it to try to find source for `extra` and compile it
again).
This is as per #5681.
Incidentally, I changed some driver code to infer the link name
from the crate link_meta attributes. If that change isn't ok, say
something. Also, I changed the addl_lib_search_paths field in the
session options to be an @mut ~[Path] so that it can be modified
after expansion but before later phases.
Add new private hashmap function
fn mangle(&mut self,
k: K,
not_found: &fn(&K) -> V,
found: &fn(&K, &mut V)) -> uint
Rewrite find_or_insert() and find_or_insert_with() on top of mangle().
Also take the opportunity to change the return type of find_or_insert()
and find_or_insert_with() to &'a mut V. This fixes#6394.
The `callee_id` in `ast::expr` in only used in a couple expression variants. This moves the `callee_id` into those branches to make it more clear when its should be used.
Also, it fixes a bug in a std::run test when there is a symlink in the path rust where was checked out.
This fixes#6745, which itself relates to #4202. Slightly ham-fisted -- feel particularly funny about using the typeck phase to gather the base -> impl mapping, and the separate code paths for traits vs. "real" bases feels like it could be avoided -- but it seems to work.
As always, open to suggestions if there's a better way to accomplish what I'm trying to do.
@catamorphism r?
This is a better pipeline, both faster-running and produces faster code.
For some reason the `mergefunc` pass screws over resolve. I have no idea why though.
Closes#5090 by using the excellent new generic deriving code
Promotes the unreachable code attribute to a lint attribute (instead of always being a warning)
Fixes some edge cases when creating hashmaps/hashsets and also when consuming them. (fixes#5998)
