I also renumbered things at the same time; ``in`` was shifted into its
alphabetical position and the reserved keywords were reordered (a couple
of them were out of order).
Previously, if you wanted to bind a field mutably or by ref, you had to
do something like Foo { x: ref mut x }. You can now just do
Foo { ref mut x }.

This bug showed up because the visitor only visited the path of the implemented
trait via walk_path (with no corresponding visit_path function). I have modified
the visitor to use visit_path (which is now overridable), and the privacy
visitor overrides this function and now properly checks for the privacy of all
paths.

Specifically, we can now use:
+ beginning-of-defun
+ end-of-defun
+ mark-defun
where "defun" means a Rust item.
+ Add tests in rust-mode-tests.el
+ Fix indentation in rust-mode-tests.el
+ Add support for trait to Imenu
- Removed the `log` keyword;
- Removed keyword duplicates;
- Highlighted `const` as `Error` rather than `StorageClass`; and
- Highlighted all the reserved keywords as `Error` rather than as
`Keyword`.
(As usual, these highlightings can be overridden if desired.)
This fixes a regression introduced in #10793.
Having a colorscheme which highlights Float the same as Number (I
believe most do), I hadn't noticed that having the special case of "5."
floats (which was one of the added features in #10793) last made it take
precedence, and so it was left to @thestinger to notice it.
The regression meant that in `5.0`, the `5.` was a `rustFloat` (linked
by default to `Float`) and the `0` was a `rustDecNumber` (linked by
default to `Number`), and for `5.0f32` the `5.` was a `rustFloat` and
the `0f32` was a second `rustFloat` (and thus appeared correctly, though
for the wrong reason).
The first commit was approved from another pull request, but I wanted to rebase LTO on top of it.
LTO is not turned on by default at all, and it's hidden behind a `-Z` flag. I have added a few small tests for it, however.
This commit implements LTO for rust leveraging LLVM's passes. What this means
is:
* When compiling an rlib, in addition to insdering foo.o into the archive, also
insert foo.bc (the LLVM bytecode) of the optimized module.
* When the compiler detects the -Z lto option, it will attempt to perform LTO on
a staticlib or binary output. The compiler will emit an error if a dylib or
rlib output is being generated.
* The actual act of performing LTO is as follows:
1. Force all upstream libraries to have an rlib version available.
2. Load the bytecode of each upstream library from the rlib.
3. Link all this bytecode into the current LLVM module (just using llvm
apis)
4. Run an internalization pass which internalizes all symbols except those
found reachable for the local crate of compilation.
5. Run the LLVM LTO pass manager over this entire module
6a. If assembling an archive, then add all upstream rlibs into the output
archive. This ignores all of the object/bitcode/metadata files rust
generated and placed inside the rlibs.
6b. If linking a binary, create copies of all upstream rlibs, remove the
rust-generated object-file, and then link everything as usual.
As I have explained in #10741, this process is excruciatingly slow, so this is
*not* turned on by default, and it is also why I have decided to hide it behind
a -Z flag for now. The good news is that the binary sizes are about as small as
they can be as a result of LTO, so it's definitely working.
