- Sort dependencies and features sections.
- Add `tidy` markers to the sorted sections so they stay sorted.
- Remove empty `[lib`] sections.
- Remove "See more keys..." comments.
Excluded files:
- rustc_codegen_{cranelift,gcc}, because they're external.
- rustc_lexer, because it has external use.
- stable_mir, because it has external use.
Before, it said "global_allocator does nothing". Now it gives you
suggestions for what to do if you want to change the global allocator
(which is likely the main reason you'd be reading the comment).
This is the first (known) step towards starting to use `unix_sigpipe` in
the wild. Eventually, `rustc_driver::set_sigpipe_handler` can be removed
and all clients can use `unix_sigpipe` instead.
For now we just start using `unix_sigpipe` in once place: `rustc`
itself.
It is easy to manually verify this change. If you remove
`#[unix_sigpipe = "sig_dfl"]` and run `./x.py build` you will get an ICE
when you do `./build/x86_64-unknown-linux-gnu/stage1/bin/rustc --help |
false`. Add back `#[unix_sigpipe = "sig_dfl"]` and the ICE disappears
again.
In practice, this doesn't matter very much because the script takes ~no time to run.
But this makes `CARGO_LOG=info` easier to read, and theoretically saves a few milliseconds.
Add Windows application manifest to rustc-main
Windows allows setting some runtime options using a manifest file. The format of the XML file is documented here: https://docs.microsoft.com/en-us/windows/win32/sbscs/application-manifests
The manifest file in this PR does three things:
* Declares which Windows versions we support. This may help avoid unnecessary compatibility shims.
* Uses the UTF-8 code page. While Rust itself uses UTF-16 APIs, other code may rely on the code page.
* Makes the application long path aware (if also enabled by the user). This allows for the current directory to be longer than `PATH_MAX`.
These changes only affect the `rustc` process and not any other DLLs or compiled programs.
Since RFC 3052 soft deprecated the authors field anyway, hiding it from
crates.io, docs.rs, and making Cargo not add it by default, and it is
not generally up to date/useful information, we should remove it from
crates in this repo.
