(And other kinds of items).
This brings trait/impl items in line with top-level items in this respect. It means we don't get the attributes when showing error messages for methods, etc. (a good thing, I think). Since attributes have spans it is still easy to create a span for the item + all attributes.
As part of the audit for #22820 the following duplicate feature
gate tests were removed:
* `box_patterns`
* `simd_ffi`
These tests for `box_patterns` and `simd_ffi` were added in #23578,
however there were existing tests in #20723 and #21233 respectively.
As part of the audit for #22820 the following feature gate tests have
been added:
* `negate_unsigned`
* `on_unimplemented`
* `optin_builtin_traits`
* `plugin`
* `rustc_attrs`
* `slice_patterns`
1) Moved 'while' section below 'loop', 'break', and 'continue'; 2) Added information to 'while' and 'for' loops that they interact with 'break' and 'continue' and may have a lifetime label. 3) Clarified labeling syntax on the infinite loops.
skolemize_late_bound_regions essentially copies the entire type (most of the times it shouldn't, but it does), and match_impl runs millions of times.
Times compiling rustc, tested with
$ make -j4 rustc-stage1
$ ( time RUSTFLAGS=-Z time-passes make -j4 rustc-stage2 ) # need LLVM time for calibration
Before:
real 21m44.960s
user 29m38.812s
sys 0m14.944s
After:
real 19m31.445s
user 26m47.260s
sys 0m14.952s
Making this is a 10% performance improvement.
LLVM passes took 867 seconds before, 862 seconds after.
This required fixing the `pretty-rpass-full` tests to have the same `$$(CSREQ$(1)_T_$(2)_H_$(3))` dependencies as the `rpass-full` and `cfail-full` tests. It also required fixing the `run-make/simd-ffi` test to use unique names for its output files.
These functions were intended to be introduced as `#[stable]` as a stable API
was deprecated in favor of them, but they just erroneously forgot the stability
attributes.
Combine the two links, [-] and [+], at top-right corner of the page, to use a single and the same one, so that:
- one less link to be created/displayed
- be consistent with other [-]/[+] links in the same page
- people can easily toggle docs without moving their mouse pointer
I also added tooltips/titles to these links.
Instead of rustc-1.0.0-beta-$triple.tar.gz, betas will be named
rustc-beta-$triple.tar.gz. This will give betas a stable download
URL, prevent old artifacts from accumulating in the dist server's
root directory, and not require the website to be updated every
beta.
As a tradeoff, it will be harder to download previous betas because
they will need to be located in the archives.
I'm still unsure about whether this is the right choice.

The run-pass and pretty run-pass tests could run concurrently, and if they
do, they need to keep their output segregated.
This change might be overkill. We need the suffix for the `pretty` mode,
but we might not need it otherwise. The `debuginfo-lldb` and
`debuginfo-gdb` modes look like they could also need it, but the current
`tests.mk` file happens not to enable both lldb and gdb at the same time,
for incidental reasons.
The problem is that rustdoc searches for external crates using the host
triple, not the target triple. It's actually unclear to me whether this is
correct behavior or not, but it is necessary to get cross-compiled tests
working.
These tests fail, in general, for cross-compilation, because they require
the rustc crates to exist for the target, and they don't. We can't compile
them for the target unless we also compile LLVM for the target (we don't).
Android is a subset of cross-compilation.
The other fulldeps tests, on the other hand, work fine for
cross-compilation, and in fact, are verifying that rustc correctly searches
for a host plugin crate, not a target plugin crate.
