(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.
