Update RLS
Should fix the RLS test breakage.

1. When the invalid condition is hit, write out the relevant variables too
2. In compile-fail/parse-fail tests, check for ICE first, so the invalid
error patterns won't mask our ICE output.
|
|
This isn't a perfect heuristic, but since the amount of run-fail tests
is far lower than run-pass tests for now, it should be sufficient to
ensure that we don't run into CI limits. This makes it possible to run
the test binary manually (e.g., under gdb/lldb) if it failed to attempt
to find out why.
|
|
This should save a lot of space on musl test cases (whose standard library
are linked statically).

Update book
This PR does two things:
1. update the book to include https://github.com/rust-lang/book/pull/1088
2. update to mdbook 0.1
Both of these things are big changes, so I want to land them now, well before the next branch, so we can kick the tires.
------------------------------
Locally, I'm seeing some weirdness around the reference and this:
Putting this PR up so others can try and build and see if it reproduces for them.

ui tests: diff from old (expected) to new (actual) instead of backwards.
Previously `actual` was "old" and `expected` was "new" which resulted in `+` before `-`.
AFAIK all diff tools put `-` before `+`, which made the previous behavior *very confusing*.

Use a range to identify SIGSEGV in stack guards
Previously, the `guard::init()` and `guard::current()` functions were
returning a `usize` address representing the top of the stack guard,
respectively for the main thread and for spawned threads. The `SIGSEGV`
handler on `unix` targets checked if a fault was within one page below that
address, if so reporting it as a stack overflow.
Now `unix` targets report a `Range<usize>` representing the guard memory,
so it can cover arbitrary guard sizes. Non-`unix` targets which always
return `None` for guards now do so with `Option<!>`, so they don't pay any
overhead.
For `linux-gnu` in particular, the previous guard upper-bound was
`stackaddr + guardsize`, as the protected memory was *inside* the stack.
This was a glibc bug, and starting from 2.27 they are moving the guard
*past* the end of the stack. However, there's no simple way for us to know
where the guard page actually lies, so now we declare it as the whole range
of `stackaddr ± guardsize`, and any fault therein will be called a stack
overflow. This fixes #47863.

Add line numbers and columns to error messages spanning multiple files
If an error message is emitted that spans several files, only the
primary file currently has line and column data attached. This is
useful information, even in files other than the one in which the error
occurs. We can often work out which line and column the error
corresponds to in other files — in this case it is helpful to add them
(in the case of ambiguity, the first relevant line/column is picked,
which is still helpful than none).

This commit introduces a separately compiled backend for Emscripten, avoiding
compiling the `JSBackend` target in the main LLVM codegen backend. This builds
on the foundation provided by #47671 to create a new codegen backend dedicated
solely to Emscripten, removing the `JSBackend` of the main codegen backend in
the process.
A new field was added to each target for this commit which specifies the backend
to use for translation, the default being `llvm` which is the main backend that
we use. The Emscripten targets specify an `emscripten` backend instead of the
main `llvm` one.
There's a whole bunch of consequences of this change, but I'll try to enumerate
them here:
* A *second* LLVM submodule was added in this commit. The main LLVM submodule
will soon start to drift from the Emscripten submodule, but currently they're
both at the same revision.
* Logic was added to rustbuild to *not* build the Emscripten backend by default.
This is gated behind a `--enable-emscripten` flag to the configure script. By
default users should neither check out the emscripten submodule nor compile
it.
* The `init_repo.sh` script was updated to fetch the Emscripten submodule from
GitHub the same way we do the main LLVM submodule (a tarball fetch).
* The Emscripten backend, turned off by default, is still turned on for a number
of targets on CI. We'll only be shipping an Emscripten backend with Tier 1
platforms, though. All cross-compiled platforms will not be receiving an
Emscripten backend yet.
This commit means that when you download the `rustc` package in Rustup for Tier
1 platforms you'll be receiving two trans backends, one for Emscripten and one
that's the general LLVM backend. If you never compile for Emscripten you'll
never use the Emscripten backend, so we may update this one day to only download
the Emscripten backend when you add the Emscripten target. For now though it's
just an extra 10MB gzip'd.
Closes #46819

rustc: Load the `rustc_trans` crate at runtime
Building on the work of #45684 this commit updates the compiler to
unconditionally load the `rustc_trans` crate at runtime instead of linking to it
at compile time. The end goal of this work is to implement #46819 where rustc
will have multiple backends available to it to load.
This commit starts off by removing the `extern crate rustc_trans` from the
driver. This involved moving some miscellaneous functionality into the
`TransCrate` trait and also required an implementation of how to locate and load
the trans backend. This ended up being a little tricky because the sysroot isn't
always the right location (for example `--sysroot` arguments) so some extra code
was added as well to probe a directory relative to the current dll (the
rustc_driver dll).
Rustbuild has been updated accordingly as well to have a separate compilation
invocation for the `rustc_trans` crate and assembly it accordingly into the
sysroot. Finally, the distribution logic for the `rustc` package was also
updated to slurp up the trans backends folder.
A number of assorted fallout changes were included here as well to ensure tests
pass and such, and they should all be commented inline.

Change the --unpretty flag to -Z unpretty
First PR :smile: !
-Z unpretty no longer requires -Z unstable-options.
Also, I mildly changed the syntax of the flag to match the other -Z flags. All uses of the flag take the form `unpretty=something` where something can either `string` or `string=string` (see the help messages of the CLI).

Check for deadlinks from the summary during book generation
Previously, any deadlinks from a book's SUMMARY.md wouldn't
cause any errors or warnings or similar but mdbook would simply
create a page with blank content.
This has kept bug #47394 hidden. It should have been detected
back in the PR when those wrongly named files got added to the
book.
PR #47414 was one component of the solution. This change
is a second line of defense for the unstable book and a first
line of defense for any other book.
We also update mdbook to the most recent version.

add target/ to ignored tidy dirs
Sometimes you get a target directory from running cargo in the rust repo (the root is `src/`), and it contains generated files. Just whitelist it since it causes tidy to spew warnings uncontrollably.

This'll probably have a bunch of build errors, so let's try and head those off
and find them sooner rather than later!

Test rustdoc js
Add tests for the rustdoc search. It was heavily required because of all the recent breaking changes that happened while I went through improvements in doc search (add search in/for generic search for example).

Update rust-installer for streaming parallelism
Pull in rust-lang/rust-installer#76 to get streamed tarball generation,
rather than batching it all in memory, while still getting the benefit
of compressing in parallel.

implement "only-<platforms>" for test headers
This patch implements "only-<platforms>" for tests headers using which one can
specify just the platforms on which the test should run rather than listing all
the platforms to ignore using "ignore-<platforms>".
This fixes #33581 and fixes #47459.

Report errors instead of panic!() when linkcheck encounters absolute paths
The RBE contained some absolute links that failed the link check in #46196. Diagnosing these issues was needlessly complicated, thanks to the linkchecker just panicing instead of reporting proper errors.
This PR replaces the panic with a proper `*errors = true` + error message handling.
The linkchecker itself doesn't have any tests so I intentionally didn't touch anything else than the code that previously did the `panic!()`. A small code quality improvement might be made by binding the `Path::new(base).join(url)` into a variable before the for-loop and using this resolved url in both the for loop and the error message.

The function parse_cfg_prefix() is not really parsing. It's just checking
whether the prefix is present or not. So the new function name as suggested by
@Mark-Simulacrum is better.
