Right now on the most recent version of LLDB installed on OSX we'll segfault on
all the LLDB tests if this isn't called (unfortunately). Hopefully we've updated
LLDB on the bots to actually get this working everywhere!
Closes#32994
The different generations of ARM floating point VFP correspond to the
LLVM CPU features named `vfp2`, `vfp3`, and `vfp4`; they are now
exposed in Rust under the same names.
This commit fixes some crashes that would occour when checking if the
`vfp` feature exists (the crash occurs because the linear scan of the
LLVM feature goes past the end of the features whenever it searches
for a feature that does not exist in the LLVM tables).
rustdoc: refine cross-crate impl inlining
This changes the current rule that impls within `doc(hidden)` modules aren't inlined, to only inlining impls where the implemented trait and type are reachable in documentation.

rustbuild: Add support for compiletest test suites
This commit adds support in rustbuild for running all of the compiletest test
suites as part of `make check`. The `compiletest` program was moved to
`src/tools` (like `rustbook` and others) and is now just compiled like any other
old tool. Each test suite has a pretty standard set of dependencies and just
tweaks various parameters to the final compiletest executable.
Note that full support is lacking in terms of:
* Once a test suite has passed, that's not remembered. When a test suite is
requested to be run, it's always run.
* The arguments to compiletest probably don't work for every possible
combination of platforms and testing environments just yet. There will likely
need to be future updates to tweak various pieces here and there.
* Cross compiled test suites probably don't work just yet, support for that will
come in a follow-up patch.

grammar: fix
Reading this, one item stood out a bit. Small improvements here.
1. ‘Compile-time’ is not a noun, ‘compilation time’ was meant;
1. Mathematical formulas are best not rendered as code;
1. Use the same tense as in other items.
Reword explanation of 'size' types.
Do not reference machine 'pointers' in explanation of 'size' types.
I think the number of elements that can be directly addressed is a fundamental feature of a machine architecture in its own right. The fact that it coincides with the ‘size’ of a pointer should be viewed as an ‘implementation detail’ ;)
split iter.rs into a directory of (implementation private) modules.
+ mod Adaptor structs
- Private fields need to be available both for them and Iterator
+ iterator (Iterator trait)
+ traits (FromIterator, traits but Iterator itself)
+ range (range related)
+ sources (Repeat, Once, Empty)
rustbuild: Clean more as part of `make clean`
Clean out old documentation as well as the new test/tools directories. Should
prevent a problem that happened this morning where a PR bounced and then it left
docs with "broken links" so all future PRs bounced.
Instead of stripping impls which reference *stripped* items, we keep impls
which reference *retained* items. We do this because when we strip an
item we immediately return, and do not recurse into it - leaving the
contained items non-stripped from the point of view of the `ImplStripper`.
resolve: Improve performance
This fixes#33061 by speeding up searchs through all traits in scope, a bottleneck in `resolve`.
According to my measurements, this PR improves resolution performance by a factor of 3.4x on `librustc`, which almost completely reverses the 3.75x performance regression reported in #33061.

Adjust example for error E0225
Adjust example for error E0225
It's using Copy as a trait object compatible trait, which is not
appropriate, change to use a more typical Read + Send + Sync example.
Also use whitespace around `+`.
This seems appropriate apropos issue #32963
