2ec323e4c3 Potential fix for Win32 build
It seems in one of rebases I’ve resolved conflicts wrong and left one redundant line, it is absent in current master and it might cause compilation failure by copying file into itself.

3446f28879 Updated compiler-rt
Previous update unfortunately included changes which
broke Android compilation. This update fixes it and
should allow correct compilation of SjLj for iOS and
all builtins for Android.

This removes all remnants of `@` pointers from rustc. Additionally, this removes

2c6caad1ba auto merge of #14878 : vtsatskin/rust/rustdoc-sidebar-click-targets, r=alexcrichton
There was feedback gathered by @bjz which request for larger click targets in the rustdoc sidebar. Here's my attempt at that.

My only concern with this patch is the removal of `<br>` between sidebar links. This may break formatting for text-only viewers of this documentation. If there is a large enough demographic of people that will be affected, perhaps we can try switching the structure of each sidebar block sidebar to an `<ol>` with each item as a `<li>`. 

* Change links to display:block for click larger targets
* Remove linebreaks due to extra space
* Adjust margins so that element spacing stays the same
* Sidebar item hover background colour chosen from `<pre>` styling

d7de4e9aff Enforce stronger guarantees for mutable borrows
Implement the stronger guarantees for mutable borrows from #12624. This
removes the ability to read from a mutably borrowed path for the
duration of the borrow, and enforces a unique access path for any
mutable borrow, for both reads and writes.

This makes mutable borrows work better with concurrent accesses from
multiple threads, and it opens the door for allowing moves out of
mutably borrowed values, as long as a new value is written before the
mutable borrow ends. This also aligns Rust more closely with academic
languages based on substructural types and separation logic.

The most common situation triggering an error after this change is a
call to a function mutably borrowing self with self.field as one of the
arguments. The workaround is to bind self.field to a temporary, but the
need for these temporaries will hopefully go away after #6268 is fixed.

Another situation that triggers an error is using the head expression of
a match in an arm that binds a variable with a mutable reference. The
use of the head expression needs to be replaced with an expression that
reconstructs it from match-bound variables.

This fixes #12624.

d884cc83b0 remove unnecessary PaX detection
Rust no longer has support for JIT compilation, so it doesn't currently
require a PaX MPROTECT exception. The extended attributes are preferred
over modifying the binaries so it's not actually going to work on most
systems like this anyway.

If JIT compilation ends up being supported again, it should handle this
by *always* applying the exception via an extended attribute without
performing auto-detection of PaX on the host. The `paxctl` tool is only
necessary with the older method involving modifying the ELF binary.

ac7b9ddc54 Audit usage of NativeMutex
Once a native mutex has been used once, it is never allowed to be moved again.
This is because some pthreads implementations take pointers inside the mutex
itself.

This commit adds stern wording around the methods on native mutexes, and fixes
one use case in the codebase. The Mutex type in libsync was susceptible to
movement, so the inner static mutex is now boxed to ensure that the address of
the native mutex is constant.

e7f11f20e5 auto merge of #14604 : nikomatsakis/rust/issue-5527-namespace-substs, r=pcwalton
The current setup is to have a single vector of type parameters in
scope at any one time. We then have to concatenate the parameters from
the impl/trait with those of the method. This makes a lot of things
awkward, most notably associated fns ("static fns"). This branch
restructures the substitutions into three distinct namespaces (type,
self, fn). This makes most of the "type parameter management"
trivial. This also sets us up to support UFCS (though I haven't made
any particular changes in that direction in this patch).

Along the way, this patch fixes a few miscellaneous bits of code cleanup:

1. Patch resolve to detect references to out-of-scope type parameters,
   rather than checking for "out of bound" indices during substitution
   (fixes #14603).

2. Move def out of libsyntax into librustc where it belongs. I should have
   moved DefId too, but didn't.
   
3. Permit homogeneous tuples like `(T, T, T)` to be used as fixed-length
   vectors like `[T, ..3]`. This is awfully handy, though public facing.
   I suppose it requires an RFC.

4. Add some missing tests.

9153d8ad6c Introduce VecPerParamSpace and use it to represent sets of types and
parameters

This involves numerous substeps:

1. Treat Self same as any other parameter.
2. No longer compute offsets for method parameters.
3. Store all generic types (both trait/impl and method) with a method,
   eliminating odd discrepancies.
4. Stop doing unspeakable things to static methods and instead just use
   the natural types, now that we can easily add the type parameters from
   trait into the method's polytype.
5. No doubt some more. It was hard to separate these into distinct commits.
