First deprecated in rustc 1.8.0 the intention was to never allow `-Z` flags make
their way to the stable channel (or unstable options). After a year of warnings
we've seen one of the main use cases, `-Z no-trans`, stabilized as `cargo
check`. Otherwise while other use cases remain the sentiment is that now's the
time to start forbidding `-Z` by default on stable/beta.
Closes#31847
Run non-native tests on real device
After #40733, I've made some hacks to the QEMU client-server tools to allow running the tests on a real device when cross compiling Rust. The address and port of the remote server can be set using an environment variable.
I've made this mainly for local testing purposes, if you're interested in merging this, I'd clean it a bit more (eg. renaming the functions from `qemu-` to something else). I'm not asking for CI integration or adding ARM boards to the build system; it's just that I used these modifications and I was wondering if you'd find them useful too.
Remove obsolete --disable-elf-tls configure switch.
Support for disabling ELF-style thread local storage in
the standard library at configure time was removed in
pulls #30417 and #30678, in favour of a member in
the TargetOptions database. The new mentod respects
MACOSX_DEPLOYMENT_TARGET on macOS, addressing the
original use case for this configure optionl
However, those commits left the configure option itself
in place. It's no longer referenced anywhere and can
be removed.
Remove ast-ty-to-ty cache
As discussed on IRC, this basically just removes the cache, and rewrites rustdoc and save-analysis so call into the astconv code. It *might* make sense for this to be a more fine-grained query, but that would (at least) require us to be using `HirId` and not `NodeId`.
(Perhaps I should open a FIXME?)
I didn't measure perf impact (yet?). I did observe that the cache seems to hit *rarely* -- and only in between items (I experimented with a cache "per def-id", but that had zero hits). In other words, every single hit on the cache is a dependency bug, since it is "shuttling" information between items without dependency edges.

Fix @martinhath's mailmap entry
I stumbled upon a name duplication issue in [rust-lang-nursery/thanks](https://github.com/rust-lang-nursery/thanks/), and realized that this problem is easily fixable. I've (hopefully) done the right thing here. It works locally (`git shortlog | grep "Thoresen"` only returns one entry instead of two).
I didn't bother creating an issue in the `thanks` repository, since I did the `.mailmap` editing myself.
Generate XZ-compressed tarballs
Integrate the new `rust-installer` and extend manifests with keys for xz-compressed tarballs.
One of the steps required for https://github.com/rust-lang/rust/issues/21724
There are now two queries: crate and item. The crate one computes the
variance of all items in the crate; it is sort of an implementation
detail, and not meant to be used. The item one reads from the crate one,
synthesizing correct deps in lieu of the red-green algorithm.
At the same time, remove the `variance_computed` flag, which was a
horrible hack used to force invariance early on (e.g. when type-checking
constants). This is only needed because of trait applications, and
traits are always invariant anyway. Therefore, we now change to take
advantage of the query system:
- When asked to compute variances for a trait, just return a vector
saying 'all invariant'.
- Remove the corresponding "inferreds" from traits, and tweak the
constraint generation code to understand that traits are always
inferred.
rustbuild: Sanity-check cmake for sanitizers too
It's possible to build the sanitizers when using an external LLVM, but
we still need cmake for this. Extend the sanity check to look for cmake
whenever sanitizers are enabled too.
