This commit was created by a combination of scripts and tools:
- an ast-grep script to prefix things in meta with `lib.`,
- a modified nixf-diagnose / nixf combination to remove unused `with
lib;`, and
- regular nixfmt.

Enable the LLVM profiler runtime on macOS by passing `--enable-profiler`
to rustc's configure. This allows cargo-llvm-cov and other coverage tools
to work on Darwin platforms.
The profiler is explicitly disabled for wasm and bpf targets which don't
support it.
Since cross compilers can also build code for the build platform, we
should also install these debug scripts so they are available just like
in our non-cross rustc.
Fixes `libunwind` from not being included due to improper usage of
`lib.optional` by passing a list instead of a single item. Drops the
hack for `llvmPackages` since just passing it through works now.
We also need to symlink libexec when doing fastCross.
It contains rust-analyzer-proc-macro-srv which rust-analyzer needs for proc macro expansion to work.
We want -Cforce-frame-pointers=yes when building rustc itself, but the
bootstrap process does not use cargoSetupHook, so set the bootstrap
config option rust.frame-pointers = true if target is not x86_32.
Note that std is unconditionally compiled with frame pointers. See code
comment for elaboration.
See also #399014 for discussion when we enabled frame pointers for C.
Fixes#405914
Upstream's installation script installs the `docs` component
for every target that is built.
Unfortunately, installing the docs for a target removes the
previous target's docs, ultimately leaving only the docs
of the last target in the list.
In our case, that is a `no_std` target, for which no `alloc`
or `std` docs are built, thus leaving `rustc.doc` without any
standard library docs.
Moving stdenv's `targetPlatform` to the end of the list ensures
we get standard library docs.
They are not doing anything right now. This is in preparation for their
complete removal from the tree.
Note: several changes that affect the derivation inputs (e.g. removal of
references to stub paths in build instructions) were left out. They will
be cleaned up the next iteration and will require special care.
Note: this PR is a result of a mix of ugly regex (not AST) based
automation and some manual labor. For reference, the regex automation
part was hacked in: https://github.com/booxter/nix-clean-apple_sdk

After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.
Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.
A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.
This commit was automatically created and can be verified using
nix-build a08b3a4d19.tar.gz \

In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.
