df701a292c Querify global_backend_features
At the very least this serves to deduplicate the diagnostics that are
output about unknown target features provided via CLI.

c97c216efd Direct users towards using Rust feature names in CLI
If they are trying to use features rustc doesn't yet know about,
request a feature request.

Additionally, also warn against using feature names without leading `+`
or `-` signs.

8d6f527530 Auto merge of #94299 - oli-obk:stable_hash_ty, r=michaelwoerister
Caching the stable hash of Ty within itself

Instead of computing stable hashes on types as needed, we compute it during interning.

This way we can, when a hash is requested, just hash that hash, which is significantly faster than traversing the type itself.

We only do this for incremental for now, as incremental is the only frequent user of stable hashing.

As a next step we can try out

* moving the hash and TypeFlags to Interner, so projections and regions get the same benefit (tho regions are not nested, so maybe that's not a good idea? Would be nice for dedup tho)
* start comparing types via their stable hash instead of their address?

99a77798d3 Fix inconsistent symbol mangling of integers constants with -Zverbose
The `PrettyPrinter` changes formatting of array size and integer
constants based on `-Zverbose`, so its implementation cannot be used in
legacy symbol mangling.

Rollup merge of #94248 - compiler-errors:fix-while-loop-bad-delay, r=petrochenkov
Fix ICE when passing block to while-loop condition

We were incorrectly delaying a bug when we passed _any_ block (that evaluated to `()`) to a while loop. This PR makes the check a bit more sophisticated.

We should only suppress the error here in cases that are equivalent to those we find in #93574 (i.e. only while loop conditions that have destructuring assignment expressions in them).

Fixes #93997
cc `@estebank` who added this code

I would not be opposed to removing the delay-bug altogether, and just emitting this error always. I much prefer duplicate errors over no errors.

Only create a single expansion for each inline integration.

The inlining integrator used to create one expansion for each span from the callee body.
This PR reverses the logic to create a single expansion for the whole call,
which is more consistent with how macro expansions work for macros.

This should remove the large memory regression in #91743.

dce14cfacc Remove LLVM attribute removal
This was necessary before, because `declare_raw_fn` would always apply
the default optimization attributes to every declared function,
and then `attributes::from_fn_attrs` would have to remove the default
attributes in the case of, e.g. `#[optimize(speed)]` in a `-Os` build.

However, every relevant callsite of `declare_raw_fn` (i.e. where we
actually generate code for the function, and not e.g. a call to an
intrinsic, where optimization attributes don't [?] matter)
calls `from_fn_attrs`, so we can simply remove the attribute setting
from `declare_raw_fn`, and rely on `from_fn_attrs` to apply the correct
attributes all at once.

Apply noundef attribute to all scalar types which do not permit raw init

Beyond `&`/`&mut`/`Box`, this covers `char`, enum discriminants, `NonZero*`, etc.
All such types currently cause a Miri error if left uninitialized,
and an `invalid_value` lint in cases like `mem::uninitialized::<char>()`.

Note that this _does not_ change whether or not it is UB for `u64` (or
other integer types with no invalid values) to be undef.

Fixes (partially) #74378.

Rollup merge of #94415 - bjorn3:cfg_default_backend, r=Mark-Simulacrum
Use the first codegen backend in the config.toml as default

It is currently hard coded to llvm if enabled and cranelift otherwise.
This made some sense when cranelift was the only alternative codegen
backend. Since the introduction of the gcc backend this doesn't make
much sense anymore. Before this PR bootstrapping rustc using a backend
other than llvm or cranelift required changing the source of
rustc_interface. With this PR it becomes a matter of putting the right
backend as first enabled backend in config.toml.

Document that pre-expansion lint passes are softly deprecated

The pre-expansion lint pass has been softly deprecated since https://github.com/rust-lang/rust/pull/69838. Every once in a while I see someone mention it as a possibility, only get the feedback that it's deprecated. This PR officially documents that the method is soft deprecated to have a single point of truth for it.

That's it. Have a great rest of the day 🙃
