mgca: Lower all const paths as `ConstArgKind::Path`
When `#![feature(min_generic_const_args)]` is enabled, we now lower all
const paths in generic arg position to `hir::ConstArgKind::Path`. We
then lower assoc const paths to `ty::ConstKind::Unevaluated` since we
can no longer use the anon const expression lowering machinery. In the
process of implementing this, I factored out `hir_ty_lowering` code that
is now shared between lowering assoc types and assoc consts.
This PR also introduces a `#[type_const]` attribute for trait assoc
consts that are allowed as const args. However, we still need to
implement code to check that assoc const definitions satisfy
`#[type_const]` if present (basically is it a const path or a
monomorphic anon const).

Support raw-dylib link kind on ELF
raw-dylib is a link kind that allows rustc to link against a library without having any library files present.
This currently only exists on Windows. rustc will take all the symbols from raw-dylib link blocks and put them in an import library, where they can then be resolved by the linker.
While import libraries don't exist on ELF, it would still be convenient to have this same functionality. Not having the libraries present at build-time can be convenient for several reasons, especially cross-compilation. With raw-dylib, code linking against a library can be cross-compiled without needing to have these libraries available on the build machine. If the libc crate makes use of this, it would allow cross-compilation without having any libc available on the build machine. This is not yet possible with this implementation, at least against libc's like glibc that use symbol versioning. The raw-dylib kind could be extended with support for symbol versioning in the future.
This implementation is very experimental and I have not tested it very well. I have tested it for a toy example and the lz4-sys crate, where it was able to successfully link a binary despite not having a corresponding library at build-time.
I was inspired by Björn's comments in https://internals.rust-lang.org/t/bundle-zig-cc-in-rustup-by-default/22096/27

triagebot.toml: Don't label `test/rustdoc-json` as A-rustdoc-search
This happened because `test/rustdoc-js` is a prefix of `test/rustdoc-json`, and triagebot works on prefixes.
Maybe this should be fixed in triagebot, but this works now.
This happened on #137956 and #137955.

Always allow rustdoc-json tests to contain long lines
The rustdoc-json test syntax often requires very long lines, so the checks for long lines aren't really useful.
`@aDotInTheVoid` told me she'd like this and
r? jieyouxu
you're gonna tell me that the implementation is terrible. at least the performance seems reasonable: 2.5s after and 2.5s before.

A few cleanups after the removal of `cfg(not(parallel))`
I noticed a few small things that are no longer needed after the removal of `cfg(not(parallel))` in #132282.
One of the later changes adjusts several imports, so viewing the changes individually is recommended.

do not build additional stage on compiler paths
When calling `x build compiler (or rustc) --stage N` bootstrap builds stage N+1 compiler, which is clearly not what we requested. This doesn't happen when running `x build --stage N` without explicitly targeting the compiler.
The changes applied fix this issue.

Future incompatibility warning `unsupported_fn_ptr_calling_conventions`: Also warn in dependencies
Tracking issue: https://github.com/rust-lang/rust/issues/130260
As discussed [in the previous PR](https://github.com/rust-lang/rust/pull/128784/files#r1752533758) now the future incompatibility warning is enabled in dependencies.
The warning was added in 1.83, while this change will get into stable in 1.86, which gives crate authors three versions to fix the warning.

ensure we always print all --print options in help
Closes #137853
Refactors the PRINT_KINDS map into a public const so we always print every option for print. the list is quite long now, and idk if long term we want to keep printing all these options from --help.

Revert "Remove Win SDK 10.0.26100.0 from CI"
Part of #137733.
Resolves #137733.
The remove-latest-windows-sdk workaround workaround should no longer be necessary, now that we bumped (1) cargo `cc` and (2) `rustc_{codegen_ssa,llvm}` `cc`.
This reverts commit 25617c7e695d716d0ecb3cf2366d371441505e47, the remove-latest-windows-sdk workaround from #137753.

Stop using `hash_raw_entry` in `CodegenCx::const_str`
That unstable feature (#56167) completed fcp-close, so the compiler needs to be
migrated away to allow its removal. In this case, `cg_llvm` and `cg_gcc`
were using raw entries to optimize their `const_str_cache` lookup and
insertion. We can change that to separate `get` and (on miss) `insert`
calls, so we still have the fast path avoiding string allocation when
the cache hits.

Skip `tidy` in pre-push hook if the user is deleting a remote branch
It's kinda annoying when I'm trying to delete remote branches and that triggers `tidy`, so small fix to prevent that.
Hopefully this should be an acceptable amount of complexity to add to this shell script.

Simplify parallelization in test-float-parse
Currently, test case generators are launched in parallel and their test cases also run in parallel, all within the same pool. I originally implemented this with the assumption that there would be an advantage in parallelizing the generators themselves, but this turns out to not really have any benefit.
Simplify things by running generators in series while keeping their test cases parallelized. This makes the code easier to follow, and there is no longer a need for MPSC or multiprogress bars. Additionally, the UI output can be made cleaner.

Remove `:` from `stack-protector-heuristics-effect.rs` Filecheck Pattern
With function sections, the assembly label does not necessarily end in `:`.
Remove trailing `:` to be more consistent with the rest of the existing Filecheck patterns.
```
// CHECK-LABEL: local_string_addr_taken
#[no_mangle]
pub fn local_string_addr_taken(f: fn(&String)) {
let x = String::new();
f(&x);

Fix parsing of ranges after unary operators
Fixes https://github.com/rust-lang/rust/issues/134899.
This PR aligns the parsing for unary `!` and `-` and `*` with how unary `&` is already parsed [here](https://github.com/rust-lang/rust/blob/5c0a6e68cfdad859615c2888de76505f13e6f01b/compiler/rustc_parse/src/parser/expr.rs#L848-L854).

Implement `#[cfg]` in `where` clauses
This PR implements #115590, which supports `#[cfg]` attributes in `where` clauses.
The biggest change is, that it adds `AttrsVec` and `NodeId` to the `ast::WherePredicate` and `HirId` to the `hir::WherePredicate`.
|
|
|
|
With the removal of `cfg(parallel_compiler)`, these are always shared
references and `std::sync::OnceLock`.
|
|
this doesn't fix any bugs, it just looks more consistent with the other impl's
|
|
|
|
Otherwise this test will include a future incompatibility warning
on some targets but not others.
|
|
|
|
This was left to only warn in the current crate to give users
a chance to update their code. Now for 1.86 we also warn users
depending on those crates.
|
|
With the removal of `cfg(parallel_compiler)`, these parameters are never
considered unused.

test(codegen): add looping_over_ne_bytes test for #133528
Adds test for #133528.
I renamed the function to `looping_over_ne_bytes` to better reflect that it is doing.
I also set the min llvm version to 20 as this was presumably a llvm bug that was fixed in version 20.
I didn't tie the test to any specific architecture, as we are testing llvm output.
