Improve syntax of `newtype_index`
This makes it more like proper Rust and also makes the implementation a lot simpler.
Mostly just turns weird flags in the body into proper attributes.
It should probably also be converted to an attribute macro instead of function-like, but that can be done in a future PR.
Add `IMPLIED_BOUNDS_ENTAILMENT` lint
Implements a lint (#105572) version of the hard-error introduced in #105483. Context is in that PR.
r? `@lcnr`
cc `@oli-obk` who had asked for this to be a lint first
Not sure if this needs to be an FCP, since it's a lint for now.
When building with Fat LTO and BTI enabled on aarch64, the BTI is set to
`Module::Min` for alloc shim but is set to `Module::Error` for the
crate. This was fine when we were using LLVM-14 but LLVM-15 changes it's
behaviour to support for compiling with different `mbranch-protection`
flags.

Revert #103880 "Use non-ascribed type as field's type in mir"
This PR prepares a revert for #103880 to fix#105809, #105881, #105886 and others (like the duplicates of the first one), in case an actual fix can't get done today.
I've also added the MCVE from #105809. There is no MCVE for the #105881 and #105886 ICEs yet however, so there are no tests for them here, although we'll need one before relanding the original changes.
Were this PR to land, it would also reopen#96514 as it was fixed by the original PR.
Opening as draft to allow time for a possible fix.
r? `@jackh726`
The src/test/ui/issues/issue-74564-if-expr-stack-overflow.rs test case
added to verify https://github.com/rust-lang/rust/issues/74564 still
crashes with a stack overflow on s390x-ibm-linux.
Symptom is a very deep recursion in compiler/rustc_lint/src/early.rs:
fn visit_expr(&mut self, e: &'a ast::Expr) {
self.with_lint_attrs(e.id, &e.attrs, |cx| {
lint_callback!(cx, check_expr, e);
ast_visit::walk_expr(cx, e);
})
}
(where walk_expr recursively calls back into visit_expr). The crash
happens at a nesting depth of over 17000 stack frames when using the
default 8 MB stack size on s390x.
This patch fixes the problem by adding a ensure_sufficient_stack
call to the with_lint_attrs routine (which also should take care
of all the other mutually recursive visitors here).
Fixes part of https://github.com/rust-lang/rust/issues/105383.
Following the s390x ELF ABI and based on the clang implementation,
provide appropriate definitions of va_list in library/core/src/ffi/mod.rs
and va_arg handling in compiler/rustc_codegen_llvm/src/va_arg.rs.
Fixes the following test cases on s390x:
src/test/run-make-fulldeps/c-link-to-rust-va-list-fn
src/test/ui/abi/variadic-ffi.rs
Fixes https://github.com/rust-lang/rust/issues/84628.
Revert "Replace usage of `ResumeTy` in async lowering with `Context`"
Reverts rust-lang/rust#105250
Fixes: #105501
Following instructions from [forge](https://forge.rust-lang.org/compiler/reviews.html#reverts).
This change introduced a breaking change that is not actionable nor relevant, and is blocking updates to our toolchain. Along with other comments on the CL marking issues that are fixed by reverts, reverting is best until these issues can be resolved
cc. `@Swatinem`
Add long error docs for `E0460` and `E0457`
Final docs for errors in #61137 that have UI tests, my next PRs will also add these tests.
r? ``@GuillaumeGomez``
if 2 errors of the kind and ident and span of the ident, b1, b2 and misc1 misc2 are the same
then these 2 ambiguity errors matched
prevent identical ambiguity error from pushing into vector of ambiguity_errors
this will fix#105177

Revert "Introduce lowering_arena to avoid creating AST nodes on the fly"
This reverts commit d9a1faaa9c (#101499).
This was originally part of #101345 which has now been closed as a different approach is taken now.
r? `@oli-obk`
cc `@spastorino`
print argument name in arg mismatch if possible
A bit more contextual than just `/* value */`, at least when the argument is named something related to its context.
The UI test cases are... not super convincing, but also they're minimized tests.
Remove the `..` from the body, only a few invocations used it and it's
inconsistent with rust syntax.
Use `;` instead of `,` between consts. As the Rust syntax gods inteded.
This removes the `custom` format functionality as its only user was
trivially migrated to using a normal format.
If a new use case for a custom formatting impl pops up, you can add it
back.
