Implement partial support for non-lifetime binders
This implements support for non-lifetime binders. It's pretty useless currently, but I wanted to put this up so the implementation can be discussed.
Specifically, this piggybacks off of the late-bound lifetime collection code in `rustc_hir_typeck::collect::lifetimes`. This seems like a necessary step given the fact we don't resolve late-bound regions until this point, and binders are sometimes merged.
Q: I'm not sure if I should go along this route, or try to modify the earlier nameres code to compute the right bound var indices for type and const binders eagerly... If so, I'll need to rename all these queries to something more appropriate (I've done this for `resolve_lifetime::Region` -> `resolve_lifetime::ResolvedArg`)

This is somewhat important because LLVM enables the pass based on
target architecture, but support by the target OS also matters.
For example, XRay attributes are processed by codegen for macOS
targets, but Apple linker fails to process relocations in XRay
data sections, so the feature as a whole is not supported there
for the time being.

Apply the diagnostic migration lint to more functions on `Session`.

Also update tests

Check AArch64 branch-protection earlier in the pipeline.
As suggested in #93516.

Always evaluate vecs of subdiagnostics eagerly

Refine when invalid prefix case error arises
Fix cases where the "invalid base prefix for number literal" error arises with suffixes that look erroneously capitalized but which are actually invalid.

Remove useless borrows and derefs
They are nothing more than noise.
<sub>These are not all of them, but my clippy started crashing (stack overflow), so rip :(</sub>

Instead of `ast::Lit`.
Literal lowering now happens at two different times. Expression literals
are lowered when HIR is crated. Attribute literals are lowered during
parsing.
This commit changes the language very slightly. Some programs that used
to not compile now will compile. This is because some invalid literals
that are removed by `cfg` or attribute macros will no longer trigger
errors. See this comment for more details:

This way we comply with the Coherence rule given that IntoDiagnostic trait is defined in rustc_errors, and almost all other crates depend on it.

FIX - ambiguous Diagnostic link in docs
UPDATE - rename diagnostic_items to IntoDiagnostic and AddToDiagnostic
[Gardening] FIX - formatting via `x fmt`
FIX - rebase conflicts. NOTE: Confirm wheather or not we want to handle TargetDataLayoutErrorsWrapper this way
DELETE - unneeded allow attributes in Handler method
FIX - broken test
FIX - Rebase conflict
UPDATE - rename residual _SessionDiagnostic and fix LintDiag link
|
|
Also renames:
- sym::AddSubdiagnostic to sym:: Subdiagnostic
- rustc_diagnostic_item = "AddSubdiagnostic" to rustc_diagnostic_item = "Subdiagnostic"

with rustc_lint_diagnostic
This commit removes the allows rules for the SessionDiagnostic lint
that were being used in the session.rs file.
Thanks to the PR #101230 we do not need to annotate the methods with
the allow rule as they are part of the diagnostic machinery.

This commit migrates the errors in the function check_expected_reuse
to use the new SessionDiagnostic. It also does some small refactor
for the IncorrectCguReuseType to include the 'at least' word in the
fluent translation file
|
|
This commit migrates around 80% of the parse file to use SsessionDiagnostic
We still have to migrate struct_err and struct_warn.
|
|
This commit migrates the errors that indicates an incorrect
CGU type and the fatal error that indicates that a CGU has
not been correctly recorded
