Rename `Ty::is_ty_infer` -> `Ty::is_ty_or_numeric_infer`
Makes sure people are aware that they may have a type variable *or* an int/float variable.
r? `@oli-obk` https://github.com/rust-lang/rust/pull/106322#issuecomment-1376913539 but I could instead implement your solution, let me know.
(This will conflict with #106322 for now, ignore that 😄)
Render missing generics suggestion verbosely
It's a bit easier to read like this, especially ones that are appending new generics onto an existing list, like ": `, T`" which render somewhat poorly inline.
Also don't suggest `dyn` as a type parameter to add, even if technically that's valid in edition 2015.
The previous version added both `EF_RISCV_FLOAT_ABI_DOUBLE` and
`EF_RISCV_RVC` if the "D" extension was enabled on riscv64 targets.
riscv32 targets were not accounted for. This patch changes this
so that:
- Only add `EF_RISCV_RVC` if the "C" extension is enabled
- Add `EF_RISCV_FLOAT_ABI_SINGLE` if the "F" extension is enabled
and the "D" extension is not
- Add these ELF flags for riscv32 as well
When the return type of a function call depends on the type of an
argument, e.g.
```
fn foo<T>(x: T) -> T {
x
}
```
and the expected type is set due to either an explicitly typed
binding, or because the call to the function is in a tail position
without semicolon, the current error implies that the argument in the
call has the wrong type.
This new hint highlights that the expected type doesn't match the
returned type, which matches the argument type, and that that's why
we're flagging the argument type.
Fixes#43608.
This prevents differences in local environments, which may (for example)
end up with a longer backtrace with more digits in the backtrace prefix,
as happened to me. While we're at it, clean more of the output up,
including the exact location of the error in the compiler.
Migrate `rustc_lint` lint diagnostics
Part 2 of [Migrate `rustc_lint` errors to `SessionDiagnostic`](https://github.com/rust-lang/rust/pull/100776)
r? `@davidtwco`
# TODO
- [x] Refactor some lints manually implementing `DecorateLint` to use `Option<Subdiagnostic>`.
- [x] Add `#[rustc_lint_diagnostics]` to lint functions in `context.rs`.
- [x] Migrate `hidden_unicode_codepoints.rs`.
- [x] Migrate `UnsafeCode` in `builtin.rs`.
- [x] Migrate the rest of `builtin.rs`.
