The test cases src/test/mir-opt/building/custom/consts.rs and src/test/mir-opt/const_prop/mutable_variable_no_prop.rs are currently failing on big-endian platforms as the binary encoding of some constants is hard-coded in the MIR test files. Fix this by choosing constant values that have the same encoding on big- and little-endian platforms. The test case src/test/mir-opt/issues/issue_75439.rs is failing as well, but since the purpose of the test is to validate handling of big-endian integer encodings on a little-endian platform, it does not make much sense to run it on big-endian platforms in the first place - we can just ignore it there. Fixed part of rust-lang#105383.
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 rust-lang#43608.
When we have already suggested bounds that imply the about to be suggested bound, skip them.
This commit updates the wasi-libc revision used to build with the wasm32-wasi target. This notably pulls in WebAssembly/wasi-libc#377 which is needed to fix a use case I've been working on recently. This should be a relatively small update hopefully and is not expected to have any user impact.
I encountered an instance where an `FnPtr` implemented a trait, but I was passing an `FnDef`. To the end user, there is really no way to differentiate each of them, but it is necessary to cast to the generic function in order to compile. It is thus useful to suggest `as` in the help note, (even if the Fn output implements the trait).
… r=Mark-Simulacrum Fix mir-opt tests for big-endian platforms The test cases src/test/mir-opt/building/custom/consts.rs and src/test/mir-opt/const_prop/mutable_variable_no_prop.rs are currently failing on big-endian platforms as the binary encoding of some constants is hard-coded in the MIR test files.

tidy: Don't include wasm32 in compiler dependency check This changes the tidy compiler dependency check so that it does not include wasm32-unknown-unknown dependencies in the PERMITTED_RUSTC_DEPENDENCIES. This just helps keep the list cleaner under the assumption that the compiler will never work on wasm32-unknown-unknown. This also fixes a bug in the check to verify there are no unused dependencies in the PERMITTED_RUSTC_DEPENDENCIES. Previously the check was verifying that the dependency was used *anywhere* in the workspace, when it should have been checking if it was used for the compiler. There's also just a little general cleanup here. For example, the old `normal_deps_of_r` function was changed a while ago to return *all* dependencies, but the function name and description wasn't updated to remove `normal_`.
…, r=cjgillot Emit a single error for contiguous sequences of unknown tokens Closes rust-lang#106101 On encountering a sequence of identical source characters which are unknown tokens, note the amount of subsequent characters and advance past them silently.

…r=cjgillot Add note when `FnPtr` vs. `FnDef` impl trait I encountered an instance where an `FnPtr` implemented a trait, but I was passing an `FnDef`. I was confused for an hour and to examine the source code of the trait's crate's tests in order to understand how to cast it properly (it didn't help that it was behind a reference). To the end user, it might not be immediately obvious that they are different and how to convert from an `FnDef` to an `FnPtr`, but it is necessary to cast to the generic function in order to compile. It is thus useful to suggest `as` in the help note, (even if the `Fn` output implements the trait).
Emit a hint for bad call return types due to generic arguments

…lacrum Use GitHub yaml templates for ICE, Docs and Diagnostics tickets The GitHub yaml templates allow us to define HTML forms with validation for issue templates, instead of the current markdown based templates which only let us introduce text into the user editable text area. The form lets us make some fields mandatory, as well as add text that won't pollute the user's text and titles that won't be interfered with by enterprising users.
