(this currently produces malformed mir: we call `eq` with first argument not being a reference)
Do not accept the following
```rust
macro_rules! lexes {($($_:tt)*) => {}}
lexes!(🐛"foo");
```
Before, invalid emoji identifiers were gated during parsing instead of lexing in all cases, but this didn't account for macro expansion of literal prefixes.
Fix rust-lang#123696.
It's required for the next commit. Note that you can still have `G = &H`, since there are implementations of all the graph traits for references.
Introduce perma-unstable `wasm-c-abi` flag Now that `wasm-bindgen` v0.2.88 supports the spec-compliant C ABI, the idea is to switch to that in a future version of Rust. In the meantime it would be good to let people test and play around with it. This PR introduces a new perma-unstable `-Zwasm-c-abi` compiler flag, which switches to the new spec-compliant C ABI when targeting `wasm32-unknown-unknown`. Alternatively, we could also stabilize this and then deprecate it when we switch. I will leave this to the Rust maintainers to decide. This is a companion PR to rust-lang#117918, but they could be merged independently. MCP: rust-lang/compiler-team#703 Tracking issue: rust-lang#122532
…, r=compiler-errors Correctly change type when adding adjustments on top of `NeverToAny` I'm concerned that the check only caught the problem with `fallback = !`, because at least MIR contained `<() as PartialEq>::eq(move _5, move _7)` where `_5: ()`. I rediscovered the issue when looking at rust-lang#123482's crater run. r? compiler-errors Fixes rust-lang#120600
Properly handle emojis as literal prefix in macros

…r, r=wesleywiser Add an opt-in to store incoming edges in `VecGraph` + misc r? ``@fmease`` needed for rust-lang#123939
…errors Fix negating `f16` and `f128` constants Make `f16` and `f128` constants respect `neg` in `parse_float_into_scalar`. Tracking issue: rust-lang#116909 ``@rustbot`` label +F-f16_and_f128
…rieril Fix ICE when there is a non-Unicode entry in the incremental crate directory Fix the ICE that occurs when there is a non-Unicode entry in the incremental crate directory by replacing uses of `to_string_lossy` + `assert_no_characters_lost` with `to_str`. The added test would cause the compiler to ICE before this PR.
