Previously, the following configuration in settings.json:
"rust-analyzer.workspace.discoverConfig": {
"command": [
"oops",
"develop-json",
"{arg}"
],
"progressLabel": "rust-analyzer",
"filesToWatch": [
"BUCK",
"TARGETS"
]
},
Would previously cause a crash in rust-analyzer:
thread 'LspServer' panicked at crates/rust-analyzer/src/main_loop.rs:776:84:
called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "No such file or directory" }
Instead, use more specific panic messages.
1. Err on unions on derive where it's required.
2. Err on `#[derive(Default)]` on enums without `#[default]` variant.
3. Don't add where bounds `T: Default` when expanding `Default` on enums (structs need that, enums not).
Also, because I was annoyed by that, in minicore, add a way to filter on multiple flags in the line-filter (`// :`). This is required for the `Debug` and `Hash` derives, because the derive should be in the prelude but the trait not.
We used to point to the entire macro call including its token tree if we couldn't upmap the diagnostic to the input
This generally makes things very noisy as the entire macro call will turn red on errors.
Instead, we now macro the path and `!` (bang) token as the error source range which is a lot nicer on the eyes.
Add SIMD funnel shift and round-to-even intrinsics
This PR adds 3 new SIMD intrinsics
- `simd_funnel_shl` - funnel shift left
- `simd_funnel_shr` - funnel shift right
- `simd_round_ties_even` (vector version of `round_ties_even_fN`)
TODO (future PR): implement `simd_fsh{l,r}` in miri, cg_gcc and cg_clif (it is surprisingly hard to implement without branches, the common tricks that rotate uses doesn't work because we have 2 elements now. e.g, the `-n&31` trick used by cg_gcc to implement rotate doesn't work with this because then `fshl(a, b, 0)` will be `a | b`)
