Rollup merge of #103405 - chenyukang:yukang/fix-103381-and-if, r=compiler-errors

2022-11-18T13:13:36+00:00

Detect incorrect chaining of if and if let conditions and recover Fixes #103381

Use `token::Lit` in `ast::ExprKind::Lit`.

2022-11-15T22:41:28+00:00

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: https://github.com/rust-lang/rust/pull/102944#issuecomment-1277476773

Rollup merge of #104223 - fmease:recover-fn-ptr-with-generics, r=estebank

Recover from function pointer types with generic parameter list Give a more helpful error when encountering function pointer types with a generic parameter list like `fn<'a>(&'a str) -> bool` or `fn(T) -> T` and suggest moving lifetime parameters to a `for<>` parameter list. I've added a bunch of extra code to properly handle (unlikely?) corner cases like `for<'a> fn<'b>()` (where there already exists a `for<>` parameter list) correctly suggesting `for<'a, 'b> fn()` (merging the lists). If you deem this useless, I can simplify the code by suggesting nothing at all in this case. I am quite open to suggestions regarding the wording of the diagnostic messages. Fixes #103487. ``@rustbot`` label A-diagnostics r? diagnostics
