Nilstrieb	da26317a8a	Stop mentioning internal lang items in no_std binary errors ... When writing a no_std binary, you'll be greeted with nonsensical errors mentioning lang items like eh_personality and start. That's pretty bad because it makes you think that you need to define them somewhere! But oh no, now you're getting the `internal_features` lint telling you that you shouldn't use them! But you need a no_std binary! What now? No problem! Writing a no_std binary is super easy. Just use panic=abort and supply your own platform specific entrypoint symbol (like `main`) and you're good to go. Would be nice if the compiler told you that, right? This makes it so that it does do that.	2024-01-10 21:18:54 +01:00

bors	aace2dfa37	Auto merge of #115910 - eduardosm:lang-fns-target-features, r=cjgillot ... Prevent using `#[target_feature]` on lang item functions Fixes https://github.com/rust-lang/rust/issues/109411 and also prevents from using `#[target_feature]` on other `fn` lang items to mitigate the concerns from https://github.com/rust-lang/rust/issues/109411#issuecomment-1477030273.	2023-09-22 05:07:45 +00:00

Eduardo Sánchez Muñoz	c599761140	rustc_hir_analysis: add a helper to check function the signature mismatches ... This function is now used to check `#[panic_handler]`, `start` lang item, `main`, `#[start]` and intrinsic functions. The diagnosis produced are now closer to the ones produced by trait/impl method signature mismatch.	2023-09-19 18:15:23 +02:00
