Display better snippet for invalid char literal Given this code: fn main() { let _ = 'abcd'; } The compiler would give a message like: error: character literal may only contain one codepoint: '; let _ = 'abcd'; ^~ With this change, the message now displays: error: character literal may only contain one codepoint: 'abcd' let _ = 'abcd' ^~~~~~ Fixes #30033 2016-01-07 10:12:28 -06:00			`// This test needs to the last one appearing in this file as it kills the parser`

Provide a span if main function is not present in crate Unfortunately, the diagnotic machinery does not cope well with an empty span which can happen if the crate is empty, in which case we merely set a spanless note. 2019-09-08 12:06:49 -05:00
