bors 2a9e0831d6 Auto merge of #91393 - Julian-Wollersberger:lexer_optimization, r=petrochenkov ... Optimize `rustc_lexer` The `cursor.first()` method in `rustc_lexer` now calls the `chars.next()` method instead of `chars.nth_char(0)`. This allows LLVM to optimize the code better. The biggest win is that `eat_while()` is now fully inlined and generates better assembly. This improves the lexer's performance by 35% in a micro-benchmark I made (Lexing all 18MB of code in the compiler directory). But lexing is only a small part of the overall compilation time, so I don't know how significant it is. Big thanks to criterion and `cargo asm`.		2021-12-03 13:20:14 +00:00
