Add a label to point to the lacking macro name definition by linyihai · Pull Request #127557 · rust-lang/rust (original) (raw)

if we just used primary_span.shrink_to_hi()

This is also looks good to me. And it is more consistent between macro_rules! {} and macro_rules!{}, which will always point to the !

Alternatively, find a more "pure" way to express this span (or a similar one) without using bytepos.

I currently have few time to try this.
