incr.comp.: Bring back output of -Zincremental-info. by michaelwoerister · Pull Request #45063 · rust-lang/rust

michaelwoerister · 2017-10-06T14:06:15Z

This got kind lost during the transition to red/green.

I also switched back from eprintln!() to println!() since the former never actually produced any output. I suspect this has to do with libterm somehow monopolizing stderr.

The test_inherit_env test failed on Windows. I guess the it has something to do with the commit message. @michaelwoerister Could you move the table into a separate comment, and then bors-retry?

I guess the it has something to do with the commit message. @michaelwoerister Could you move the table into a separate comment, and then bors-retry?

wat? :) Thanks for pointing that out, I'd never have known what's going on here.

@nikomatsakis

…r=nikomatsakis incr.comp.: Bring back output of -Zincremental-info. This got kind lost during the transition to red/green. I also switched back from `eprintln!()` to `println!()` since the former never actually produced any output. I suspect this has to do with `libterm` somehow monopolizing `stderr`. r? @nikomatsakis

@nikomatsakis

incr.comp.: Use a set implementation optimized for small item counts for deduplicating read-edges. Many kinds of `DepNodes` will only ever have between zero and three edges originating from them (see e.g. #45063 (comment)) so let's try to avoid allocating a `HashSet` in those cases. r? @nikomatsakis

incr.comp.: Bring back output of -Zincremental-info.
