@eddyb

Do not promote constants that contain unpromotable code r? @eddyb cc @nikomatsakis I'll add more tests, just getting this out for a crater run

oli-obk · 2018-06-18T14:24:56Z

@rust-lang/infra Can you start a check-only crater run?

kennytm · 2018-06-18T14:28:16Z

cc @pietroalbini ↑

pietroalbini · 2018-06-18T15:02:09Z

Check-only Crater run started on crater-1. Should finish in ~2 days.

pietroalbini · 2018-06-20T19:54:39Z

Hi @oli-obk (crater requester), @eddyb (PR reviewer)! Crater results are at: http://cargobomb-reports.s3.amazonaws.com/pr-51570/index.html. 'Blacklisted' crates (spurious failures etc) can be found here. If you see any spurious failures not on the list, please make a PR against that file.

(interested observers: Crater is a tool for testing the impact of changes on the crates.io ecosystem. You can find out more at the repo if you're curious)

pietroalbini · 2018-06-20T19:58:58Z

Out of the crates previously building, 3 crates regressed:

amxml (build log)
const-concat (build log)
type-info (build log) and type-info-derive (build log)

No spurious failure.

oli-obk · 2018-06-26T12:25:57Z

I opened a PR to type-info to proactively have them work around the breakage that this PR would introduce if merged.

oli-obk · 2018-06-28T15:00:31Z

src/test/ui/const-eval/unpromotable_constant.rs

+
+
+fn main() {
+    let x: &'static usize = &FOO; //~ ERROR does not live long enough


So we discussed this at the compiler meeting, and constants should be promoted irrelevant of the constant's body in case the constant's value is never inspected.

Examples like the one below (&(FOO % 42)) will still not get promoted.

Examples like &SomeStruct { a: FOO } will get promoted, because the value is only copied, not inspected.

AFAIK @oli-obk decided to do this somewhat differently, based on various discussions after my blog post.
