Could not compile rustdoc for i686-pc-windows-msvc again. This PR may have introduced a change that caused this to fail with some probability. Not going to retry.

eddyb · 2017-12-06T09:18:22Z

Is it running out of memory by any chance?

kennytm · 2017-12-06T09:20:14Z

I don't know, the log doesn't track memory use 😞

carols10cents · 2017-12-12T15:15:18Z

Soooo who might have some insight on why rustdoc can't build on appveyor? @rust-lang/infra ? @rust-lang/docs ?

GuillaumeGomez · 2017-12-12T16:43:08Z

Without more logs, it's gonna be complicated...

r? @oli-obk on the last ~~two~~ three commits (also, I'll have to update miri itself, too, right?).

oli-obk · 2017-12-17T08:43:50Z

Awesome! I wanted to do this all along

oli-obk · 2017-12-17T08:56:55Z

Why did you remove the comment?

oli-obk

Threading through the alignments was the original idea. We scrapped it because we thought it would get too intrusive. With all the convenience methods on Align it seems good though

oli-obk · 2017-12-17T09:19:26Z

Just break miri. I want to refactor some of the ty arguments to layout arguments anyway, I'll just do that there

rustc: ensure optimized enums have a properly aligned size. Fixes#46769 by padding the optimized enums wrapping packed data as necessary. Note that this is not the only way to solve this - on nightly, #46436 makes it easier to fix without adding new padding because of the replacement of `packed` flags with a non-redundant scheme. But because it can't be backported, the optimal fix will be in a separate nightly-only PR (#46809).
