we should update rustc and stick to it as long as possible
I'm going to do that rebase today, unless someone is already working on it
Thank you, @cuviper!
It would be great to get this into the next beta which branches pretty soon, I think (right, @simulacrum?)
Tuesday
:+1:
OK, just did the source rebase, and it was straightforward
as soon as I sanity-check the build locally, I'll push the branch and PR it
As for getting 9.0 into the next beta, we might make it if bors is fast enough, but there's only one tangible change:
https://github.com/rust-lang/llvm-project/compare/rustc/9.0-2019-07-12..rust-lang:rustc/9.0-2019-09-19#diff-def44c1ae4caac889ffb06e1fa6c446a
corresponding to https://reviews.llvm.org/D67306
we somehow end up with a branch to a deleted MBB. I'm not sure how this doesn't crash the compiler.
... when are we rewriting LLVM in Rust?
I believe that change is only relevant for asm goto, so doesn't affect rust either.
Thanks for taking care of this, @cuviper !
