@Mark-Simulacrum, a try build will use the src/ci/docker/dist-x86_64-linux/Dockerfile, right?

alexcrichton · 2018-05-30T12:55:37Z

@bors: try

Indeed!

Note that this doesn't do much yet.

I'm trying to pass some additional linker args when building rustc_codegen_llvm but without any luck yet. I can't use cargo rustc because bootstrap doesn't support it (and adding support turns out to be a proper rabbit hole). Any ideas, @rust-lang/infra?

michaelwoerister · 2018-05-30T13:17:29Z

I think I'll add a custom Command type that is like std::process::Command supports "deferred" args that get added at the end just before the command is run...

@michaelwoerister It might be easier to implement the "deferred args" thing via checking the --crate-name argument passed to the rustc shim (src/bootstrap/bin/rustc.rs) and then adding the relevant args there. Not sure though.

⌛ Trying commit 55aaf63 with merge a1aeb60...

[experimental]: Build LLVM with ThinLTO enabled This is a work in progress. Let's see how it goes.

michaelwoerister · 2018-05-30T15:58:46Z

@kennytm, wait, what's going on here? https://travis-ci.org/rust-lang/rust/jobs/385738110 is still running 😕

kennytm · 2018-05-30T16:03:43Z

@michaelwoerister Huh. Probably messed up due to having too many try builds in parallel. I've canceled the latest try build, let's manually monitor Travis for now.

TimNN · 2018-07-10T17:04:46Z

Ping from triage, @michaelwoerister! Do you think you'll be able to work on this again?

michaelwoerister · 2018-07-10T17:30:13Z

I think I'll wait until #52019 is available in the bootstrap compiler. That will make things a lot nicer.

Mark-Simulacrum · 2018-07-10T17:37:33Z

Is it worth doing a (minor) beta backport to expedite this?

michaelwoerister · 2018-07-10T17:46:48Z

No, I still need to implement proper Windows support for the linker-plugin-based LTO stuff. In any case, this is not too urgent.

pietroalbini · 2018-07-23T11:42:38Z

Ping from triage @michaelwoerister! It's been a while since we heard from you, will you have time to work on this again?

pietroalbini · 2018-07-30T16:59:52Z

Thank you for this PR @michaelwoerister! Unfortunately we haven't heard from you on this in a while, so I'm closing the PR to keep things tidy. Don't worry though, if you'll have time again in the future please reopen this PR, we'll be happy to review it again!

[experimental]: Build LLVM with ThinLTO enabled (2nd attempt) This is #51207 revived. This time, I'd like to run actual performance tests to see if it improves compile times.
