Right now, Mozilla developers building on macOS that want to take advantage of icecream for distributed builds download environment archives from jya's Github repository at https://github.com/jyavenard/mozilla-icecream. We produce nice clang toolchains in automation; can we produce the icecream environment archives in automation as well?

jya: is there anything special about running the icecream environment creation? Does it require macOS, or can it be done from Linux (since we're cross compiling the underlying toolchain there anyway).

I want these to be produced in automation as part of Bug 1499145.

ted: if I understand the upcoming distributed sccache work, macOS (and Windows) users will need to fetch some Linux64 environment archives that are conceptually similar to the icecream environment archives. Can you confirm? These tasks would be very similar to what we'd want for that, correct?

I have never attempted to generate the toolchain archive outside the target platform. It may be possible cross-platform so long that you have a binary-O aware tool.

Can you confirm? > These tasks would be very similar to what we'd want for that, correct? You're correct. sccache-dist is using the same `icecc-create-env` script for packaging C++ compilers. For cross-compilation the configuration is slightly different, in that sccache has a config file option to tell it what Linux toolchain to use when remoting compilation. I haven't actually looked into the format of the toolchain archives, but I suspect we could just make our clang toolchain jobs upload a separate artifact that's packaged properly for this use case. Once we get people using sccache-dist we'd ideally have this all plumbed into `mach bootstrap` or something.
