Alright, ./x.py test src/test/run-make-fulldeps now suceeds with download-ci-llvm = "if-available" if I hard-code this try build instead of this:

rust/src/bootstrap/bootstrap.py

Lines 435 to 439 in 5546335

	llvm_sha = subprocess.check_output([
	"git", "log", "--author=bors", "--format=%H", "-n1",
	"-m", "--first-parent",
	"--", "src/llvm-project"
	]).decode(sys.getdefaultencoding()).strip()

But if we land this PR as-is, that logic will still pick the last bors commit that touched the LLVM submodule which for now is before this PR and so does not have the extra tools.

[Mark-Simulacrum]

Hm, I wonder if we should just add a stamp file somewhere and check that as well in the list - I feel like that's the right call here. Would you be up for doing that?

[SimonSapin]

Sure, what would be a good location?

[Mark-Simulacrum]

Let's put it in src/bootstrap/llvm-submodule-stamp. (But I don't care strongly).

[SimonSapin]

I believe this is ready for review and landing
