Yes, I believe so, I'll see what I can do here. claim
Please ping me once you open the PR ( is taking a break :) )
The core issue is the recursion cycle handling... It focuses only on s and wasn't anticipating targets that differ only in generic type args. I believe I see the tweak we'll need here, so I should have a PR in the next day or so.

Oops, yes.
Can anyone comment on what the correct fix for this might be? I notice that if I copy and from into then I'm able to run via the linked toolchain. I initially considered changing rustup to add to the PATH, but that seems incorrect as we would be adding something outside of the toolchain root to PATH. So should x.py copy or move the binaries from into ? I'm willing to (attempt to) do the work if we can agree on what the correct fix is.
I'm not really knowledgeable about . You might want to ask in on Zulip.
Yes, it should copy the binaries from stage1-tools-bin to stage1/bin.
Mentoring instructions: Add a new argument to the macro that says whether the tool should be to the sysroot, then copy it into the sysroot just after
I believe this will be fixed by , once we figure out some problems with clippy/fmt builds.

Duplicate to and related heavily to others. But this has a nice minimal repro, so worth leaving open. Probably fixed by .
I've tested this locally and I can confirm that fixes this (with this change: ).
