Is it plausible that this should happen for the other steps here? If so, we can likely achieve that by changing the macro a bit.
Currently it has:
run.builder.ensure($name {
compiler: run.builder.compiler(run.builder.top_stage, run.builder.config.build),
target: run.target,
});For "only_hosts" steps, this will run with target = host for each host already. I think then the only difference is previously we were running the dist::Rustc step always with the "build" triple compiler, whereas the new code runs it with the host triple compiler. If I understand what's going on, then the code you've added could also be something like this, and without the loop, and still work.
builder.ensure(dist::Rustc {
compiler: builder.compiler(builder.top_stage, self.target),
});
install_rustc(builder, self.compiler.stage, self.target);There was a problem hiding this comment.
Thanks for the alternate suggestion. I've verified this works and updated my commits.
although, not sure why this works - it wasn't needed before

I'm going to @bors r+ this. However, I think it would be good to try to go a bit further if you have the time with the install.rs file and try and get a framework of some kind for what the intent is behind our mix of only_hosts/target/host installs; currently it seems to be rather ad-hoc (basically each one does something a little different it looks like). I think unifying that is likely a good goal, though I'm not sure how we'd do so -- maybe inspiration from other compiler installers can be taken, or rustup itself. I don't have the time to do much more than review though :) |

rustbuild fixes
When upgrading Debian's rustc to 1.38 I needed these patches:
(1) In order to cross-compile rustc 1.38 and take it through the full rustbuild process including install, I needed the first patch.
(2) In order to build rustc 1.38 using rustc 1.38 itself I need to set --cap-lints warn, otherwise I get this error:
~~~~
error: unnecessary `unsafe` block
--> src/bootstrap/builder.rs:148:19

error: aborting due to previous error
error: could not compile `bootstrap`.
~~~~
In order to set --cap-lints warn however, I need bootstrap.py not to clobber RUSTFLAGS. (This worked previously, not sure if it was broken intentionally but we would like support for it.)
