{aarch64,x86_64}-pc-windows-gnullvm: build host tools #140772

mati865 · 2025-05-07T21:22:32Z

This is a temporary single-release workflow to create stage0 for these targets.

I opted for bootstrapping from Linux because that's the easiest host system to work with, but once this hits beta, having dedicated Windows runners would be sensible and probably preferable.

--enable-full-tools for whatever reason doesn't seem to work when cross-compiling, because LLVM tools for the new hosts are not copied into the expected directory.

This PR changes how LLVM is built. Consider updating src/bootstrap/download-ci-llvm-stamp.

mati865 · 2025-05-11T21:12:03Z

Forgot to include try-job. Fixed it.

marcoieni · 2025-05-15T09:39:36Z

This will require MCP, but I suppose we need to know how long it takes to build first.

ok, so I guess we need to try this, right?

Unfortunately, free CI runners are not as capable as I had hoped. I've split the jobs now, but dunno if this will be acceptable.

yes, we prefer multiple free runner compared to 1 large runner 👍

Can we share the logic somehow?

Sure, I could add environment variable, configured from the Dockerfile, and use it in line 11. Then we need only a single script.

mmh so you are saying that in a few weeks you are going to open a new PR to edit this code? Why not edit it now? 🤔

Right now all *-gnullvm targets are tier 2 without host tools (they can only be used for cross compilation from another host), so they cannot host themselves because there is no host tools for them yet.
To break from this loop, we need to provide at least one cross-compiled release that contains host tools, so basically provide stage0 gnullvm host compiler. Once this happens, these targets will gain the ability to natively host themselves (on x86_64 and AArch64 Windows runners).

…=Kobzol Don't create .msi installer for gnullvm hosts WIX toolset works only on Windows hosts, but gnullvm doesn't have host toolchain yet. To get out of this loop, we will create a single release without MSI installer. Split out from: rust-lang/rust#140772

This is done now and both builds pass locally.

Also updated llvm-mingw, this release includes the final mingw-w64 v13 release instead of the pinned trunk commit (it doesn't change much but could be seen as a nice thing to use the final release).
