Offload bootstrap #148671

ZuseZ4 · 2025-11-07T21:24:22Z

The recommended way to build the offload project changed.
While already at it, testing how much overhead we get from building (or shipping) the two runtimes.

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

Almost, openmp builds and offload only fails at the end, likely because defaulting to include dirs from the external (older) clang, while building the newer in-tree LLVM.

@Kobzol I got it to work:

[TIMING:end] llvm::OmpOffload { target: x86_64-unknown-linux-gnu } -- 40.429

I think that's a very reasonable tradeoff for having GPU support in nightly?

Just PGO fails, presumably because I added a new step (?)
How do I fix that?

Error: Optimized build pipeline has failed
Caused by:
    0: Cannot merge LLVM profiles
    1: No such file or directory (os error 2)

So apparently rerunning doesn't fix the profile mismatch.
Also, I was told that someone previously had tried to get pgo to work with omp/offload, but that it never fully worked. So the best thing would likely be to just fully exclude it from PGO, how can we do that?

ZuseZ4 · 2025-12-11T17:07:49Z

In the absence of better ideas, I'll do the same thing over and expect a different result.
