Running c2rust_transpile::transpile
in parallel (with a .par_map
) on completely separate compilation databases (the directories under tests/
) actually causes panics regularly, and once I got a segfault, too. I'm guessing there's something in c2rust-ast-exporter
or clang
APIs that's stateful and causing lots of issues. This would be very nice to have, even if just for speeding up tests.
clang does keep internal global state, and I don't think that's going to be fixable. I think this will need to be process parallelization, i.e. what build systems do.
Yeah, that seems a lot safer to do. Would it be possible to process-parallelize the clang
and c2rust-ast-exporter
parts up until serialization, and then from deserialization on, which is all in Rust, do normal thread-parallelization?
We should be able to easily transpile all translation units in parallel, either in separate processes or threads. Just needs to be implemented at some point.
