I believe --jobs to x.py, so RBE's "more parallelism" benefit doesn't really exist as it stands.
On the other hand, passing --jobs=$(get_makeopts_jobs) applies that limit to both Rust's and LLVM's builds. cargo -j1000 isn't being a good citizen on machines that are also running make -j$(ncpu).
Maybe there's room for a local patch, and/or advocating upstream for --llvm-jobs, depending on whether reclient can be made to work with the rustc invocations here.
Description
Clang has ahttps://godbolt.org/z/c3P3nzn8K
diagnose_as_builtinfunction, which requests Clang to diagnose the annotated function as though it was a builtin that the user can select. e.g.,This doesn't apply for
-Wmemset-transposed-args, as youdiagnose_as_builtinshould also diagnose this case.
