| | | | | | | | | | | | | | | | | | | | | | | | | [Parallel] Revert sequential task changes https://reviews.llvm.org/D148728 introduced `bool Sequential` to unify `execute` and the old `spawn` without argument. However, sequential tasks might be executed by any worker thread (non-deterministic), leading to non-determinism output for ld.lld -z nocombreloc (see https://reviews.llvm.org/D133003). In addition, the extra member variables have overhead. This sequential task has only been used for lld parallel relocation scanning. This patch restores the behavior before https://reviews.llvm.org/D148728 . Fix #105958 Pull Request: https://github.com/llvm/llvm-project/pull/109084 This fixes the non-reproducibility we had noticed when linking our EFI loaders, and for which we committed a workaround in f5ce3f4ef562.

* llvm: Support: don't block signals around close if it can be avoidedMateusz Guzik2023-12-291-0/+20
| | | | | | | | | | | | | | | Signal blocking originally showed up in 51c2afc4b65b2782 ("Support: Don't call close again if we get EINTR"), but it was overzealous -- there are systems where the error is known to be fine. This commit elides signal blocking for said systems (the list is incomplete though). Note close() can still fail for other reasons (like ENOSPC), in which case an error will be returned while the fd slot is cleared up.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Implement computeHostNumHardwareThreads() for FreeBSD This retrieves CPU affinity via FreeBSD's cpuset(2) API, and makes LLVM respect affinity settings configured by the user via the cpuset(1) command. In particular, this allows to reduce the number of threads used on machines with high core counts, which can interact badly with parallelized build systems. This is particularly noticable with lld, which spawns lots of threads even for linking e.g. hello_world! This fix is related to PR48193, but does not adress the more fundamental problem, which is that LLVM by default grabs as many CPUs and/or threads as possible.
