[PATCH] D60758: Add an assertion that parallelForEach doesn't nest.

[Rui Ueyama via Phabricator via llvm-commits]

ruiu added a comment.

If you worry about the cost of assigning a boolean value to the thread-local variable, I'd think that's really cheap and negligible. This function is not called too casually, because distributing jobs to threads waiting in the thread pool is not cheap. Compared to that, these assignments are virtually nothing.
