[PATCH] D109914: [Support] Attempt to fix deadlock in ThreadGroup

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added inline comments.


================
Comment at: llvm/lib/Support/Parallel.cpp:155
+TaskGroup::~TaskGroup() {
+  L.sync();
+  --TaskGroupInstances;
----------------
L is a member of TaskGroup. Hasn't its destructor already run `sync`?
