From 8d7d203342f1573938e99d984ca335f05e1415bb Mon Sep 17 00:00:00 2001 From: Vedant Kumar Date: Tue, 11 Jul 2017 01:42:12 +0000 Subject: [PATCH] [llvm-cov] Disable threading in a test. NFC. PR30735 reports an issue where llvm-cov hangs with a worker thread waiting on a condition, and the main thread waiting to join() the workers. While this doesn't appear to be a bug in llvm-cov or the ThreadPool implementation, it would be helpful to disable the use of threading in the llvm-cov tests where no test coverage is added.
