Subject: [PATCH] clangd: Always link with libatomic
Trace.cpp uses atomic<double> which is not available as instrinsic
its only added in c++20, until then link with libatomic
Another solution would be to not use double atomics something like below
- std::atomic<double> EndTime; // Filled in by markEnded().
+ std::atomic<int64_t> EndTime; // Filled in by markEnded().
but I don't know if this would be just the change needed or more is
required
