Thanks! I hope I'm getting things right. Specifically,
1. `UpdateIndexCallbacks::indexStdlib()::Task` in `ClangdServer.cpp`
2. `PreambleThread::run()`, `ASTWorker::run()` and
`TUScheduler::runWithPreamble()::Task` in `TUScheduler.cpp`
3. The lambda of `runAsync` in `BackgroundIndex::BackgroundIndex()` in
`index/Background.cpp`.
================
Comment at: clang-tools-extra/clangd/support/Threading.cpp:102
llvm::set_thread_name(Name);
+ // Mark the bottom of the stack for clang to be aware of the stack usage
and
+ // prevent stack overflow.

Ah, I've never noticed clangdSupport is independent of clang.

Agreed. And I think it requires an RFC before we have that migrate to
llvmSupport.
