[Lldb-commits] [PATCH] D33426: Introduce new command: thread unique-stacks

[Brian Gianforcaro via Phabricator via lldb-commits]

bgianfo created this revision.

This patch introduces a new thread command "unique-stacks".
The command is based off of "thread backtrace all" but will instead
find all threads which share matching call stacks and de-duplicate
their output, listing call stack and all the threads which share it.
This is especially useful for apps which use thread/task pools
sitting around waiting for work and cause excessive duplicate output.
I needed this behavior recently when debugging a core with 700+ threads.
