[Lldb-commits] [PATCH] D32832: Make ConstString creation and access lockfree

[Scott Smith via Phabricator via lldb-commits]

scott.smith created this revision.

Utilize atomics to update linked lists without requiring locks.  Reduces the number of calls to compute the hash by not having to compute it once to determine the bucket and then again inside a separate hashtable implementation.  Use xxhash for better performance, especially with longer strings.  Eliminates calls to hash when just updating the value by being able to use atomics instead of locks.
