commit 82d4f1a446260333ef1590f3622196e7c76e414d
Author: Guillaume Munch <g...@lyx.org>
Date: Sun Jul 31 00:42:51 2016 +0100
Replace static with thread_local when used for caching
thread_local is a per-thread static variable, so it is thread-safe and can
be
used for caching purpose.
Remove the cache for parameter lists as discussed on the list
http://mid.gmane.org/6e871431-0e87-ed2a-3e31-b63356c23...@lyx.org.
(requires gcc >= 4.8)
