Subject: [Patch v2 2/3] MdePkg/BaseSynchronizationLib: Add volatile Interlocked*() APIs
Date: Thu, 17 Nov 2016 11:34:41 -0800 [thread overview]
Message-ID: <1479411282-10996-3-git-send-email-michael.d.kinney@intel.com> (raw)
In-Reply-To: <1479411282-10996-1-git-send-email-michael.d.kinney@intel.com>
The SpinLock functions in the SynchronicationLib use volatile
parameters to keep compiler from optimizing these functions
too much. The volatile keyword is missing from the Interlocked*()
functions in this same library instance. Update the library instance
to consistently use volatile on all functions in the
SynchronizationLib class.
