Subject: [ltt-dev] [RELEASE] Userspace RCU library 0.4.4
Date: Thu, 20 May 2010 18:16:07 -0400 [thread overview]
Message-ID: <20100520221607.GA17946@Krystal> (raw)
Hi,
The Userspace RCU library 0.4.4 (available at http://lttng.org/urcu) includes an
atomic operations fix for the 32-bit (and 64-bit) powerpc architectures, where
the 4-byte cmpxchg was using a cmpd rather than the appropriate cmpw
instruction.
It did cause illegal instruction faults on powerpc 32.
Thanks,
Mathieu
