Subject: use "lock cmpxchg" instead of "lock/cmpxchg"
X-Git-Tag: 2006-12-16~83
X-Git-Url: http://git.megacz.com/?a=commitdiff_plain;h=2f3c5f235bd33482e1663049d3b9f3dbe57f48c6;p=ghc-hetmet.git

I'm not sure where the latter version came from, but it apparently
doesn't generate a legal instruction on Solaris.
