I think it's actually an LLVM issue. I'm using a build of LDC 
that uses LLVM 3.4 and I don't see this issue. XMM7 and RAX are 
both valid operands for the PMOVMSKB instruction.

Okay, that would also make sense. I guess that's just one more reason 
for ditching pre-3.4 support. At this point, there is just too many 
known issues to bother with them. Especially since the LLVM 3.6 release 
is imminent, and given that even if there are no distro packages, 
compiling LLVM locally as part of building LDC is trivial.

I think the LLVM commit is 
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-
0131007/190626.html 
which was committed after 3.2. I did not check if this is 
included in LLVM 3.3 but it is in LLVM 3.4.

Thanx. I will install a more recent version of llvm alongside and 
try again.
