>How-To-Repeat:
Attempt to build math/atlas port with clang 3.4 on 11.0-CURRENT i386.
>Fix:
The following patch fixes the problem for me. The MM and NN operands are
32-bit wide memory locations on stack on i386 but the patch should work
because, subq is #defined to be subl earlier in ths file for i386.
This patch is untested on amd64, but I think it should also do the right
thing because MM and NN are CPU registers.
