Sorry, it does not compile on gcc-4.4.1:

build/genoutput
/tmp/paludis/sys-devel-gcc-4.4.1-r1/work/gcc-4.4.1/gcc/config/i386/i386.md \
          insn-conditions.md > tmp-output.c
/tmp/paludis/sys-devel-gcc-4.4.1-r1/work/gcc-4.4.1/gcc/config/i386/i386.md:14984:
wrong number of alternatives in operand 2
