--- Comment #30 from Jim Wilson <wilson at gcc dot gnu.org> --- Looking at your v2 patch, the first verison fails because you are passing mismatched modes to emit_move_insn. The version with gen_lowpart solves that problem, but fails because of infinite recursion. The v4 patch looks good. There are some coding style issues, but I can always fix them for you. There should be a space before open paren. The first && should line up with the last two. The braces should be indented two more spaces. The comment needs to end with a period and two spaces. In the comment, instead of "Separate ... to ..." I'd say "Expand ... to ..." or maybe "Emit ... as ...". Now we need the copyright assignment paperwork.
