--- Comment #3 from Jacob Lifshay <programmerjake at gmail.com> ---
I rewrote int_fp_mv_reduced_insn_count and merged the changes into int_fp_mv,
so  I'm marking this resolved. we can mostly copy sections into the RFC, I
already did the hard work of writing the full pseudo-code and stuff (if anyone
spots any bugs, do let me know!).
