--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I'm not sure what you are complaining about - I see two returns with 64bit code
generation as well. The code is vectorized and the epilogue is completely
peeled. Are you complaining about code size here and thus the appearant
missed cross-jumping of the epilogue? I think epilogue emission happens
too late for this.
GCC 4.7 is the last with vectorization and a single return point but it
also doesn't peel the epilogue (4.8 does).
