--- Comment #2 from Joel Sherrill <joel at gcc dot gnu.org> --- Multiple BSPs trigger this on various files which is not a surprise seeing as it is generating an illegal memory to memory move. But in case it helps, this is the list of CPU CFLAGS of BSPs which trigger it. I really believe this is a breakage for all Coldfire variants though. -mcpu=5206 -mcpu=5235 -mcpu=5272 -mcpu=528x -mcpu=52235 -mcpu=5307 -mcfv4e -Wa,-memac
