I'm not what the means are bump the priority on this as a significant
regression in gcc4.4 as code that was building with gcc4.3 no longer builds
because the size of the generated binaries is significantly larger without
load/store multiple or out of line save/restore functions.
u-boot (an open source bootloader used on a large # of embedded PPC platforms
no longer builds with gcc4.4)
