Andrew, My proposal is supposed not limited to i386/x86_64. Would do please spend some time review it and see if it can really solve problem in PowerPC? Your comments is welcome.

I have an use case for the PowerPC side of the Cell BE for variables greater than the normal stack boundary alignment of 16bytes. They need to be 128byte aligned for DMA transfering to the SPUs. I already proposed a patch [1] to fix this use case but I have not seen many replies yet. Thanks, Andrew Pinski [1] http://gcc.gnu.org/ml/gcc-patches/2007-05/msg01167.html
