Greetings, and thanks for your reply. That works! A few questions:
1) Any complex support yet?
2) Does altivec have any double precision support, a la SSE2
2.5) Any l2/l1 code?
3) Have you successfully build the full lib using this?
4) The gcc/as situation is indeed bad. I've confirmed that the latest
standard binutils can't assemble these instructions yet. Therefore, to
build on Debian, at least the patched binutils needs to be packaged
and accepted as an option for powerpc before atlas can be built there
with this kernel.
