------- Comment #7 from steven at gcc dot gnu dot org 2010-07-21 21:09 -------
The SRA rewrite for GCC 4.6 probably fixes the SRA part of this bug report (at
last!).
Can someone with a powerpc box have a look?

The other issue is that the altivec builtins are not marked so we think they can clobber the what the
pointers point to.
