I've looked briefly at the
http://gcc.gnu.org/ml/gcc-patches/2010-08/msg00631.html
patch, it seems the UNSPEC_REDUC* is unnecessary there (only used in the
expanders ending with DONE, in that case just a list of the operands is
enough),
and I don't see any reason for the new RTL codes either (why not just use
(gt:V4SI (reg:V4SF r1) (reg:V4SF r2)) etc. in the patterns instead?).
Furthermore, the floating vs. integral operands in vcond* should now be handled
on the trunk (just supported on i386/x86_64, but there is no reason why it
can't be added for rs6000 too).
The patch unfortunately doesn't apply cleanly, am trying to resolve the rejects
now.
