__builtin_fma is now emitted as FMA_EXPR.

BTW: -ffp-contract=off didn't help to prevent this transformation.

Now that the tree code knows about FMA, the rs6000 backend needs to add
fmav4df4, fmav2df4, etc. named patterns so the vectorizer can properly
vectorize calls to fma, fmas, etc.

I don't see any powerpc/ppc-fma* failures in
http://gcc.gnu.org/ml/gcc-testresults/2010-11/msg01775.html
Has this been resolved?

this bug.
