In practice all targets that can vectorise sqrt define the appropriate
sqrt2 optab. The only case where this isn't immediately obvious
is the libmass support in rs6000.c, but Mike Meissner said that it shouldn't
be exercised for sqrt.
This patch therefore uses the internal function interface inst

The main goal of this series is to allow functions to be vectorised
simply by defining the associated optab. At the moment you can get
a scalar square root instruction by defining an md pattern like sqrtdf2.
But if you want to have vectorised sqrt, you need to have a target-

Hi Bernd,
Sorry for late reply.
The updated patch was bootstrapped on x86_64-unknown-linux-gnu and cross tested

Following changes were consulted with Martin Jambor to properly release
memory in IPA. It fixes leaks which popped up in tramp3d with -O2.
Bootstrap and regression tests have been running.
Ready after it finishes?
Thanks,
