Hi David,
Please ignore this request. I had asked Paul to do this, but was
confused that it relied on other patches that are not in GCC 5. My
fault.

Hi David,
Bill merged this into trunk last week.
Is it okay to backport this to GCC 5?
Thanks,
Paul

* config/rs6000/sfp-machine.h:
(_FP_DECL_EX): Declare _fpsr as a union of u64 and double.
(FP_TRAPPING_EXCEPTIONS): Return a bitmask of trapping
exceptions.
(FP_INIT_ROUNDMODE): Read the fpscr instead of writing
a mystery value.
(FP_ROUNDMODE): Update the usage of _fpscr.
Okay.
Thanks, Dav

I have no comments on this patch beyond again suggesting that it would be
desirable for some future float128 GCC patch to enable as many as possible
of the x86 float128 tests (that is, tests of float128 anywhere in the GCC
testsuite that currently are restricted to x86, x86_64 and ia64 targets o
