--- Comment #3 from Michael Meissner <meissner at gcc dot gnu.org> ---
Subversion id 245059 fixes the majority of the issues.  However, there are some
enhancements that should be added for GCC 8:

1) Add support for converting IEEE 128-bit floating point to/from char/short
data types that is similar to the support that when in for normal 32-bit and
64-bit floating point types.

2) Add a combiner pattern for converting IEEE 128-bit floating point to 32-bit
integer and storing it in memory so that the register allocator can do the
store directly from the Altivec register instead of using direct move to save
it as a GPR (since the GPR side allows more address forms for int).

3) Similarly, add a combiner pattern when converting from a 32-bit integer in
memory to IEEE 128-bit floating point to avoid having to move it through a GPR.
