I've now tried doing a bootstrap & regtest with --with-cpu-power6 as well,
comparing without the lra patch with after both patches.  (With master the
build hangs in the same way as it did for Zdenek.)  There didn't seem
to be any differences in test results.

Hopefully that will have given some execution test coverage when
running things like gcc.dg/dfp and c-c++-common/dfp.=
