------- Comment #4 from dje at gcc dot gnu dot org 2006-01-31 21:30 -------
This was fixed by adding the 'Y' constraint to movtf_internal. One would need
to add the constraint and modify the word_offset_memref_operand() function in
rs6000.c on the GCC-3.4 branch. I am hesitant to start along that path this
late in the GCC 3.4 release cycle because changing the predicate could be much
more destabilizing. We can backport that to a distro if needed.
GCC 3.4 is not intended to build GLIBC with -mlong-double-128. GLIBC now
depends on GCC 4.1 if that option is used.
This sounds like a classic "doctor it hurts when I do this." "Then don't do
that."
