No, it is not.

I'm sorry long double doesn't seem to work on your system. If your system does
not have the appropriate long double libraries, you probably need to use the
--with-long-double-64 option to make long

status : RESOLVED FIXED <-- seems to not apply.
For the sake of showing how there really is a problem here, we can
neatly compile some trivial code and get bizarre results simply
because the platform

We are saying the same thing here.
Those same emulation routines exist elsewhere and are called _Qp_div,
_Qp_mul and _Qp_add on Solaris SPARC systems whereas those are
implemented into other places with

Dear Jakub Jelinek :
Exactly.
Yes, I think the libmpfr/libgmp seem to work perfectly here but
the real issue is that the old 970 and pre Power ISA v.2.03 spec
type hardware is a

For libquadmath you need a working __float128 support. On x86_64, i686 and
ia64 this is done through a slow software emulation in libgcc. On powerpc*,
there is either a software emulation which requires

You can use --with-cpu=power7 as well. But if you only have power8 systems, it
is better to use --with-cpu=power8. The little endian PowerPC Linux systems
have a minimum cpu base level of power8, so

Or configure the big endian compiler with VSX by default, e.g.
--with-cpu=power8 or similar.

You need powerpc64le, big-endian doesn't support __float128.

Well, current gcc 8 snapshot doesn't work :

Thank you Sir.
I think it best if I stay with the nightly/test tarball found
at https://gcc.gnu.org/pub/gcc/snapshots/LATEST-8/ and then
I won't have to fiddle with automake/reconf etc or be too

Following the instructions at https://gcc.gnu.org/wiki/GitMirror there is
no branch anywhere that claims to be a version 8 type.
Where is this ver 8 code hidden away ?

Thank you very much Sir!
So then .. where is this gcc 8 that you speak of ? Still just a
nightly test release or is there an actual tarball hidden away?
