* sysdeps/sparc/sparc64/soft-fp/qp_qtoi.c (_Qp_qtoi): Use %f31
for single precision register, add it to __asm clobbers [BZ #139].
* sysdeps/sparc/sparc64/soft-fp/qp_qtoui.c (_Qp_qtoui): Use %f31
for single precision register, add it to __asm clobbers.
* sysdeps/sparc/sparc64/soft-fp/qp_qtoux.c (_Qp_qtoux): Use fqtox
instead of fqtoi in QP_HANDLE_EXCEPTIONS.
* sysdeps/sparc/sparc64/soft-fp/qp_qtox.c (_Qp_qtox): Likewise.
Reported by M. H. VanLeeuwen <vanl@megsinet.net>.
See http://sources.redhat.com/bugzilla/show_bug.cgi?id=139
