2004-04-29  Jakub Jelinek  <[e-mail]>

	* 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 <[e-mail]>.
