0c949f0a1c re PR libquadmath/81848 (Add PowerPC support to libquadmath) 
2017-09-01  Michael Meissner  <meissner@linux.vnet.ibm.com>

	PR libquadmath/81848
	* configure.ac (powerpc*-linux*): Use attribute mode KC to create
	complex __float128 on PowerPC instead of attribute mode TC.
	* quadmath.h (__complex128): Likewise.
	* configure: Regenerate.
	* math/cbrtq.c (CBRT2): Use __float128 not long double.
	(CBRT4): Likewise.
	(CBRT2I): Likewise.
	(CBRT4I): Likewise.
	* math/j0q.c (U0): Likewise.
	* math/sqrtq.c (sqrtq): Don't depend on implicit conversion
	between __float128, instead explicitly convert the __float128
	value to long double because the PowerPC does not allow __float128
	and long double in the same expression.

        * math/sqrtq.c (sqrt): NaN, INF and < 0 fixes.
        * math/expm1q.c (expm1q): Changes from GLIBC. Use expq for
        large parameters. Fix errno for boundary conditions.
        * math/finiteq.c (finiteq): Add comment.
        * math/fmaq.c (fmaq): Changes from GLIBC. Fix missing underflows
        and bad results for some subnormal results. Fix sign of inexact
        zero return. Fix sign of exact zero return.
        Ensure additions are not scheduled after fetestexcept.
        * math/jnq.c (jnq): Changes from GLIBC. Set up errno properly
        for ynq. Fix jnq precision.
        * math/nearbyintq.c (nearbyintq): Changes from GLIBC. Do not
        manipulate bits before adding and subtracting TWO112[sx].
        * math/rintq.c (rintq): Ditto.
        * math/scalbnq.c (scalbnq): Changes from GLIBC. Fix integer
