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.
