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.

Miller <davem@davemloft.net> Ulrich Drepper <drepper@redhat.com> Marek Polacek <polacek@redhat.com>: Petr Baudis <pasky@suse.cz> * math/complex.c (csqrtq): NaN and INF fixes. * 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 overflow. Co-Authored-By: David S.
