Subject: [PATCH] libquadmath: Fix up libquadmath/math/sqrtq.c compilation in
some powerpc* configurations [PR116007]
My PR114623 change started using soft-fp.h and quad.h for the sqrtq implementation.
Unfortunately, that seems to fail building in some powerpc* configurations, where
TFmode isn't available.
quad.h has:
#ifndef TFtype
typedef float TFtype __attribute__ ((mode (TF)));
#endif
and uses TFtype. quad.h has:
/* Define the complex type corresponding to __float128
("_Complex __float128" is not allowed) */
#if (!defined(_ARCH_PPC)) || defined(__LONG_DOUBLE_IEEE128__)
typedef _Complex float __attribute__((mode(TC))) __complex128;
#else
typedef _Complex float __attribute__((mode(KC))) __complex128;
#endif
with the conditional and KCmode use added during porting of libquadmath
to powerpc*, so I've just defined TFtype for powerpc when __LONG_DOUBLE_IEEE128__
isn't defined; I could define it to float __attribute__ ((mode (KF))) but it
seemed easier to just define it to __float128 which should do the same thing.

* math/sqrtq.c (TFtype): For PowerPC without __LONG_DOUBLE_IEEE128__
define to __float128 before including soft-fp.h and quad.h.
