- 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.

- PR target/116007
- * math/sqrtq.c (TFtype): For PowerPC without __LONG_DOUBLE_IEEE128__
- define to __float128 before including soft-fp.h and quad.h.
