It is, it's just that long double is dealt with differently from the other types, so requiring VSX for it takes a different form: > * include/experimental/bits/simd.h [__ALTIVEC__]: Require VSX > for double, long long, and 64-bit long and 64-bit long double > intrinsic types. ^^^^^^^^^^^^^^^^^^ > The message should not say "long > double" without qualifying it as "64-bit long double". How about qualifying both such messages as in this incremental patchlet: @@ -2456,11 +2456,11 @@ template <typename _Tp, size_t _Bytes> static constexpr bool _S_is_ldouble = is_same_v<_Tp, long double>; // allow _Tp == long double with -mlong-double-64 static_assert(!(_S_is_ldouble && sizeof(long double) > sizeof(double)), - "no __intrinsic_type support for long double on PPC"); + "no __intrinsic_type support for 128-bit floating point on PPC"); #ifndef __VSX__ static_assert(!(is_same_v<_Tp, double> || (_S_is_ldouble && sizeof(long double) == sizeof(double))), - "no __intrinsic_type support for [long] double on PPC w/o VSX"); + "no __intrinsic_type support for 64-bit floating point on PPC w/o VSX"); #endif using type = typename __intrinsic_type_impl< > Okay for trunk without this part of the patch, and the spaces after the > hash signs deleted.

Thanks, awaiting feedback on the suggestion above to post the consolidated patch. -- Alexandre Oliva, happy hacker https://FSFLA.org/blogs/lxo/ Free Software Activist GNU Toolchain Engineer Disinformation flourishes because many people care deeply about injustice but very few check the facts.
