--- Comment #26 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
(In reply to Andrew Pinski from comment #25)
> Note the darwin (mac OS X) aarch64 (arm64) ABI says long double is 64bits.
> It would be implemented that way even in GCC for Mac OS X ARM64.
> clang/llvm for aarch64 other than Mac OS X does support 128bit long double
> though as required by the ABI too.

PR 107315 records the adding of support of 128bit float for Darwin (as
_Float128).=
