Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |INVALID Status|NEW |RESOLVED --- Comment #25 from Andrew Pinski <pinskia at gcc dot gnu.org> --- 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.
