clang already supports _Float16 on C++ for a while, but only very few targets, ARM, AArch64, SPIR and AMDGPU. > That's documented at > http://itanium-cxx-abi.github.io/cxx-abi/abi.html#mangling-builtin Seems like it is already defined for _FloatN types, and clang already follow that. ::= DF <number> _ # ISO/IEC TS 18661 binary floating point type _FloatN (N bits) Thank you, Jonathan, I'll start to add that to C++ :)
