Hi:
Would it be possible to support interchange floating point and/or
extended floating point for C++, which is introduced by ISO/IEC TS
18661-3?
I've read the note about C++ support from the initial commit log[1],
so I know there is some concern about C++ support for that, is it
possible to enable that for C++ like a language extension for C++?
The main demand comes from the data type for half-precision, ISO/IEC
TS 18661-3 is the only common spec which supports half-precision and
both GCC and clang are supported.
However it can't be used on C++ for GCC, so it's hard to use that as a
workable solution for half-precision data types.
Or maybe ISO/IEC JTC1 SC22 WG14 N2016[2] is a better way for
half-precision data types?
See https://wg21.link/p1467 and https://wg21.link/p1467 for the
relevant C++ proposals.
Isn't that the same link two times ?
