I'm now working on support for TS 18661-3 _FloatN / _FloatNx type names (keywords), constant suffixes and addiitions. That will address, for C, the need to use modes for complex float128 (bug 32187) by allowing the standard _Complex _Float128 to be used. The issue would still apply for C++ (I'm not including any C++ support for these type names / constant suffixes in my patch), and for complex ibm128. -- Joseph S. Myers joseph@codesourcery.com
