As I understand it, _GLIBCXX_USE_DECIMAL_FLOAT should already have been undefined for this target, and so std::decimal::decimal32 etc. should not have been usable (both the header not working without that define, and the mode attributes in the header being rejected by the front end when DFP is unsupported). I.e. such defines in libsupc++ would never have been usable on this target, so I think they are something it should be safe to remove from the ABI baseline. -- Joseph S.
