This makes it possible to format _Float32, _Float64 etc. in C++20 mode. Previously it was only possible to format them in C++23 when the <stdfloat> typedefs and the std::to_chars overloads were defined. Instead of relying on std::to_chars for those types, we can just reuse the formatters for float, double and long double. This also avoids template bloat by reusing the same specializations instead of instantiating __formatter_fp for every different type. libstdc++-v3/ChangeLog: * include/std/format (formatter): Add partial specializations for extended floating-point types. * testsuite/std/format/functions/format.cc: Move test_float128() to ... * testsuite/std/format/formatter/ext_float.cc: New test. |
