            Bug ID: 98202
           Summary: C++ cannot parse F128 suffix for float128 literals
           Product: gcc
           Version: 10.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: redi at gcc dot gnu.org
  Target Milestone: ---

auto f =3D __FLT128_MIN__;

<stdin>:1:10: error: unable to find numeric literal operator =E2=80=98opera=
tor""F128=E2=80=99

The macros for the F128 constants all end in a F128 suffix, which the C++
compiler doesn't understand.

Either the macros shouldn't be defined for C++ or (preferably) they should =
work
correctly. This would allow libstdc++ to define std::numeric_limits<__ieee1=
28>
