            Bug ID: 110471
           Summary: d: Don't generate code that throws exceptions when
                    compiling with `-fno-exceptions'
           Product: gcc
           Version: 9.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: d
          Assignee: ibuclaw at gdcproject dot org
          Reporter: ibuclaw at gcc dot gnu.org
  Target Milestone: ---

The predefined version conditions D_ModuleInfo, D_Exceptions, and D_TypeInfo
were added in r9-7112.  However individual feature flags do not turn off th=
ese
versions.

For example. this should succeed compilation.

// { dg-options "-fno-exceptions" }
version (D_Exceptions)
    static assert(false);  // expected to never trigger.=
