[Trilinos-Users] [12.2.1] Amesos2 suspicious waring in AMESOS2_SLUD_GET_EQUED

[Denis Davydov]

Dear developers,

I have the following warning on Clang (AppleClang 6.1.0.6020053) which looks quite suspicious:

In file included from /usr/local/lib/cmake/Pike/../../../include/Amesos2_Superludist_decl.hpp:58:
/usr/local/lib/cmake/Pike/../../../include/Amesos2_Superludist_FunctionMap.hpp:285:17: warning: comparison of constant 67 with expression of type 'SLUD::DiagScale_t' is always false [-Wtautological-constant-out-of-range-compare]
      char eq = AMESOS2_SLUD_GET_EQUED(*equed);
                      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

                                                                                                                                                                         ~~~~^ ~~~

Could you please check if the marco makes sense on all compilers and still holds for Superlu_Dist 4.1?

Kind regards,
Denis
