--- Comment #8 from Tobias Burnus <burnus at gcc dot gnu.org> --- (In reply to Christophe Lyon from comment #7) > Excess errors: > /gcc/testsuite/gfortran.dg/gomp/declare-simd-coarray-lib.f90:8:18: Warning: > GCC does not currently support mixed size types for 'simd' functions Looking for that string, I find plenty of those in the testsuite as: * gcc/testsuite/g++.dg/gomp/pr88182.C: // { dg-warning "GCC does not currently support mixed size types for 'simd' functions" "" { target aarch64*-*-* } .-15 } * gcc/testsuite/gcc.dg/declare-simd.c: /* { dg-warning "GCC does not currently support mixed size types for 'simd' functions" "" { target { { aarch64*-*-* } && lp64 } } .-1 } */ Thus, it looks as if has to be xfailed. As you can test whether adding xfail works, can you simply add it yourself, test it and commit it then?
