The WIP TS29113 testsuite https://gcc.gnu.org/pipermail/gcc-patches/2021-July/574115.html has tests types/c535b-*.f90 for this. c535b-2 and c535b-3 are failing with several cases of missing diagnostics, or bogus errors. E.g. the latter test case focuses on the 2-argument form of the ASSOCIATED intrinsic and produces errors like Error: 'pointer' argument of 'associated' intrinsic at (1) must be of rank -1 in a context where I think assumed-rank should be allowed (first argument to an intrinsic inquiry function). ^ permalink raw reply [flat|nested] 4+ messages in thread

It was also incorrectly giving an error for calls to the 2-argument form of the ASSOCIATED intrinsic, which is supposed to be permitted by C838. 2021-09-19 Sandra Loosemore <sandra@codesourcery.com> PR fortran/101334 gcc/fortran/ * check.c (gfc_check_associated): Allow an assumed-rank array for the pointer argument. * interface.c (compare_parameter): Also give rank mismatch error on assumed-rank array. gcc/testsuite/ * gfortran.dg/c-interop/c535b-2.f90: Remove xfails. * gfortran.dg/c-interop/c535b-3.f90: Likewise. ^ permalink raw reply [flat|nested] 4+ messages in thread
