From: Mark Eggleston Date: Thu, 7 May 2020 07:02:02 +0000 (+0100) Subject: Fortran : ProcPtr function results: 'ppr@' in error message PR39695 X-Git-Tag: misc/first-auto-changelog-9~18 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7c9bfd404691e5dac7e32830ae6d9726ccf59683;p=thirdparty%2Fgcc.git Fortran : ProcPtr function results: 'ppr@' in error message PR39695 The value 'ppr@' is set in the name of result symbol, the actual name of the symbol is in the procedure name symbol pointed to by the result symbol's namespace (ns). When reporting errors for symbols that have the proc_pointer attribute check whether the result attribute is set and set the name accordingly. Backported from master. 2020-05-20 Mark Eggleston gcc/fortran/ PR fortran/39695 * resolve.c (resolve_fl_procedure): Set name depending on whether the result attribute is set. For PROCEDURE/RESULT conflict use the name in sym->ns->proc_name->name. * symbol.c (gfc_add_type): Add check for function and result attributes use sym->ns->proc_name->name if both are set. Where the symbol cannot have a type use the name in sym->ns->proc_name->name. 2020-05-20 Mark Eggleston gcc/testsuite/ PR fortran/39695 * gfortran.dg/pr39695_1.f90: New test. * gfortran.dg/pr39695_2.f90: New test. * gfortran.dg/pr39695_3.f90: New test. * gfortran.dg/pr39695_4.f90: New test.
