From eb069ae8819c3a84d7f78becc5501e21ee3a9554 Mon Sep 17 00:00:00 2001 From: Mark Eggleston Date: Thu, 7 May 2020 08:02:02 +0100 Subject: [PATCH] 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. 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. --- gcc/fortran/ChangeLog | 11 +++++++++++ gcc/fortran/resolve.c | 6 ++++-- gcc/fortran/symbol.c | 7 +++++-- gcc/testsuite/ChangeLog | 8 ++++++++ gcc/testsuite/gfortran.dg/pr39695_1.f90 | 8 ++++++++ gcc/testsuite/gfortran.dg/pr39695_2.f90 | 12 ++++++++++++ gcc/testsuite/gfortran.dg/pr39695_3.f90 | 11 +++++++++++ gcc/testsuite/gfortran.dg/pr39695_4.f90 | 14 ++++++++++++++ 8 files changed, 73 insertions(+), 4 deletions(-) create mode 100644 gcc/testsuite/gfortran.dg/pr39695_1.f90 create mode 100644 gcc/testsuite/gfortran.dg/pr39695_2.f90 create mode 100644 gcc/testsuite/gfortran.dg/pr39695_3.f90 create mode 100644 gcc/testsuite/gfortran.dg/pr39695_4.f90 diff --git a/gcc/fortran/ChangeLog b/gcc/fortran/ChangeLog index ab79158..fb0e47c 100644 --- a/gcc/fortran/ChangeLog +++ b/gcc/fortran/ChangeLog @@ -1,3 +1,14 @@ +2020-05-20 Mark Eggleston + + PR fortran/39695 + * resolve.c (resolve_fl_procedure): Set name depending on + whether the result attribute is set.
