From 6514093826003512254c3d575fde9e26bf1710e8 Mon Sep 17 00:00:00 2001 From: Thomas Koenig Date: Sat, 11 Jul 2020 19:16:16 +0200 Subject: Fix ICE on warning with new interface check. In the test case, there was a warning about INTENT where an EXTERNAL masked an interface in an outer scope, when the location of the symbol was not set, leading to an ICE. Two problems, two-part solution: It makes no sense to warn about INTENT for artificially generated formal argument lists, and the location should be set. gcc/fortran/ChangeLog: PR fortran/96073 * frontend-passes.c (check_externals_procedure): Add locus information for new_sym. * interface.c (gfc_check_dummy_characteristics): Do not warn about INTENT for artificially generated variables. gcc/testsuite/ChangeLog: PR fortran/96073 * gfortran.dg/interface_48.f90: New test. --- gcc/fortran/interface.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'gcc/fortran/interface.c') diff --git a/gcc/fortran/interface.c b/gcc/fortran/interface.c index 0cc504f..e518209 100644 --- a/gcc/fortran/interface.c +++ b/gcc/fortran/interface.c @@ -1343,7 +1343,8 @@ gfc_check_dummy_characteristics (gfc_symbol *s1, gfc_symbol *s2, } /* Check INTENT. */ - if (s1->attr.intent != s2->attr.intent) + if (s1->attr.intent != s2->attr.intent && !s1->attr.artificial + && !s2->attr.artificial) { snprintf (errmsg, err_len, "INTENT mismatch in argument '%s'", s1->name); -- cgit v1.1
