Ping? (The false positives are technically regressions. I didn't file a separate PR, though).
what it says in the ChangeLog entry. This fixes a few false positives. Regression-tested. OK for trunk? Best regards Thomas Mark variables in references for variable definition context as used. Code like "a(i) = 42" would not mark i as used, leading to false positives for warnings with -Wunused-but-set-variable. This is fixed in the attached patch. It also removes some default arguments to make sure that the caller side provides correct information. gcc/fortran/ChangeLog: PR fortran/30438 * gfortran.h (gfc_value_set_at): Remove default argument. (gfc_expr_set_at): Add prototype. * interface.cc (gfc_compare_actual_formal): Use gfc_expr_set_at. * intrinsic.cc (mark_args_as_used): Likewise. * io.cc (resolve_tag): Likewise. (gfc_resolve_dt): Likewise. (gfc_resolve_inquire): Likewise. * resolve.cc (resolve_transfer): Likewise. (mark_lhs_assignments_set): Likewise. * symbol.cc (gfc_lvalue_allocated_at): Add comment, fix formatting. (gfc_expr_set_at): New fuction. gcc/testsuite/ChangeLog: PR fortran/30438 * gfortran.dg/warn_unused_but_set_variable_2.f90: New test.
