Bug #: 52083
Summary: Misleading warning for internal procedures with names
of intrinsic procedures
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Keywords: diagnostic
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: bur...@gcc.gnu.org
The following warning does not make much sense for internal procedures - their
interface is known by construction
The example prints:
Warning: 'fraction' declared at (1) is also the name of an intrinsic. It
can only be called via an explicit interface or if declared EXTERNAL.
Expected: Do the same as for module procedures, namely print:
Warning: 'fraction' declared at (1) may shadow the intrinsic of the same
name. In order to call the intrinsic, explicit INTRINSIC declarations
may be required.
Example:
x = fraction()
contains
function fraction()
fraction = 1./42.
end function fraction
end

One probably needs to check:
sym->ns->parent && sym->ns->parent->proc_name
&& sym->ns->parent->proc_name->attr.flavor != FL_MODULE
The current checks are done in intrinsic.c's gfc_warn_intrinsic_shadow.
