Summary: ENTRY: Reject combining USE associated variable with
RESULT variable
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Keywords: accepts-invalid, diagnostic
Severity: normal
Priority: P3
Component: fortran
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: burnus@gcc.gnu.org
>From http://j3-fortran.org/doc/meeting/195/11-196r1.txt:
The following is invalid:
MODULE m
REAL x
CONTAINS
FUNCTION f()
f = 1
x = 2 ! <<< Use associated?
RETURN
ENTRY e() RESULT(x)
x = 3 ! <<<< Result variable?
END FUNCTION
END MODULE
Append new statement to 12.6.2.6p9 [310:23]
"A name that appears as a <result-name> in an ENTRY statement
shall not appear in the expression of a statement function that
precedes the first RESULT clause with that name unless the name is
also a dummy argument of that statement function."

Append new statement to 12.6.2.6p8 [310:20], "A name that appears as a <result-name> in an ENTRY statement shall not appear in any executable statement that precedes the first RESULT clause with that name." The part you quote concerns "statement functions". There are no statement functions in your example. ^ permalink raw reply [flat|nested] 4+ messages in thread

There are > no statement functions in your example. Well spotted. The problem also occurs in the statement function case - at least when the entry function does not set a return value - and -Wall also does not warn in that case ... FUNCTION f() x(i) = i f = x(4) ENTRY e() RESULT(x) ! x = 3 END FUNCTION ^ permalink raw reply [flat|nested] 4+ messages in thread
