--- Comment #5 from Martin Sebor <msebor at gcc dot gnu.org> ---
It seems like it should be trivial to enhance the warning by adding a note with
the suggestion(s) mentioned in the request.
For reference, the following is what Clang prints:
$ cat t.c && clang -S -Wparentheses t.c
int f (int a, int b)
{
if (a = b)
return 1;
return 2;
}
t.c:3:11: warning: using the result of an assignment as a condition without
parentheses [-Wparentheses]
if (a = b)
~~^~~
t.c:3:11: note: place parentheses around the assignment to silence this warning
if (a = b)
^
( )
t.c:3:11: note: use '==' to turn this assignment into an equality comparison
if (a = b)
^
==
1 warning generated.
