--- Comment #5 from Martin Sebor <msebor at gcc dot gnu.org> ---
Today's trunk warns on three out of the four cases, missing just the 'if (const
bool b2 = 1)' conditional.
$ cat t.C && gcc -Wall -Wextra -Wpedantic t.C
int main()
{
bool b0 = 1; // { dg-warning "" }
const bool b00 = 1; // { dg-warning "" }
if (bool b1 = 1) // { dg-warning "" }
return 0;
else
return 1;
if (const bool b2 = 1) // { dg-warning "" }
return 0;
else
return 1;
}
t.C: In function ‘int main()’:
t.C:5:12: warning: unused variable ‘b1’ [-Wunused-variable]
if (bool b1 = 1) // { dg-warning "" }
^~
t.C:3:8: warning: unused variable ‘b0’ [-Wunused-variable]
bool b0 = 1; // { dg-warning "" }
^~
t.C:4:14: warning: unused variable ‘b00’ [-Wunused-variable]
const bool b00 = 1; // { dg-warning "" }
^~~
