--- Comment #8 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Good news, with GCC 6's new -Wmisleading-indentation flag we emit the
appropriate warning for the test case in comment #1:
62184.C: In function ‘int foo()’:
62184.C:5:3: warning: this ‘while’ clause does not guard...
[-Wmisleading-indentation]
while (bar());
^~~~~
62184.C:6:5: note: ...this statement, but the latter is misleadingly indented
as if it is guarded by the ‘while’
sleep();
^~~~~
As for the test case in comment #6:
int main()
{
for (; 1<2; );
if (1==1);
while (1==1);
return 0;
}
We don't and arguably shouldn't warn, because none of the statements are
indented as if they're intended to be guarded by a previous one. However, we
do warn (twice) for
int main()
{
for (; 1<2; );
if (1==1);
while (1==1);
return 0;
}
So I think this PR can finally be closed.
