While analyzing cases of threading through backedge.
GCC threads this case.
But does not thread this case.
int first;
void thread_backedge (void)
{
int i = 0;
do
{
if (first ==1)
{
foo ();
first=0;
}
bla ();
first =0;
} while (i++ < 100);
}
int first;
void thread_backedge (void)
{
int i = 0;
do
{
if (first ==1)
{
foo ();
first=0;
}
else
{
bla ();
first =0;
}
} while (i++ < 100);
}
