On:
int a[18];
void
foo (void)
{
int i;
for (i = 16; i < 32; i++)
a[i] = 26;
}
distilled from unwind-dw2.c, I'm just surprised that at -O2
the http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53265#c15
debugging hack reports that we are in some cases increasing the number of
iterations from 2 to 16, but later on from 1 to 15? Have we peeled one
iteration or what happened?
