--- Comment #1 from Yuri Rumyantsev <ysrumyan at gmail dot com> ---
The cause of issue is that before ce1 phase pde (or pre) transformation has
been done to remove partial redundant moves to variable i and j, i.e.
code
int i = x;
int j = y;
if (x > y)
{
i = a;'
j = i;
}
has been transformed to
int i,j;
if (x > y)
{
i = a;
j = i;
}
else
{
i = x;
i = y;
}
and ifcvt phase does speculative motion else-part before if-part, i.e. to
original code. This transformation is considered as true change and test is
failed. I assume that test must accept also '6 basic blocks,' to get test
passed.
