I can confirm this bug on mainline with this testcase:
------------------------------------------------------------------------------
void abort (void);
int f ()
{
return 0;
}
void __attribute__((noinline)) g (int k, int l)
{
int j;
if (f ())
{
j = k + l;
}
else
{
j = k + l + 1;
if (j > 0)
j++;
else
if (j < 0)
j--;
}
if (j % 2 != 0)
abort ();
}
int main ()
{
g (-2, 0);
return 0;
}
