[Bug rtl-optimization/33258] New: guaranteed-true arithmetic test not optimized away depending on constant

[raeburn at raeburn dot org]

As in 33257, I was playing around with division+remainder code, and found
another case gcc didn't optimize.  I was using signed and unsigned variants,
and tried a couple different constants.  The test case was optimized properly
with the constant 3 (signed or unsigned math), and with the constant 128 if
unsigned math was used.  Using 128 with signed math, the test didn't get
optimized away.
