compiler-rt, v4.0: arm\udivsi3.S broken for division by zero
Hello,
I think the current implementation for the call "bl __aeabi_idiv0" in
builtins\arm\udivsi3.S is broken.
At least for the case that __aeabi_idiv0 returns. (the provided
implementation does)
Since LR is not preserved, the following JMP(lr) results in an endless loop.
Or is this an intentional change of the behavior?
