[LLVMdev] Integer divide by zero
...lowered to a single hardware instruction and avoid the branching and code bloat of manual checks on hardware where division by zero natively traps. -Joe -------------- next part -------------- An HTML attachment was scrubbed...

[LLVMdev] Integer divide by zero
I'm also not fully happy with LLVM's behavior here. There is another undefined case too, which is the minimum integer divided by -1. In Julia I can get "random" answers by doing: julia> sdiv_int(-9223372036854775808, -1) 87106304 julia> sdiv_int(-9223372036854775808, -1) 87108096 In other contexts where the arguments are not constant, this typically gives an FPE trap.
