[LLVMdev] Strange SetCond Behavior

[Reid Spencer]

Bug 337 has been filed.

Here's the simplest test case I could find that reproduces the bug:

> %global_long_1 = linkonce global long 7
> %global_long_2 = linkonce global long 49
>

> declare void %exit(int)

> int %main() {
>         %long_1 = getelementptr long* %global_long_1, long 0
>         %long_2 = getelementptr long* %global_long_2, long 0
>

>         %cond = setle long %l1, %l2
>         %cast2 = cast bool %cond to int
