Parsing "rand.ll"
<*>@seed = global i32 1234
define i32 @abs(i32 %x) {
0:
    %1 = icmp slt i32 %x, 0
    br i1 %1, label %2, label %4
2:
    %3 = sub i32 0, %x
    br label %5
4:
    br label %5
5:
    %.0 = phi i32 [ %3, %2 ], [ %x, %4 ]
    ret i32 %.0
}
define i32 @rand() {
0:
    %1 = load i32, i32* @seed
    %2 = mul i32 22695477, %1
    %3 = add i32 %2, 1
    store i32 %3, i32* @seed
