Compilation of div and mod

[emilaxelsson]

*Main> icompile (div :: Data Int32 -> Data Int32 -> Data Int32)
...
void test(int32_t v0, int32_t v1, int32_t * out)
{
    (* out) = div(v0, v1);
}

Analogously for mod.

Running GCC on the generated code gives

incompatible types in assignment to type ”int32_t” from type ”div_t”
