[haskell-llvm] Type of function with no arguments

[José Romildo Malaquias]

Hello.

What should be the type of an LLVM function that has no arguments and
returns an int32?

I have tried

  Function (() -> Int32)

but the llvm ir compiler does not accept it, with the error:

  llc: prog1.ll:3:18: error: void type only allowed for function results
  define i32 @main(void) {
                 ^
