Oh well. I present you, without comments, the following:

  switch (Triple.getOS()) {
  case llvm::Triple::FreeBSD:
  case llvm::Triple::NetBSD:
  case llvm::Triple::OpenBSD:
    return "i486";
  case llvm::Triple::Haiku:
    return "i586";
  default:
    // Fallback to p4.
    return "pentium4";
  }

Greetings,

Andres Freund
