There is a simple way to get that immediate from expression you want to calculate. For example, if you want to calculate following expression:

    (NOT A) OR ((NOT B) XOR (C AND A))

then you simply write

    ~_MM_TERNLOG_A | (~_MM_TERNLOG_B ^ (_MM_TERNLOG_C & _MM_TERNLOG_A))

Literally the expression you want to calculate. It evaluates to immediate from _MM_TERNLOG_A/B/C constants defined in intrinsic headers, at least for gcc & clang:

    typedef enum {
      _MM_TERNLOG_A = 0xF0,
      _MM_TERNLOG_B = 0xCC,
      _MM_TERNLOG_C = 0xAA
    } _MM_TERNLOG_ENUM;

For MSVC you define them yourself.
