// VE instructions have a space to hold following immediates
//   $sy has 7 bits to represent simm7, uimm7, simm7fp, or uimm7fp.
//   $sz also has 7 bits to represent mimm or mimmfp.
//   $disp has 32 bits to represent simm32.
//
// The mimm is a special immediate value of sequential bit stream of 0 or 1.
//     `(m)0`: Represents 0 sequence then 1 sequence like 0b00...0011...11,
//             where `m` is equal to the number of leading zeros.
//     `(m)1`: Represents 1 sequence then 0 sequence like 0b11...1100...00,
//             where `m` is equal to the number of leading ones.
// Each bit of mimm's 7 bits is used like below:
//     bit 6  : If `(m)0`, this bit is 1.  Otherwise, this bit is 0.
//     bit 5-0: Represents the m (0-63).
// Use `!add(m, 64)` to generates an immediate value in pattern matchings.
//
// The floating point immediate value is not something like compacted value.
// It is simple integer representation, so it works rarely.
//     e.g. 0.0 (0x00000000) or -2.0 (0xC0000000=(2)1).

//    "(, sz)", "(sy)", or "(sy, sz)".
//    AS format uses "disp", "disp(, sz)", or "(, sz)" in general.
//    AS format in RRM format uses "disp", "disp(sz)", or "(sz)".
//    AS format in RRM format for host memory access uses "sz", "(sz)",
//    or "disp(sz)".
//
// We defined them below.
//
// ASX format:
//    MEMrri, MEMrii, MEMzri, MEMzii
// AS format:
