22// VE instructions have a space to hold following immediates
23//   $sy has 7 bits to represent simm7, uimm7, simm7fp, or uimm7fp.
24//   $sz also has 7 bits to represent mimm or mimmfp.
25//   $disp has 32 bits to represent simm32.
26//
27// The mimm is a special immediate value of sequential bit stream of 0 or 1.
28//     `(m)0`: Represents 0 sequence then 1 sequence like 0b00...0011...11,
29//             where `m` is equal to the number of leading zeros.
30//     `(m)1`: Represents 1 sequence then 0 sequence like 0b11...1100...00,
31//             where `m` is equal to the number of leading ones.
32// Each bit of mimm's 7 bits is used like below:
33//     bit 6  : If `(m)0`, this bit is 1.  Otherwise, this bit is 0.
34//     bit 5-0: Represents the m (0-63).
35// Use `!add(m, 64)` to generates an immediate value in pattern matchings.
36//
37// The floating point immediate value is not something like compacted value.
38// It is simple integer representation, so it works rarely.
39//     e.g. 0.0 (0x00000000) or -2.0 (0xC0000000=(2)1).
