|  | // AsmOperandClasses require a strict ordering which is difficult to manage | 
|  | // as a hierarchy. Instead, we use a linear ordering and impose an order that | 
|  | // is in some places arbitrary. | 
|  | // | 
|  | // Here the rules that are in use: | 
|  | // * Wider immediates are a superset of narrower immediates: | 
|  | //     uimm4 < uimm5 < uimm6 | 
|  | // * For the same bit-width, unsigned immediates are a superset of signed | 
|  | //   immediates:: | 
|  | //     simm4 < uimm4 < simm5 < uimm5 | 
|  | // * For the same upper-bound, signed immediates are a superset of unsigned | 
|  | //   immediates: | 
|  | //     uimm3 < simm4 < uimm4 < simm4 | 
|  | // * Modified immediates are a superset of ordinary immediates: | 
|  | //     uimm5 < uimm5_plus1 (1..32) < uimm5_plus32 (32..63) < uimm6 | 
|  | //   The term 'superset' starts to break down here since the uimm5_plus* classes | 
|  | //   are not true supersets of uimm5 (but they are still subsets of uimm6). | 
|  | // * 'Relaxed' immediates are supersets of the corresponding unsigned immediate. | 
|  | //     uimm16 < uimm16_relaxed | 
|  | // * The codeGen pattern type is arbitrarily ordered. | 
|  | //     uimm5 < uimm5_64, and uimm5 < vsplat_uimm5 | 
|  | //   This is entirely arbitrary. We need an ordering and what we pick is | 
|  | //   unimportant since only one is possible for a given mnemonic. |
