| // 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. | |||||
