|  | // Guidelines (in no particular order): | 
|  | // 1. Avoid relying on pattern ordering to give preference to one pattern | 
|  | //    over another, prefer using AddedComplexity instead. The reason for | 
|  | //    this is to avoid unintended conseqeuences (caused by altering the | 
|  | //    order) when making changes. The current order of patterns in this | 
|  | //    file obviously does play some role, but none of the ordering was | 
|  | //    deliberately chosen (other than to create a logical structure of | 
|  | //    this file). When making changes, adding AddedComplexity to existing | 
|  | //    patterns may be needed. | 
|  | // 2. Maintain the logical structure of the file, try to put new patterns | 
|  | //    in designated sections. | 
|  | // 3. Do not use A2_combinew instruction directly, use Combinew fragment | 
|  | //    instead. It uses REG_SEQUENCE, which is more amenable to optimizations. | 
|  | // 4. Most selection macros are based on PatFrags. For DAGs that involve | 
|  | //    SDNodes, use pf1/pf2 to convert them to PatFrags. Use common frags | 
|  | //    whenever possible (see the Definitions section). When adding new | 
|  | //    macro, try to make is general to enable reuse across sections. | 
|  | // 5. Compound instructions (e.g. Rx+Rs*Rt) are generated under the condition | 
|  | //    that the nested operation has only one use. Having it separated in case | 
|  | //    of multiple uses avoids duplication of (processor) work. | 
|  | // 6. The v4 vector instructions (64-bit) are treated as core instructions, | 
|  | //    for example, A2_vaddh is in the "arithmetic" section with A2_add. | 
|  | // 7. When adding a pattern for an instruction with a constant-extendable | 
|  | //    operand, allow all possible kinds of inputs for the immediate value | 
|  | //    (see AnyImm/anyimm and their variants in the Definitions section). | 
|  |  |
