| // 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). |
| |
