|
// 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).
|
