| // SkJumper_stages.cpp has some unusual constraints on what constants it can use. |
| // |
| // If the constant is baked into the instruction, that's ok. |
| // If the constant is synthesized through code, that's ok. |
| // If the constant is loaded from memory, that's no good. |
| // |
| // We offer a couple facilities to get at any other constants you need: |
| // - the C() function usually constrains constants to be directly baked into an instruction; or |
| // - the _i and _f user-defined literal operators call C() for you in a prettier way; or |
| // - you can load values from this struct. |
