| 27 | * has different conventions and we capture those here. Changing something that is callee save and |
| 28 | * making it caller save places a burden on up-calls to save/restore the callee save register, |
| 29 | * however, there are few registers that are callee save in the ABI. Changing something that is |
| 30 | * caller save and making it callee save places a burden on down-calls to save/restore the callee |
| 31 | * save register. For these reasons we aim to match native conventions for caller and callee save. |
| 32 | * On x86 only the first 4 registers can be used for byte operations, for this reason they are |
| 33 | * preferred for temporary scratch registers. |
