// Contract on scratch and work registers.
// =======================================
//
// On ppc, the register set {R2..R12} is available in the interpreter as scratch/work registers.
// You should, however, keep in mind that {R3_ARG1..R10_ARG8} is the C-ABI argument register set.
// You can't rely on these registers across calls.
//
// The generators for CRC32_update and for CRC32_updateBytes use the
// scratch/work register set internally, passing the work registers
// as arguments to the MacroAssembler emitters as required.
//
// R3_ARG1..R6_ARG4 are preset to hold the incoming java arguments.
// Their contents is not constant but may change according to the requirements
// of the emitted code.
//
// All other registers from the scratch/work register set are used "internally"
// and contain garbage (i.e. unpredictable values) once blr() is reached.
// Basically, only R3_RET contains a defined value which is the function result.
