optimizeMinimizeRegisters	back to summary
private static RopMethod optimizeMinimizeRegisters(RopMethod rmeth, int paramWidth, boolean isStatic, EnumSet<Optimizer.OptionalStep> steps) Runs the optimizer with a strategy to minimize the number of rop-form registers used by the end result. Dex bytecode does not have instruction forms that take register numbers larger than 15 for all instructions. If we've produced a method that uses more than 16 registers, try again with a different strategy to see if we can get under the bar. The end result will be much more efficient. Parameters rmeth:RopMethod method to process paramWidth:int the total width, in register-units, of this method's parameters isStatic:boolean true if this method has no 'this' pointer argument. steps:EnumSet<Optimizer.OptionalStep> set of optional optimization steps to run Returns:RopMethod optimized method
