Constructor Detail

FDdrInstruction

public FDdrInstruction(int opcode,
                       int rd,
                       int ra,
                       Displacement disp,
                       int dftn,
                       boolean macosx)

Parameters:

opcode - is the instruction's opcode

rd - is the destination register

ra - is the source register

disp - is the displacement

dftn - specifies the loader operation on the displacement

macosx - boolean specifies macosx when true and linux when false

Method Detail

assembler

public void assembler(Assembler asm,
