Description of Operands:

rD = Destination Register (GPR or SPR)
A = Source Register (GPR or SPR) or Immediate
B = Source Register (GPR or SPR) or Immediate
M = Mask
S = Shift
E = External Condition
l = Branch label or address
lrX = Link Register (lr0 - lr3)
lrY = Link Register (lr0 - lr3)


Raw instruction format:
@bitcode_in_hexadecimal
Example: @1C0 @C11,@C22,r3


Virtual instructions are translated by the assembler to other
lowlevel instructions.
