I don't think it actually matters, but the name is supposed to signify the 
parameters for the "instruction".  As far as I can tell:

  R - register
  L - label
  C - constant or a label that refers to a constant.

I think its basically a poor man's function overloading mechanism.  So, in
the case of prologue, it doesn't really matter since there aren't multiple
implementations of the prologue.
