/* 
 * LOAD_REG_IMMEDIATE(rn, expr)
 *   Loads the value of the constant expression 'expr' into register 'rn'
 *   using immediate instructions only.  Use this when it's important not
 *   to reference other data (i.e. on ppc64 when the TOC pointer is not
 *   valid).
 *
 * LOAD_REG_ADDR(rn, name)
 *   Loads the address of label 'name' into register 'rn'.  Use this when
 *   you don't particularly need immediate instructions only, but you need
 *   the whole address in one register (e.g. it's a structure address and
 *   you want to access various offsets within it).  On ppc32 this is
 *   identical to LOAD_REG_IMMEDIATE.
 *
 * LOAD_REG_ADDRBASE(rn, name)
 * ADDROFF(name)
 *   LOAD_REG_ADDRBASE loads part of the address of label 'name' into
 *   register 'rn'.  ADDROFF(name) returns the remainder of the address as
 *   a constant expression.  ADDROFF(name) is a signed expression < 16 bits
 *   in size, so is suitable for use directly as an offset in load and store
 *   instructions.  Use this when loading/storing a single word or less as:
 *      LOAD_REG_ADDRBASE(rX, name)
 *      ld	rY,ADDROFF(name)(rX)
