 234  *   valid).
 235  *
 236  * LOAD_REG_ADDR(rn, name)
 237  *   Loads the address of label 'name' into register 'rn'.  Use this when
 238  *   you don't particularly need immediate instructions only, but you need
 239  *   the whole address in one register (e.g. it's a structure address and
 240  *   you want to access various offsets within it).  On ppc32 this is
 241  *   identical to LOAD_REG_IMMEDIATE.

 244  * ADDROFF(name)
 245  *   LOAD_REG_ADDRBASE loads part of the address of label 'name' into

 247  *   a constant expression.  ADDROFF(name) is a signed expression < 16 bits
 248  *   in size, so is suitable for use directly as an offset in load and store
 249  *   instructions.  Use this when loading/storing a single word or less as:
 250  *      LOAD_REG_ADDRBASE(rX, name)
 251  *      ld      rY,ADDROFF(name)(rX)
