 254  * LOAD_REG_IMMEDIATE(rn, expr)
 255  *   Loads the value of the constant expression 'expr' into register 'rn'
 256  *   using immediate instructions only.  Use this when it's important not
 257  *   to reference other data (i.e. on ppc64 when the TOC pointer is not
 258  *   valid) and when 'expr' is a constant or absolute address.
 259  *
 260  * LOAD_REG_ADDR(rn, name)
 261  *   Loads the address of label 'name' into register 'rn'.  Use this when
 262  *   you don't particularly need immediate instructions only, but you need
 263  *   the whole address in one register (e.g. it's a structure address and
 264  *   you want to access various offsets within it).  On ppc32 this is
 265  *   identical to LOAD_REG_IMMEDIATE.
 266  *
 267  * LOAD_REG_ADDRBASE(rn, name)
 268  * ADDROFF(name)
 269  *   LOAD_REG_ADDRBASE loads part of the address of label 'name' into
 270  *   register 'rn'.  ADDROFF(name) returns the remainder of the address as
 271  *   a constant expression.  ADDROFF(name) is a signed expression < 16 bits
 272  *   in size, so is suitable for use directly as an offset in load and store
