207 * Loads the address of label 'name' into register 'rn'. Use this when
208 * you don't particularly need immediate instructions only, but you need
209 * the whole address in one register (e.g. it's a structure address and
210 * you want to access various offsets within it). On ppc32 this is
211 * identical to LOAD_REG_IMMEDIATE.
212 *
213 * LOAD_REG_ADDRBASE(rn, name)
214 * ADDROFF(name)
215 * LOAD_REG_ADDRBASE loads part of the address of label 'name' into

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