208 * Loads the address of label 'name' into register 'rn'. Use this when
209 * you don't particularly need immediate instructions only, but you need
210 * the whole address in one register (e.g. it's a structure address and
211 * you want to access various offsets within it). On ppc32 this is
212 * identical to LOAD_REG_IMMEDIATE.
213 *
214 * LOAD_REG_ADDRBASE(rn, name)
215 * ADDROFF(name)
216 * LOAD_REG_ADDRBASE loads part of the address of label 'name' into
217 * register 'rn'. ADDROFF(name) returns the remainder of the address as
218 * a constant expression. ADDROFF(name) is a signed expression < 16 bits
219 * in size, so is suitable for use directly as an offset in load and store
220 * instructions. Use this when loading/storing a single word or less as:
221 * LOAD_REG_ADDRBASE(rX, name)
222 * ld rY,ADDROFF(name)(rX)
