/*
* 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) and when 'expr' is a constant or absolute address.
*
* 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)
