/* rtx gen_rtx (code, mode, [element1, ..., elementn])
**
** This routine generates an RTX of the size specified by
** <code>, which is an RTX code. The RTX structure is initialized
** from the arguments <element1> through <elementn>, which are
** interpreted according to the specific RTX type's format. The
** special machine mode associated with the rtx (if any) is specified
** in <mode>.
**
** gen_rtx can be invoked in a way which resembles the lisp-like
** rtx it will generate. For example, the following rtx structure:
**
** (plus:QI (mem:QI (reg:SI 1))
** (mem:QI (plusw:SI (reg:SI 2) (reg:SI 3))))
**
** ...would be generated by the following C code:
**
** gen_rtx_PLUS (QImode,
** gen_rtx_MEM (QImode,
** gen_rtx_REG (SImode, 1)),
** gen_rtx_MEM (QImode,
** gen_rtx_PLUS (SImode,
** gen_rtx_REG (SImode, 2),
