/* The functions below are for recognizing and decoding S/390
instructions of various formats. Each of them checks whether INSN
is an instruction of the given format, with the specified opcodes.
If it is, it sets the remaining arguments to the values of the
instruction's fields, and returns a non-zero value; otherwise, it
returns zero.
These functions' arguments appear in the order they appear in the
instruction, not in the machine-language form. So, opcodes always
come first, even though they're sometimes scattered around the
instructions. And displacements appear before base and extension
registers, as they do in the assembly syntax, not at the end, as
they do in the machine language. */

place to be passed to a function, as specified by the "GNU/Linux

SP is the current stack pointer. We must put arguments, links,
padding, etc. whereever they belong, and return the new stack
pointer value.
If STRUCT_RETURN is non-zero, then the function we're calling is
going to return a structure by value; STRUCT_ADDR is the address of
a block we've allocated for it on the stack.
Our caller has taken care of any type promotions needed to satisfy
prototypes or the old K&R argument-passing rules. */
