NAME
Parrot::Op
SYNOPSIS
use Parrot::Op;DESCRIPTION
Represents a Parrot operation (op, for short).
arg_type
Returns a particular argument type.
arg_types
Returns the entire argument type list.
body =head2 body BODY
Sets or returns the op's code body. If no BODY is given, the body is returned. If BODY is given, then the body is set.
full_body
For manual ops, full_body is the same as body. For auto ops, full_body adds a final {{+=S}} line to the code to represent the auto-computed return value (S is the op size).
full_name
For argumentless ops, it's the same as name. For ops with arguments, an underscore followed by underscore-separated argument types are appended to the name.
func_name
The same as full_name, but with "Parrot_" prefixed.
name
The (short or root) name of the op.
new TYPE, NAME, ARG_TYPE_LIST
Allocates a new bodyless op. A body must be provided eventually for the op to be usable. See body.
source RET_ABS_SUB RET_REL_SUB ARG_SUB RES_SUB
Returns the full_body of the op with substitutions made for the PC-modifying and argument-access placeholders.
type
The type of the op, 'auto' or 'manual'. Manual ops are responsible for having explicit next-op RETURNs, while Auto ops can count on an automatically generated next-op to be appended. See also full_body.
