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
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.
