insn.op
Bytecode helpers. Fns for opcodes with an underscore in their name
(e.g., IF_ICMPEQ) use a dash instead (e.g., if-icmpeq).
aconst-null

invokedynamic
(invokedynamic v mname desc boot)(invokedynamic v mname desc boot args)
Call bootstrap method `boot` to return callsite for method `mname`
with arguments and return type given by `desc`. Note that this
instruction requires version 7 bytecode and above.
The bootstrap method can be a ASM Handle (see `insn.util`) or an op
sequence of the form specified by the invokeX instructions.
An optional seq of constant arguments `args` may be given and each
must be either an Integer, Float, Long, Double, String, ASM Type, ASM
Handle, or ASM ConstantDynamic object. These are passed to the
bootstrap method.

(invokeinterface v cls mname)(invokeinterface v cls mname desc-or-arity)(invokeinterface v cls mname desc-or-arity iface)
Call method named `mname` of class `cls` with the method arguments
and return type given by `desc`.
If the type descriptor is not provided or is a numeric arity, it will
be determined through reflection. In this case, the class must be
given as a string or Class object.
The last argument `iface` can be used to specify the method's owner
class is an interface (e.g., a default implementation).
invokespecial
(invokespecial v cls mname)(invokespecial v cls mname desc-or-arity)(invokespecial v cls mname desc-or-arity iface)
Call method named `mname` of class `cls` with the method arguments
and return type given by `desc`.
If the type descriptor is not provided or is a numeric arity, it will
be determined through reflection. In this case, the class must be
given as a string or Class object.
The last argument `iface` can be used to specify the method's owner
class is an interface (e.g., a default implementation).
invokestatic
(invokestatic v cls mname)(invokestatic v cls mname desc-or-arity)(invokestatic v cls mname desc-or-arity iface)
Call method named `mname` of class `cls` with the method arguments
and return type given by `desc`.
If the type descriptor is not provided or is a numeric arity, it will
be determined through reflection. In this case, the class must be
given as a string or Class object.
The last argument `iface` can be used to specify the method's owner
class is an interface (e.g., a default implementation).
invokevirtual
(invokevirtual v cls mname)(invokevirtual v cls mname desc-or-arity)(invokevirtual v cls mname desc-or-arity iface)
Call method named `mname` of class `cls` with the method arguments
and return type given by `desc`.
If the type descriptor is not provided or is a numeric arity, it will
be determined through reflection. In this case, the class must be
given as a string or Class object.
The last argument `iface` can be used to specify the method's owner
class is an interface (e.g., a default implementation).

ConstantDynamic value `x`.
ldc2

lload

Push or write local variable at index `idx`.
local-variable
(local-variable v vname vtype start end idx)
Add a reference to a local variable `vname` of type `vtype` with
index number `idx`. The variable scope is demarcated by labels `start`
and `end`. If either label has not yet been visited (marked), an
error will be thrown.

lookupswitch*
(lookupswitch* v default tkeys tlabels)
Jump to a corresponding label given in `tlabels` by an int table
lookup of the pre-sorted `tkeys` (as per `zipmap`.) If no mapping is
found, jump to the `default` label.

Continue from address given by local variable at index `idx`.
tableswitch
(tableswitch v imin imax default labels)
Constant-time index of int table between `imin` and `imax` inclusive,
jumping to corresponding label in `labels`. If the value 'off' is not
within range, jump to the `default` label. Otherwise, jump to the
label index given by: (- (- imax imin) (- imax off))
trycatch
(trycatch v start end handler etype)
Mark region between `start` and `end` labels as protected by label
`handler` against throwable `etype`. To handle all exceptions, pass
nil as the throwable type.
