Method Details

genLoadToBool

default <N extends Emitter.Next>
Emitter<Emitter.Ent<N,Types.TInt>> genLoadToBool(Emitter<N> em,
 JitCodeGenerator<?> gen)

Description copied from interface: VarHandler

Emit bytecode to load the varnode's value, interpreted as a boolean, as an integer onto the JVM stack.

Specified by:

genLoadToBool in interface VarHandler

Type Parameters:

N - the incoming stack

Parameters:

em - the emitter typed with the incoming stack

gen - the code generator

Returns:

the emitter typed with the resulting stack, i.e., having the int boolean pushed onto it

genStoreFromStack

default <FT extends Types.BPrim<?>,
FJT extends JitType.SimpleJitType<FT,
FJT>,
N1 extends Emitter.Next,
N0 extends Emitter.Ent<N1,
FT>>
Emitter<N1> genStoreFromStack(Emitter<N0> em,
 JitCodeGenerator<?> gen,
 FJT type,
 Opnd.Ext ext,
 Scope scope)

Description copied from interface: VarHandler

Emit bytecode to store a value into a variable from the JVM stack.

Specified by:

genStoreFromStack in interface VarHandler

Type Parameters:

FT - the JVM type of the value on the stack

FJT - the p-code type of the value on the stack

N1 - the tail of the incoming stack

N0 - the incoming stack having the value to store on top

Parameters:

em - the emitter typed with the incoming stack

gen - the code generator

type - the p-code type of the value on the stack

ext - the kind of extension to apply

scope - a scope for generating temporary local storage

Returns:

the emitter typed with the resulting stack, i.e., having popped the value
