Method Details

opForInt

<N1 extends Emitter.Next,
N0 extends Emitter.Ent<N1,
Types.TInt>>
Emitter<Emitter.Ent<N1,Types.TInt>> opForInt(Emitter<N0> em,
 JitType.IntJitType type)

Emit the JVM bytecode to perform the operator with int operands on the stack.

Type Parameters:

N1 - the tail of the incoming stack

N0 - the incoming stack with the input operand on top

Parameters:

em - the emitter typed with the incoming stack

type - the p-code type of the input operand

Returns:

the emitter typed with the resulting stack, i.e., the tail with the result pushed

opForLong

<N1 extends Emitter.Next,
N0 extends Emitter.Ent<N1,
Types.TLong>>
Emitter<Emitter.Ent<N1,Types.TInt>> opForLong(Emitter<N0> em,
 JitType.LongJitType type)

Emit the JVM bytecode to perform the operator with long operands on the stack.

Type Parameters:

N1 - the tail of the incoming stack

N0 - the incoming stack with the input operand on top

Parameters:

em - the emitter typed with the incoming stack

type - the p-code type of the input operand

Returns:

the emitter typed with the resulting stack, i.e., the tail with the result pushed

genRunMpInt

<THIS extends JitCompiledPassage>
Emitter<Emitter.Ent<Emitter.Bot,Types.TInt>> genRunMpInt(Emitter<Emitter.Bot> em,
 Local<Types.TRef<THIS>> localThis,
 JitCodeGenerator<THIS> gen,
 T op,
 JitType.MpIntJitType type,
 Scope scope)

Emit the JVM bytecode to perform the operator with mp-int operands.

Type Parameters:

THIS - the type of the generated passage

Parameters:

em - the emitter typed with the empty stack

localThis - a handle to the local holding the this reference

gen - the code generator

op - the p-code op

type - the p-code type of the input operand

scope - a scope for generating temporary local storage

Returns:

the emitter typed with the resulting stack, i.e., with only the result pushed

genRun

default <THIS extends JitCompiledPassage>
OpGen.OpResult genRun(Emitter<Emitter.Bot> em,
 Local<Types.TRef<THIS>> localThis,
 Local<Types.TInt> localCtxmod,
 Methods.RetReq<Types.TRef<JitCompiledPassage.EntryPoint>> retReq,
 JitCodeGenerator<THIS> gen,
 T op,
 JitControlFlowModel.JitBlock block,
 Scope scope)

Description copied from interface: OpGen

Emit bytecode into the run method.

This method must emit the code needed to load any input operands, convert them to the appropriate type, perform the actual operation, and then if applicable, store the output operand. The implementations should delegate to JitCodeGenerator.genReadToStack(Emitter, Local, JitVal, ghidra.pcode.emu.jit.analysis.JitType.SimpleJitType, Ext), JitCodeGenerator.genWriteFromStack(Emitter, Local, JitVar, ghidra.pcode.emu.jit.analysis.JitType.SimpleJitType, Ext, Scope) or similar for mp-int types.

Specified by:

genRun in interface OpGen<T extends JitUnOp>

Type Parameters:

THIS - the type of the generated passage

Parameters:

em - the emitter typed with the empty stack

localThis - a handle to the local holding the this reference

localCtxmod - a handle to the local holding ctxmod

retReq - an indication of what must be returned by this JitCompiledPassage.run(int) method.

gen - the code generator

op - the p-code op (use-def node) to translate

block - the basic block containing the p-code op

scope - a scope for generating temporary local storage

Returns:

the result of emitting the p-code op's bytecode
