Method Details

stepOp

public void stepOp(PcodeOp op,
 PcodeFrame frame,
 PcodeUseropLibrary<MaskedBytes> library)

Description copied from class: PcodeExecutor

Step one p-code op

Overrides:

stepOp in class PcodeExecutor<MaskedBytes>

Parameters:

op - the op

frame - the current frame

library - the library, invoked in case of PcodeOp.CALLOTHER

doExecuteBranch

protected void doExecuteBranch(PcodeOp op,
 PcodeFrame frame)

Description copied from class: PcodeExecutor

Perform the actual logic of a branch p-code op

This is a separate method, so that overriding PcodeExecutor.executeBranch(PcodeOp, PcodeFrame) does not implicitly modify PcodeExecutor.executeConditionalBranch(PcodeOp, PcodeFrame).

Overrides:

doExecuteBranch in class PcodeExecutor<MaskedBytes>

Parameters:

op - the op

frame - the frame

executeBranch

public void executeBranch(PcodeOp op,
 PcodeFrame frame)

Description copied from class: PcodeExecutor

Execute a branch

This merely defers to PcodeExecutor.doExecuteBranch(PcodeOp, PcodeFrame). To instrument the operation, override this. To modify or instrument branching in general, override PcodeExecutor.doExecuteBranch(PcodeOp, PcodeFrame), PcodeExecutor.branchToOffset(PcodeOp, Object, PcodeFrame), and/or PcodeExecutor.branchToAddress(PcodeOp, Address).

Overrides:

executeBranch in class PcodeExecutor<MaskedBytes>

Parameters:

op - the op

frame - the frame

executeCall

public void executeCall(PcodeOp op,
 PcodeFrame frame,
 PcodeUseropLibrary<MaskedBytes> library)

Description copied from class: PcodeExecutor

Execute a call

Overrides:

executeCall in class PcodeExecutor<MaskedBytes>

Parameters:

op - the op

frame - the frame

library - the userop library

executeConditionalBranch

public void executeConditionalBranch(PcodeOp op,
 PcodeFrame frame)

Description copied from class: PcodeExecutor

Execute a conditional branch

Overrides:

executeConditionalBranch in class FoldingExecutor

Parameters:

op - the op

frame - the frame

doExecuteIndirectBranch

protected void doExecuteIndirectBranch(PcodeOp op,
 PcodeFrame frame)

Description copied from class: PcodeExecutor

Perform the actual logic of an indirect branch p-code op

This is a separate method, so that overriding PcodeExecutor.executeIndirectBranch(PcodeOp, PcodeFrame) does not implicitly modify PcodeExecutor.executeIndirectCall(PcodeOp, PcodeFrame) and PcodeExecutor.executeReturn(PcodeOp, PcodeFrame).

Overrides:

doExecuteIndirectBranch in class PcodeExecutor<MaskedBytes>

Parameters:

op - the op

frame - the frame

executeCallother

public void executeCallother(PcodeOp op,
 PcodeFrame frame,
 PcodeUseropLibrary<MaskedBytes> library)

Description copied from class: PcodeExecutor

Execute a userop call

Overrides:

executeCallother in class FoldingExecutor

Parameters:

op - the op

frame - the frame

library - the library of userops

onMissingUseropDef

protected void onMissingUseropDef(PcodeOp op,
 PcodeFrame frame,
 String opName,
 PcodeUseropLibrary<MaskedBytes> library)

Description copied from class: PcodeExecutor

Extension point: Behavior when a userop definition was not found in the library

The default behavior is to throw a SleighLinkException.

Overrides:

onMissingUseropDef in class PcodeExecutor<MaskedBytes>

Parameters:

op - the op

frame - the frame

opName - the name of the p-code userop

library - the library
