Class DecoderForOnePassage

java.lang.Object

ghidra.pcode.emu.jit.decode.DecoderForOnePassage

public class DecoderForOnePassage
extends Object

The decoder for a single passage

This is a sort of "mutable" passage or passage "builder" that is used while the passage is being decoded. Once complete, this provides an immutable decoded JitPassage.

-ghidra.pcode.exec.PcodeUseropLibrary<java.lang.Object> library()

+ghidra.pcode.exec.PcodeUseropLibrary<ghidra.pcode.emu.jit.folding.MaskedBytes> library()

Get the decoder-wrapped userop library

Returns:

the library

checkSameInline

public boolean checkSameInline(PcodeOp op,
 List<PcodeOp> revalidated)

Check if the given op was replaced with the same program as before

Parameters:

op - the inlined op

revalidated - the newly-observed replacement

Returns:

true if the replacement observed during decode is the same as the one given
