Method Details

swapMarkup

public void swapMarkup(ParameterPieces op)

Swap data-type markup between this and another parameter Swap any data-type and flags, but leave the storage address intact. This assumes the two parameters are the same size.

Parameters:

op - is the other parameter to swap with this.

getVariableStorage

public VariableStorage getVariableStorage(Program program)

mergeSequence

public static ArrayList<Varnode> mergeSequence(ArrayList<Varnode> seq,
 Language language)

Assuming the given list of Varnodes go from most significant to least significant, merge any contiguous elements in the list. Merges in a register space are only allowed if the bigger Varnode exists as a formal register.

Parameters:

seq - is the given list of Varnodes

language - is the Language associated with the calling convention.

Returns:

the merged list (which may be the original list)

assignAddressFromPieces

public void assignAddressFromPieces(ArrayList<Varnode> pieces,
 boolean mostToLeast,
 boolean onePieceJoin,
 Language language)

Generate a parameter address given the list of Varnodes making up the parameter.

Parameters:

pieces - is the given list of Varnodes

mostToLeast - is true if the list is ordered most significant to least

onePieceJoin - is true if the address should be considered a join of one piece

language - is the Language associated with the calling convention
