ghidra.app.util.bin.format.golang.GoFunctionFixup

public class GoFunctionFixup
extends Object

Utility class that fixes golang function parameter storage using each function's current parameter list (formal info only) as starting information. TODO: verify GoFuncData.argsize property against what we calculate here

apply

public void apply()
           throws DuplicateNameException,

makeEmptyArrayDataType

public static DataType makeEmptyArrayDataType(DataType dt)

Returns a Ghidra data type that represents a zero-length array, to be used as a replacement for a zero-length array parameter.

Parameters:

dt - data type that will donate its name to the created empty array type

Returns:

DataType that represents a specific zero-length array type

reverseNonStackStorageLocations

public static void reverseNonStackStorageLocations(List<Varnode> varnodes)

Invert the order of the any register storage locations to match the decompiler's logic for assigning storage to structs that varies on endianness.

Only valid for storage scheme that has all register storages listed first / contiguous.

Parameters:

varnodes - list of varnodes that will be modified in-place
