# Class GolangDWARFFunctionFixup

java.lang.Object
ghidra.app.util.bin.format.golang.GolangDWARFFunctionFixup

All Implemented Interfaces:
  `DWARFFunctionFixup`, `ExtensionPoint`

public class GolangDWARFFunctionFixup extends Object implements DWARFFunctionFixup
Fixups for Go functions found during DWARF processing.

Fixes storage of parameters to match the Go callspec and modifies parameter lists to match Ghidra's capabilities.

Special characters used by Go in symbol names (middle dot ·, weird slash ∕) are fixed up in DWARFProgram.getDWARFNameInfo() by calling GoSymbolName.fixGolangSpecialSymbolnameChars().

Go's 'unique' usage of DW_TAG_subroutine_type to define its ptr-to-ptr-to-func is handled in DWARFDataTypeImporter.makeDataTypeForFunctionDefinition().
