setInterpDir()

void Loader::setInterpDir

(

const std::string &

This is the interface for setting up a base path for the elf interpreter.

This is needed when loading a cross-compiled (guest ISA != host ISA) dynamically linked application.

Parameters

dirname

base path for the interpreter

Variable Documentation

debugSymbolTable

SymbolTable Loader::debugSymbolTable

Global unified debugging symbol table (for target).

Conceptually there should be one of these per System object for full system, and per Process object for non-full-system, but so far one big global one has worked well enough.
