From 6289830b67c6765ec9bf1a2d1b8d249b6b845411 Mon Sep 17 00:00:00 2001 From: Mark Brand Date: Fri, 7 Oct 2022 10:43:07 +0200 Subject: [PATCH] Add DisassemblerObjdump. This extracts the existing objdump-based disassembler engine used in ExploitabilityLinux into a seperate reusable class, and adds support for most common address operand formats. This is a precursor to using DisassemblerObjdump to handle address resolution for non-canonical address dereferences on amd64.
