From 18a45e39765d394ea5f4496c0a05dca862a9ebb5 Mon Sep 17 00:00:00 2001 From: polgreen Date: Tue, 17 Oct 2017 10:17:19 +0200 Subject: [PATCH 01/13] Output lines of code in trace and values in hex format Introduces cmd line options --hex and --trace-verbosity --hex outputs all trace values in hex instead of binary setting --trace-verbosity >1 will output the corresponding line of source code with each state If numbers stop being stored as binary, this implementation will need to change, but this also applies to the binary output.
