Update the ULM simulator
========================

Change into the directory that contains `ulm.cc` (cloned from github in the
previous session).  Then update the source code for the simulator:

---- SHELL (path=session01/ulm) ------------------------------------------------
pwd
git pull
--------------------------------------------------------------------------------

Note that this will also download or update the ULM assembler (consisting of
`ulmas_label.awk` and `ulmas_codegen.awk`).  You will need the assembler for
the next session.

If you don't get a message that the source code of `ulm.cc` was up-to-date you
need to re-compile with

---- SHELL (path=session01/ulm) ------------------------------------------------
g++ -Wall -std=c++11 -o ulm ulm.cc
--------------------------------------------------------------------------------

Exercise
========
Verify the you correctly predicted the execution of the  programs `foo1.ulm`
and `foo2.ulm`:
