# This test tests the restoration of various kinds of machine state
|
|
# to their original values with a process record log. We will execute

# the program forward while it changes various types of data, and
|
|
# then execute it backward to see if their values get restored.
|
|
#
|
|
# The types of machine state (data) that are tested are:
|
|
# register variable
|
|
# auto variable
|
|
# function static variable
|
|
# module static variable
|
|
# module global variable
