#
# Test a series of joins, where:
# * The locations agree, although registers have changed,
# * A register down one of the predecessors has been def'd,
# * The register operands to DBG_VALUE_LIST have been swapped,
# * A spurious additional operand has been added to one path,
# * The expressions are not the same (plus -> minus).
#
# Each join block below checks for one DBG_VALUE_LIST: either we re-state the var
# location in a block for the next test, or it's created as a live-in and we
# use that for the next test. Two DBG_VALUE_LISTs in a block would represent
# a live-in that we didn't expect, and a test failure.
#
# Each conditional block should have at least one, possibly two.
