# Test Machine interface (MI) operations
|
|
# Verify that, using the MI, we can run a simple program in both forward
|
|
# and reverse directions with the following execution commands:
|
|
# - exec-continue
|
|
# - exec-finish
|
|
# - exec-next
|
|
# - exec-step
|
|
# - exec-next-instruction
|
|
# - exec-step-instruction
|
|
|
|
# The goal is not to test gdb functionality, which is done by other tests,
|
|
# but to verify the correct output response to MI operations.
