# This file is part of the GDB testsuite.  It tests reverse stepping.
# Lots of code borrowed from "step-test.exp".

#
# reverse-next over a function call sets a step-resume breakpoint at
# callee's entry point, runs to it, and then does an extra single-step
# to get at the callee's caller.  Test that a user breakpoint set at
# the same location as the step-resume breakpoint isn't ignored.
