# In this test we verify that inlined functions still mention
# all their parameters in `frame variable`, even when those
# parameters were completely optimized away from the concrete
# instance of the inlined function in the debug info.
# The debugger should look up the parameters in the abstract
# origin of the concrete instance.

# Let us check that unused parameters of an inlined function are listed
# at the inlined function entry.
