# Test that references to in-range GOT and stub targets can be bypassed.
# The helper file contains a function that uses the GOT for _x, and this file
# contains an external call to that function. By slab allocating the JIT memory
# we can ensure that the references and targets will be in-range of one another,
# which should cause both the GOT load and stub to be bypassed.
