# The unit under test is the shipping tasks/task_overlay.c, compiled
# from the tree against the real task queue and the real shared
# per-frame I/O window (tasks/task_nbio_slice.c).
#
# features_cpu.c is deliberately NOT linked: the test supplies
# cpu_features_get_time_usec() itself as a virtual clock advancing a
# fixed step per observation.  That is what makes the pacing
# assertions exact - step 0 is a window that never expires, a large
# step is one exhausted on first observation - instead of dependent
# on how fast the machine running CI happens to be.
#
# RARCH_INTERNAL stays undefined so the loader builds without the
# video driver behind it; image loading is stubbed by the test.
