# Verify that PC-begin candidate symbols have been sorted correctly when adding
# PC-begin edges for FDEs. In this test both _main and _X are at address zero,
# however we expect to select _main over _X as _X is common. If the sorting
# fails we'll trigger an assert in EHFrameEdgeFixer, otherwise this test will
# succeed.
