# Tests selection for the proper FDE AddrX encoding at the boundaries
# between uint8_t, uint16_t, and uint32_t. The first FRE always fits
# anywhere, because its address-offset is zero. The last FRE
# determines the smallest AddrX it is possible to use. Align
# functions to 1024 to make it easier to interpet offsets.
