It seems a bit weird to have target specific descriptions. AFAIK, the behavior
is the same on all the targets: it generates branches which have full
addressability (ARC, ARM, BlackFin, Epiphany, MIPS, PPC all support this
option, probably amongst other architectures). This would easily grow
unwieldily if we try to have target specific descriptions. We support at least
ARM, MIPS, PPC, and now Hexagon. Why not make the description generic,
something like:
Generate branches with extended addressability, usually via indirect jumps.
