@ Tests for group relocations.
@
@ Beware when editing this file: it is carefully crafted so that
@ specific PC- and SB-relative offsets arise.
@
@ Note that the gas tests have already checked that group relocations are
@ handled in the same way for local and external symbols.

@ We will place .text at 0x8000.
