This prevents linker errors when referencing small data using large
offsets. In practice it is very unlikely to be a real problem but this
was fixed because other compilers do this check and it ensures the
following tests now succeed:
- gcc.dg/torture/pr60115.c
- gcc.dg/torture/pr105665.c
PR target/115650
gcc/ChangeLog:
* config/arc/arc.cc (legitimate_small_data_address_p):
Check offset size.
gcc/testsuite/ChangeLog:
* gcc.target/arc/sdata-6.c: New test.
