-@item -relax-section
-Replace identified out-of-range branches with PC-relative @code{jmp}
-sequences when possible.  The generated code sequences are suitable
-for use in position-independent code, but there is a practical limit
-on the extended branch range because of the length of the sequences.
-This option is the default.
-
-@cindex @code{relax-all} command line option, Nios II
-@item -relax-all
-Replace branch instructions not determinable to be in range
-and all call instructions with @code{jmp} and @code{callr} sequences
-(respectively).  This option generates absolute relocations against the
-target symbols and is not appropriate for position-independent code.
-

-Do not replace any branches or calls.

-@item %hiadj(@var{expression})

-((@var{expression} >> 16) & 0xffff) + ((@var{expression} >> 15) & 0x01)
-@end smallexample
-
-The @code{%hiadj} relocation is intended to be used with
-the @code{addi}, @code{ld} or @code{st} instructions
-along with a @code{%lo}, in order to load a 32-bit constant.

-@cindex @code{gprel} directive, Nios II
-@item %gprel(@var{expression})
-Subtract the value of the symbol @code{_gp} from

-to have a fast small area of memory which only
-takes a 16-bit immediate to access.
