|

|
||||
Call and immediate jump instructions on Nios II processors are limited to
|
||||
transferring control to addresses in the same 256MB memory segment,
|
||||
which may result in @command{ld} giving
|
||||
@samp{relocation truncated to fit} errors with very large programs.
|
||||
The command-line option @option{--relax} enables the generation of
|
||||
trampolines that can access the entire 32-bit address space for calls
|
||||
outside the normal @code{call} and @code{jmpi} address range. These
|
||||
trampolines are inserted at section boundaries, so may not themselves
|
||||
be reachable if an input section and its associated call trampolines are
|
||||
larger than 256MB.
|
||||
|
||||
The @option{--relax} option is enabled by default unless @option{-r}
|
||||
is also specified. You can disable trampoline generation by using the
|
||||
@option{--no-relax} linker option. You can also disable this optimization
|
||||
locally by using the @samp{set .noat} directive in assembly-language
|
||||
source files, as the linker-inserted trampolines use the @code{at}
|
||||
register as a temporary.
|
||||
|
||||
Note that the linker @option{--relax} option is independent of assembler
|
||||
relaxation options, and that using the GNU assembler's @option{-relax-all}
|
||||
option interferes with the linker's more selective call instruction relaxation.
