@node V850 Options
@subsection V850 Options
@cindex V850 Options
These @samp{-m} options are defined for V850 implementations:
@table @code
@item -mlong-calls
@itemx -mno-long-calls
Treat all calls as being far away (near). If calls are assumed to be
far away, the compiler will always load the functions address up into a
register, and call indirect through the pointer.
@item -mno-ep
@item -mep
Do not optimize (do optimize) basic blocks that use the same index
pointer 4 or more times to copy pointer into the @code{ep} register, and
use the shorter @code{sld} and @code{sst} instructions. The @samp{-mep}
option is on by default if you optimize.
@item -mno-prolog-function
@itemx -mprolog-function
Do not use (do use) external functions to save and restore registers at
the prolog and epilog of a function. The external functions are slower,
but use less code space if more than one function saves the same number
of registers. The @samp{-mprolog-function} option is on by default if
you optimize.
@item -mspace
Try to make the code as small as possible. At present, this just turns
on the @samp{-mep} and @samp{-mprolog-function} options.
@item -mtda=@var{n}
Put static or global variables whose size is @var{n} bytes or less into
the tiny data area that register @code{ep} points to. The tiny data
area can hold up to 256 bytes in total (128 bytes for byte references).
@item -msda=@var{n}
Put static or global variables whose size is @var{n} bytes or less into
the small data area that register @code{gp} points to. The small data
area can hold up to 64 kilobytes.
@item -mzda=@var{n}
Put static or global variables whose size is @var{n} bytes or less into
the first 32 kilobytes of memory.
