Thanks for the response Mukti. I think the options could be:
|-mlong-calls -mno-ep and ||-mno-prolog-function. Could please tell me
how to sepcify these options in makefile? Because I use gmake (in
Cygwin shell)
Thanks,

Can you experiment with optionmization options and -m850 and -m850e?
have a look at this too if you are looking for quick fix.

Dear Sir,
I am using gcc compiler for v850e cpu. When I use the
arrtribute: __attribute__ ((interrupt_handler)) or
__attribute__ ((interrupt); for interrupt function, say for
example
void swnmi() __attribute__ ((interrupt_handler));
void swnmi()
{
...
..
}
main()
{
..
..
}
I am getting following error messages when I compile:
main.o (.text+0xea): In function 'swnmi': undefined reference
to '__ep'
main.o (.text+0xee): In function 'swnmi': undefined reference
to '__ep'
collect2: Id returned 1 exit status
I will be grateful to you if you could help me to get rid of
these error messages. Probably I have to link some libraries?
No, __ep is a linker variable.
man page says..
(http://ftp.gnu.org/pub/pub/old-gnu/Manuals/gas-2.9.1/html_chapter/as_24.html)
This can either be set up automatically by the linker, or
specifically set by using the -defsym __ep=<value> command
line option].
Thanks,
Mukti
Many thanks,
-Vijay
