position independent code

[FALE@skidata.com]

Hi,

is it possible to generate position independent code
and data references with the gnu gcc for m68k/coldfire ?

eg: 
    bsr function    instead of    jsr function
and
    mov.l var(%a5),%d0  instead of    move.l var,%d0

at the moment we use the sds crosscode c compiler
which has this option (register relative data and bss),
but can't generate code for the coldfire cpu.

I tried the -fpic and -fPIC options and got the following
assembler output

	move.l %a5,-(%sp)
	lea (%pc, _GLOBAL_OFFSET_TABLE_@GOTPC), %a5
	bsr __main@PLTPC
	"
	"
	move.l var@GOT.w(%a5),%d1
	"
	etc...

and following assembler errors
temp.s: Assembler messages:
temp.s:55: Error: parse error -- statement `lea
(%pc,_GLOBAL_OFFSET_TABLE_@GOTPC),%a5' ignored
temp.s:56: Error: parse error -- statement `bsr __main@PLTPC' ignored

seems the assembler does'nt understand the generated code ?

any ideas ?
