converting rtx object to the assembly instruction.

[Viktor Pobedin]

Is there a simple way to convert rtx object to the assemble 
insutruction? Ideally I would like to have function something like:
    const char *rtx2asm(rtx insn);
returning a string with the asm instruction for the insn.
Closest thing that I found is the final_scan_insn function in final.c 
but unfortunatelly it outputs the asm string to the file so it makes it 
not usefull for my purposes.

Thanks, Viktor.
