[avr-gcc-list] Puzzling behaviour of rjmp in assembler

[Tom Harris]

Greetings,

Using avr-gcc 20021111, I assembled the following:

        .section .text
        .func i2c_delay_T2
i2c_delay_T2:        
        rjmp +2
        rjmp +2
        rjmp +2
        rjmp +2
        ret          
        .endfunc     

using options `-c -x assembler-with-cpp -mmcu=at90s2313`.

On dumping the output with avr-objdump , the generated code has incorrect
offsets. `rjmp -2' looks like an infinite loop. This code used to work with
an old release of avr-gcc, I could find the verion if required.

00000000 <i2c_delay_T2>:
   0:   00 c0           rjmp    .+0             ; 0x2
   2:   ff cf           rjmp    .-2             ; 0x2
   4:   fe cf           rjmp    .-4             ; 0x2
   6:   fd cf           rjmp    .-6             ; 0x2
   8:   08 95           ret

Is this a bug or what?
