RE: [Sdcc-user] SDCC for AVR

[Sanjiv K. G. N. <sa...@no...>]

I agree that its not complete. I also see that it generates wrong code. e.g
for code like below

	void func (unsigned char );
	main()
	{
		unsigned char i,j;
		j = !i;

		func(j);
	}

sdcc -mavr -S  generates

	_main:
        push    r2
;       test2.c 5
        movw    r30,r28
        sbiw    r30,0xfffffffe
        clr     r24
        sbiw    r30,0
        ld      r24,z
        cpse    r24,r24			==> this is wrong i suppose
        ldi     r24,1
L00003:
        mov     r2,r24
;       test2.c 7
        mov     r16,r2
        call    _func
L00001:
        pop     r2

I would strongly suggest you use avr-gcc; it's a much nicer toolchain.
