If you have a look at avr-gcc-3.0 output then you can see

        .file   "file.c"
        .arch avr2
__SREG__ = 0x3f
__SP_H__ = 0x3e
__SP_L__ = 0x3d
__tmp_reg__ = 0
__zero_reg__ = 1
_PC_ = 2
        .text


The __zero_reg__ and the __tmp_reg__ eueal to 0 and 1 (not r0 and r1)
It's because new avr-as can understands numbers as a register names.

So, rename your `yl=r28' to `yl=28'.
