[Sdcc-user] Peep hole optimizations of ld

[Sebastian Riedel]

Is it possible to compare a %-variable with the current value of a 
register? I currently don't see a way to do that.

That would allow me to optimize
        xor     a, a
        ld      (bc), a
        ld      a, #0x01
to
        xor     a, a
        ld      (bc), a
        inc     a
etc. with just one rule.
