I don't know how much better the generated code for
the following would be, but at least the C code is
more compact:

unsigned char PORTB_temp;

PORTB_temp=0;
PORTB_temp|=ADRESH>0;
PORTB_temp|=(ADRESH>=31) << 1;
PORTB_temp|=(ADRESH>=62) << 2;
PORTB_temp|=(ADRESH>=93) << 3;
PORTB_temp|=(ADRESH>=124) << 4;
PORTB_temp|=(ADRESH>=155) << 5;
PORTB_temp|=(ADRESH>=186) << 6;
PORTB_temp|=(ADRESH>=217) << 7;

PORTB = PORTB_temp;
