Summary: constant expression 1+1 --> 2L ?

Initial Comment:
Programm: 
 
unsigned char foo1 (unsigned char c) 
{ 
    return c == 1+1 ? 10 : 20; 
} 
 
unsigned char foo2 (unsigned char c) 
{ 
    return c == 2 ? 10 : 20; 
} 
 
Result foo1: 
	... 
;ipi.c:3: return c == 1+1 ? 10 : 20; 
;     genCast 
        mov     r3,#0x00 
        mov     r4,#0x00 
        mov     r5,#0x00 
;     genCmpEq 
;       Peephole 132    changed ljmp to sjmp 
;       Peephole 194    optimized misc jump sequence 
        cjne    r2,#0x02,00103$ 
        cjne    r3,#0x00,00103$ 
        cjne    r4,#0x00,00103$ 
        cjne    r5,#0x00,00103$ 
	... 
 
foo2 - OK (1-byte compare).
