Please post command line used to compile and assembler produced.
I cannot reproduce this on 4.4 or 4.2.2.
At high optimisation (-Os) it compiles to load PORTC with 3 directly.
(as one would expect):
13 /* prologue: frame size=0 */
14 /* prologue end (size=0) */
15 0000 8FE0 ldi r24,lo8(15)
16 0002 87B9 out 39-0x20,r24
17 0004 83E0 ldi r24,lo8(3)
18 0006 90E0 ldi r25,hi8(3)
19 0008 88B9 out 40-0x20,r24
20 000a 80E0 ldi r24,lo8(0)
21 000c 90E0 ldi r25,hi8(0)
22 /* epilogue: frame size=0 */
23 000e 0895 ret
