[avr-gcc-list] Can this be optimised?

[Royce & Sharal Pereira]

Hi, all,

Can this be optimised somehow?
The following code:-
//------------------------------
unsigned int tmp;
//......etc
 tmp= ADCL |(ADCH<<8);
//------------------------------
gets compiled(correctly) as:
 
 1376 04d0 84B1        in r24,36-0x20
 1377 04d2 282F        mov r18,r24
 1378 04d4 3327        clr r19
 1379 04d6 85B1        in r24,37-0x20
 1380 04d8 9927        clr r25
 1381 04da 982F        mov r25,r24
 1382 04dc 8827        clr r24
 1383 04de 282B        or r18,r24
 1384 04e0 392B        or r19,r25
 1385 04e2 3093 0000   sts (tmp)+1,r19
 1386 04e6 2093 0000   sts tmp,r18

Is there a way (without using assembly) to shorten this to:

              in     rxx,     36-0x20
              sts   tmp,    rxx
              in     ryy,     37-0x20
              sts   tmp+1, ryy

Or is in-line assembly the best way? 

Thanks,
