Subject: Optimizing C code for speed

Author: Lieven Clarisse

I was wondering if there is a good book about how to write efficient C code. I
am not talking about algorithms, but the way *how* to write things, eg

which is faster :
do {}  while()    or     while () {}

-------
I know for instance that:

ptr=&R[i];
if((*ptr==3)||(*ptr==7)) {;}

is faster then:

if((R[i]==3)||(R[i]==7)) {;}

Is there a good book that reviews all those kinds of tricks?

regards,

Lieven
