- * Originally the middle line started with l=(((l&0xFF00FF00)>>8)|...
- * It's rewritten as above for two reasons:
- * - RISCs aren't good at long constants and have to explicitely
- * compose 'em with several (well, usually 2) instructions in a
- * register before performing the actual operation and (as you
- * already realized:-) having same constant should inspire the
- * compiler to permanently allocate the only register for it;
- * - most modern CPUs have two ALUs, but usually only one has
- * circuitry for shifts:-( this minor tweak inspires compiler
- * to schedule shift instructions in a better way...
