I don't think static analysis is appropriate here. An optimized rasterop/bitblt routine can make good use of 20-30 registers. On a typical workstation, those registers would be worthwhile even if no other code used them. (Those with bitblt hardware could try optimizing namei().) -- David DiGiacomo {decvax, dual, ihnp4, ucbvax}!sun!david Sun Microsystems, Mt. View, CA (415) 960-7495
