They have an urgent need for a C compiler which uses all of the speed features of the '486 chip for a vision processing application. Do you know of any? Are any at the beta test stage? Where can they be accessed? If this is not interesting to the net, please reply directly. Thanks Mick Carrick Department of Animal Science UNE, Armidale, NSW, 2351 Australia mcarrick@gara.une.oz.au [It is my impression that optimizations for the 486 are in most cases the same ones that you'd do for the 386. There are a few places on the 486 where you can avoid pipeline stalls by reordering instructions, and a few instructions that are relatively faster or slower, other than that anything you'd do for a 386 applies equally. -John] -- Send compilers articles to compilers@iecc.cambridge.ma.us or {ima | spdcc | world}!iecc!compilers.
