Re: On KEILs Dhrystone benchmarks --again

I have tried to choose my words carfully, to avoid accusing KEIL of
anything. (Except that I do feel that KEIL should have provided an
analysis.)

I think you were referring to the remark that Dhrystone may be
inappropriate for embedded systems software. For that remark, I cited
Richard York, and a link to his paper is near the bottom of my
article.

This is a good point. I will take this into account when I update my
article on the Dhrystone benchmark.

Thanks for posting, anf kind regards,
