The z/Linux C compiler uses them. I was debugging a problem and was surprised to see the vector instructions used. In that case, it wasn't really needed as it was dealing with a single element, but perhaps the compiler generated the code to use the vector register rather than saving/ reloading a general register. I can't recall if I've seen them used with the z/OS C compiler, but it wouldn't surprise me. -- Don Poitras - SAS Development - SAS Institute Inc. - SAS Campus Drive [email protected] (919) 531-5637 Cary, NC 27513 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
