Still, it sounds like it's a lot over 50. as per past discussions re the architecture "red book" (i.e. cms script file where command line option would print the full machine architecture or just the POO subset, full machine architecture was distributed in red 3ring binders) and compare&swap instruction http://www.garlic.com/~lynn/subtopic.html#smp getting an instruction added could require a lot of justification. so one way of parsing of the reference to 50+ added instructions to improve compiled code efficiency ... could be referring to over 50 of the added instructions were justified for improving compiled code efficiency (w/o saying anything at all about the total number of added instructions and/or what was the justification for any of the other added instructions). ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
