The platform run on isn't what's relevant, it's if the app is a 32 or 64 bit app. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

For in-depth analysis, this feature is nowhere near as comprehensive as the hardware performance counters which have existed since the Pentium MMX days (and which seem very under-utilized -- they are really fantastic). I think AMD is being deliberately misleading. I take offence to this section: These counters are used by the AMD CodeAnalyst Performance Analyzer and provide deep insight into application and system performance. However, each time a data sample is gathered, the processor must take an interrupt to a kernel-mode driver, and that takes hundreds or thousands of cycles. It *sounds* as though this is talking about the hardware performance counters. But it ISNT!! It's talking about their performance analyzer. It is possible to get the same data they're talking about, without calling into kernel mode all the time. You do NOT need to use their driver. So, it's maybe a 5-10% improvement over what already exists. May be useful for JIT compilers, but it isn't really anything to get terribly excited about. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

Chances are high it's not a compiler change but rather some library changes in either the core runtime or in phobos. However, whatever it is, it'd need to be done in a cpu agnostic manner with the potential to be optimized for AMD. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
