GoingNative 7: VC11 Auto-Vectorizer, C++ NOW, Lang.NEXT
Mar 31, 2012 at 10:52 PMJim, Jim and Charles - thanks for a great talk! I'd love to hear more from the compiler makers.
Can argument decoration aid the vectorizer?
Maybe decorating an argument as __declspec(align(16)) can make the vectorizer load registers with aligned instructions?
Does decorating arguments with __restrict have *any* impact currently? Can you give an example of the effect it has?
STL Iterator Debugging and Secure SCL
Oct 23, 2010 at 1:16 AMBoth Charles & STL - thanks for a great interview!
If I understood correctly, a major factor that makes HAS_ITERATOR_DEBUGGING sos slow is the need to traverse the entire iterator linked list to remove a single iteratr when it is destroyed. Maybe making the list doubly-linked can accelerate that? (the added space cost seems well worth it)
