--- Comment #2 from [email protected] 2010-06-28 09:52:04 PDT --- I have not found the thread where this was announced, you can ask to other people about this. I remember a "recent" change in the D GC to ensure the 16 byte alignment of the dynamic arrays and structs. The 16 bytes alignment was introduced because instructions like the SSE2 movapd need 16 byte alignment: http://en.wikipedia.org/wiki/MOVAPD I have recently used it here: http://www.digitalmars.com/webnews/newsgroups.php?art_group=digitalmars.D&article_id=112670 And some other SSE* instructions work with 8 byte alignment too, but they are slower (future CPUs can remove such alignment requirements, some of it has being removed already, so in that future the GC can go back giving 8 bytes aligned memory). -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
