It's about ease of use, not efficiency. The C ABI is indeed "disastrously complex". Just look at the code here: http://www.dsource.org/projects/druntime/browser/trunk/src/core/stdc/stdarg.d The user has to duplicate that code, if he wants to use TypeInfos to unpack the arguments, instead of using compile time types (that va_start) would require. Now think how that would look like on 64 bits. If you're going to use the 64 C ABI for D variadics, you may as well completely remove them from D1 and D2. I don't understand what's so hard about just creating a void*[] on the stack, whose items points to local variables containing the actual argument data. I've done something similar before, when I changed the associative array ABI for by precise GC scanning patch. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
