http://d.puremagic.com/issues/show_bug.cgi?id=9691 Summary: Static void arrays are not documented Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: normal Priority: P2 Component: websites AssignedTo: nobody puremagic.com ReportedBy: andrej.mitrovich gmail.com 12:08:29 PDT --- There is no documentation stating how static void arrays are implemented. In particular, what is their actual element size? It seems they're byte-sized: void main() { byte[2] x; int[2] y; void[2] a = x; // ok void[2] b = y; // runtime error: 8 bytes does not fit into 2 bytes } But this needs to be documented. The last statement should probably also be a compile-time error. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=9691 hsteoh quickfur.ath.cx changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hsteoh quickfur.ath.cx I don't like the concept of void[]. It makes me think the element size is 0, and therefore the array is always 0-sized. But it seems the element size of void[] is 1. So then why not ubyte[]? That's basically what it is: you're treating the data as an array of bytes instead of an array of whatever other type it may have been. (Yes an unsafe cast is needed but you're already doing that implicitly by passing T[] to void[] in the first place.) -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=9691 12:59:25 PDT ---I don't like the concept of void[].Well the theory is the GC would avoid scanning ubyte[] for pointers unlike void[]. I don't know if that's true or not, it's been mentioned in the newsgroups a few times. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
