Subject: [Cocoa-sharp] Cocoasharp on Intel
Message-ID: <e8d516190708251119r490c801fnaaaf571790b542a1@mail.gmail.com>

Hi,

I've compiled the latest source and came across a problem with
Event.locationInWindow (I'm trying to read mouse coordinates inside a
View subclass mousedown event).

The Cocoa.Point coordinates return junk on Intel but work fine on PPC.
I checked out the Mac OSX ABI function call reference and looks like
4-8 byte structures are returned in EAX/EDX registers on Intel instead
of memory.

So when i call locationInWindow , it uses objc_sendmsg_stret and fails.

The only fix i could think of was changing ObjCMessaging to check for
IA-32 when return type is valuetype and size of struct is <=8 bytes
and call objc_sendmsg instead.

Has anyone else come across this problem ?
