See 
https://dlang.org/spec/abi.html#function_calling_conventions. 
It defines the D calling convention for Win32 (int return value 
in EAX) and states that it matches the C calling convention on 
all other platforms [but note that the args are actually 
reversed].



Is the inline asm portable between compilers?


LDC supports the DMD-style inline asm too, GDC doesn't.


Thanks!
