<pre>Is it possible to officially add the Watcom calling convention to LLVM and
Clang in order to support calling code from legacy libraries and DLLs without
any inline assembly hacks to pass parameters correctly?
Basically the issue is that parameters are passed left-to-right into EAX, ECX,
EDX, and EBX, then everything else right-to-left onto the stack. Using
__fastcall or __stdcall doesn't help either, even though the conventions behave
pretty much like Watcom's.</pre>
