<pre>__uuidof mangling is quite special, consider the following:
typedef struct _GUID
{
unsigned long Data1;
unsigned short Data2;
unsigned short Data3;
unsigned char Data4[8];
} GUID;
struct __declspec(uuid("12345678-1234-1234-1234-123456789abC")) uuid;
template <const _GUID&>
struct bar {
};
bar<__uuidof(uuid)> x;
this should be mangled like such:
?x@@3U?$bar@$E?_GUID_12345678_1234_1234_1234_123456789abc@@3U__s_GUID@@B@@A
Essentially, this has to be handled as-if we had:
struct __s_GUID _GUID_12345678_1234_1234_1234_123456789abc;
There is a pretty obvious problem, what is __s_GUID? It doesn't exist in any
AST. Heck, it's technically the flat-out wrong type, we should be looking at a
_GUID.</pre>
