Extended Description

On the demo cgi:

http://www.llvm.org/demo/index.cgi

enter this code:

struct S {
double d;
};

S foo(S);

double bar() {
S s;
s = foo(s);
return s.d;
}

Check C++ as source language and check "Show LLVM C++ API code".

The C++ API code shown does not show any use of ParamAttr::ByVal, despite `foo' being declared as

declare void @​_Z3foo1S(%struct.S* sret , %struct.S* byval)

This was fixed in TOT:

updating llvm-gcc / llvm2cpp on website is another problem

The demo page gets updated with each release. So right now its 2.2 and won't be updated til 2.3 comes out (~May).
