Remove an old workaround that was kept around for ABI-compatibility on x86-64 between different LLVM versions. This means LLVM r67588 is required if you want to compile for x86-64, otherwise the backend will assert when you try to return e.g. struct { int i; char c; } from a function. (In particular, this is no longer compatible with LLVM 2.5) It also means that any code returning small structs on x86-64 will probably need to be recompiled in order to be linkable to code compiled with this change.

module typeinfo3;

typedef int int_t;

void main()
{
    /*int_t i;
    auto ti = typeid(typeof(i));
    printf("%s\n",ti.toString.ptr);
    assert(ti.toString() == "typeinfo3.int_t");
    assert(ti.next !is null);
    assert(ti.next.toString() == "int");
    assert(ti.init is null);*/
}
