Hi,
template<typename T>struct A
{
int foo;
struct B : A { using A::foo; }; // (1)
struct C : A<T> { using A::foo; }; // (2)
};
There are two problems in this PR. Firstly, for (1) it seems to work,
but in reality the lookup for foo is not performed. Hence, I have
modified dfs_lookup_base so that (1) and (2) be treated equivalently.
For (2), the lookup was failing because the flag
BINFO_DEPENDENT_BASE_P was set. It think it should not be set for this
special case, however, I'm not sure I have unset it at the right
place. A slight tweak was also needed in lookup_field_r so that (1)
work correctly.
Tested x86_64-unknown-linux-gnu without regressions.
