Agreed.

--- Comment #14 from Jakub Jelinek ---
For the base class alignment vs. alignment of base class members, I think
testcases could be e.g. like:
struct B { char a __attribute__((aligned (8))); };
struct A : public B {};
A
foo (int x, A y)
{

aarch64_function_arg_alignment
has:
for (tree field = TYPE_FIELDS (type); field; field = DECL_CHAIN (field))
alignment = std::max (alignment, DECL_ALIGN (field));
and thus has similar problem (no

Started with r225465.

I should add that turning on lto works around the issue both in the simple code
attached and for the original issue I was having in julia (i.e. compiling llvm
with LTO makes the issue go away).
