Bug ID: 20661
Summary: Top half of __m256i is not filled when returned from a
function
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++

Test case
When returning an std::array (or boost::array) of __m256i, the top half of the
vector is not filled. In the attached test case, assigning t to a works as
expected but when t is assigned to c via the eval function, the top half of the
vector is lost.
This also works with g++.
