[X86] Implement old kunpck intrinsics using vector ops on vXi1 instead of integer shift/and/or

Summary:
kunpck intrinsics were removed in favor of native IR a few months ago. The implementation lowers them as by operation on the integer types passed to the intrinsic and then just shifting, masking, and oring them together. A special X86 DAG combine was added to recognize this patter and turn it into a concat_vector operation.

I think it makes more sense to keep the IR implementation closer to vector operations on vXi1. Given that we expect these builtins to be used around other builtins that operate on k-registers which we try to represent in IR with vXi1. InstCombine should be able to get rid of the bitcasts between integers and vXi1 leaving only the vector operations.

6 years agoAdd `__reference_binds_to_temporary` trait for checking safe reference initialization.
Eric Fiselier [Fri, 12 Jan 2018 00:09:37 +0000 (00:09 +0000)]
Add `__reference_binds_to_temporary` trait for checking safe reference initialization.

Summary:
The STL types `std::pair` and `std::tuple` can both store reference types. However their constructors cannot adequately check if the initialization of reference types is safe.  For example:

```
std::tuple<std::tuple<int> const&> t = 42;
// The stored reference is already dangling.
```

Libc++ has a best effort attempts in tuple to diagnose this, but they're not able to handle all valid cases (If I'm not mistaken). For example initialization of a reference from the result of a class's conversion operator.  Libc++ would benefit from having a builtin traits which can provide a much better implementation.

This patch introduce the `__reference_binds_to_temporary(T, U)` trait  that determines whether a reference of type `T` bound to an expression of type `U` would bind to a materialized temporary object.

Note that the trait simply returns false if `T` is not a reference type instead of reporting it as an error.

```
static_assert(__is_constructible(int const&, long));
static_assert(__reference_binds_to_temporary(int const&, long));

Make internal/private GVs implicitly dso_local.

While updating clang tests for having clang set dso_local I noticed
that:

- There are *a lot* of tests to update.
- Many of the updates are redundant.

They are redundant because a GV is "obviously dso_local". This patch
starts formalizing that a bit by requiring that internal and private
GVs be dso_local too. Since they all are, we don't have to print
dso_local to the textual representation, making it a bit more compact
and easier to read.
