Dehao Chen 34cfcb29aa Make ICP uses PSI to check for hotness.
Summary: Currently, ICP checks the count against a fixed value to see if it is hot enough to be promoted. This does not work for SamplePGO because sampled count may be much smaller. This patch uses PSI to check if the count is hot enough to be promoted.

Matt Morehouse f051f5d1e6 Integrate Kostya's clang-proto-fuzzer with LLVM.
Summary:
The clang-proto-fuzzer models a subset of C++ as a protobuf and
uses libprotobuf-mutator to generate interesting mutations of C++
programs.  Clang-proto-fuzzer has already found several bugs in
Clang (e.g., https://bugs.llvm.org/show_bug.cgi?id=33747,
https://bugs.llvm.org/show_bug.cgi?id=33749).

As with clang-fuzzer, clang-proto-fuzzer requires the following
cmake flags:
- CMAKE_C_COMPILER=clang
- CMAKE_CXX_COMPILER=clang++
- LLVM_USE_SANITIZE_COVERAGE=YES  // needed for libFuzzer
- LLVM_USE_SANITIZER=Address  // needed for libFuzzer

In addition, clang-proto-fuzzer requires:
- CLANG_ENABLE_PROTO_FUZZER=ON

clang-proto-fuzzer also requires the following dependencies:
- binutils  // needed for libprotobuf-mutator
- liblzma-dev  // needed for libprotobuf-mutator
- libz-dev  // needed for libprotobuf-mutator
- docbook2x  // needed for libprotobuf-mutator
- Recent version of protobuf [3.3.0 is known to work]

A working version of libprotobuf-mutator will automatically be
downloaded and built as an external project.

Implementation of clang-proto-fuzzer provided by Kostya
Serebryany.

Richard Smith f1a425edb7 PR19668, PR23034: Fix handling of move constructors and deleted copy
constructors when deciding whether classes should be passed indirectly.

This fixes ABI differences between Clang and GCC:

 * Previously, Clang ignored the move constructor when making this
   determination. It now takes the move constructor into account, per
   https://github.com/itanium-cxx-abi/cxx-abi/pull/17 (this change may
   seem recent, but the ABI change was agreed on the Itanium C++ ABI
   list a long time ago).

 * Previously, Clang's behavior when the copy constructor was deleted
   was unstable -- depending on whether the lazy declaration of the
   copy constructor had been triggered, you might get different behavior.
   We now eagerly declare the copy constructor whenever its deletedness
   is unclear, and ignore deleted copy/move constructors when looking for
   a trivial such constructor.

This also fixes an ABI difference between Clang and MSVC:

 * If the copy constructor would be implicitly deleted (but has not been
   lazily declared yet), for instance because the class has an rvalue
   reference member, we would pass it directly. We now pass such a class
   indirectly, matching MSVC.

Zachary Turner 59e3ae827d [PDB] Fix linking of function symbols and local variables.
The compiler outputs PROC32_ID symbols into the object files
for functions, and these symbols have an embedded type index
which, when copied to the PDB, refer to the IPI stream.  However,
the symbols themselves are also converted into regular symbols
(e.g. S_GPROC32_ID -> S_GPROC32), and type indices in the regular
symbol records refer to the TPI stream.  So this patch applies
two fixes to function records.
  1. It converts ID symbols to the proper non-ID record type.
  2. After remapping the type index from the object file's index
     space to the PDB file/IPI stream's index space, it then
     remaps that index to the TPI stream's index space by.

Besides functions, during the remapping process we were also
discarding symbol record types which we did not recognize.
In particular, we were discarding S_BPREL32 records, which is
what MSVC uses to describe local variables on the stack.  So
this patch fixes that as well by copying them to the PDB.

Anna Thomas 9b6e12f3dc [LoopVectorize] Fix assertion failure in Fcmp vectorization
Summary:
When vectorizing fcmps we can trip on incorrect cast assertion when setting the
FastMathFlags after generating the vectorized FCmp.
This can happen if the FCmp can be folded to true or false directly. The fix
here is to set the FastMathFlag using the FastMathFlagBuilder *before* creating
the FCmp Instruction. This is what's done by other optimizations such as
InstCombine.
Added a test case which trips on cast assertion without this patch.

Aaron Ballman b6fd726f9c Restore previous structure ABI behavior for bit-fields with the packed attribute for PS4 targets.
An ABI change was introduced in r254596 that modified structure layouts when the 'packed' attribute was used on one-byte bitfields. Since the PS4 target needs to maintain backwards compatibility for all structure layouts, this change reintroduces the old behavior for PS4 targets only. It also introduces PS4 specific cases to the relevant test.

Roman Gareev 1563f039f5 Use SCEV information for the second level aliasing
We introduce another level of alias metadata to distinguish the individual
non-aliasing accesses that have inter iteration alias-free base pointers
marked with "Inter iteration alias-free" mark nodes. To distinguish two
accesses, the comparison of raw pointers representing base pointers is used.

In case of, for example, ublas's prod function that implements GEMM, and
DeLiCM we can get accesses to same location represented by different raw
pointers. Consequently, we create different alias sets that can prevent
accesses from, for example, being sinked or hoisted.

To avoid the issue, we compare the corresponding SCEV information instead
of the corresponding raw pointers.

For example, we got reports from users on Windows that have a tool that scan a
build output dir (but skip .obj files). The tool would keep the "foo.obj-12345"
file open, and then when clang tried to rename the temp file to the final

tools like this could now have a rule to ignore .tmp files.

Summary:
Previously, clang-format would insert whitespace in union types nested in object
and array types, as it wouldn't recognize those as a type operator:

    const x: {foo: number | null};
    const x: [number | null];

While this is correct for actual binary operators, clang-format should not
insert whitespace into union and intersection types to mark those:

    const x: {foo: number|null};
    const x: [number|null];

This change propagates that the context is not an expression by inspecting
the preceding token and marking as non-expression if it was a type colon.
