Improvements to clang-tidy
--------------------------

- The 'misc-incorrect-roundings' check was renamed to `bugprone-incorrect-roundings
  <http://clang.llvm.org/extra/clang-tidy/checks/bugprone-incorrect-roundings.html>`_

- The 'misc-string-compare' check was renamed to `readability-string-compare
  <http://clang.llvm.org/extra/clang-tidy/checks/readability-string-compare.html>`_

- New `cppcoreguidelines-avoid-goto
  <http://clang.llvm.org/extra/clang-tidy/checks/cppcoreguidelines-avoid-goto.html>`_ check

  The usage of ``goto`` for control flow is error prone and should be replaced
  with looping constructs. Every backward jump is rejected. Forward jumps are
  only allowed in nested loops.

- New `fuchsia-multiple-inheritance
  <http://clang.llvm.org/extra/clang-tidy/checks/fuchsia-multiple-inheritance.html>`_ check

  Warns if a class inherits from multiple classes that are not pure virtual.

- New `fuchsia-statically-constructed-objects
  <http://clang.llvm.org/extra/clang-tidy/checks/fuchsia-statically-constructed-objects.html>`_ check

  Warns if global, non-trivial objects with static storage are constructed, unless the 
  object is statically initialized with a ``constexpr`` constructor or has no 
  explicit constructor.
  
- New `fuchsia-trailing-return
  <http://clang.llvm.org/extra/clang-tidy/checks/fuchsia-trailing-return.html>`_ check

  Functions that have trailing returns are disallowed, except for those 
  using decltype specifiers and lambda with otherwise unutterable 
  return types.

- New `readability-simd-intrinsics
  <http://clang.llvm.org/extra/clang-tidy/checks/readability-simd-intrinsics.html>`_ check

  Warns if SIMD intrinsics are used which can be replaced by
  ``std::experimental::simd`` operations.
    
- New alias `hicpp-avoid-goto
  <http://clang.llvm.org/extra/clang-tidy/checks/hicpp-avoid-goto.html>`_ to 
  `cppcoreguidelines-avoid-goto <http://clang.llvm.org/extra/clang-tidy/checks/cppcoreguidelines-avoid-goto.html>`_
  added.

- New `bugprone-throw-keyword-missing
  <http://clang.llvm.org/extra/clang-tidy/checks/bugprone-throw-keyword-missing.html>`_ check

  Diagnoses when a temporary object that appears to be an exception is constructed but not thrown.

- New `modernize-use-uncaught-exceptions
  <http://clang.llvm.org/extra/clang-tidy/checks/modernize-use-uncaught-exceptions.html>`_ check

  Finds and replaces deprecated uses of std::uncaught_exception to std::uncaught_exceptions()
