A few tests are examining code locations and looking af the resulting line
numbers to verify that GoogleTest shows those to users correctly. Some of those
locations change when clang-format is run. For those locations, I've wrapped
portions in:
// clang-format off
...
// clang-format on

There may be other locations that are currently not tickled by running
clang-format.

cleanup: fix spurious MSAN warnings with Clang 12
PiperOrigin-RevId: 378430614

Add support to run gtest on Xtensa platform.

This add support to run GTest base test suits on Xtensa
(https://ip.cadence.com/ipportfolio/tensilica-ip) base simulator.
Xtensa only provides libc and some basic operations and does not run an
operating system by default.

An always false condition was remove from Normalize member function of
FilePath and the body of the function which was poorly writen is
improved.

Added various conditional compliations for ESP8266 to stub out
missing functionality.

Added support for ESP8266 Arduino platform.

Refactored Arduino defines to use the GTEST_OS_* model.

Extend gtest-port and stubs for ESP_PLATFORM

ESP_PLATFORM is the macro used to indicate compilation for the ESP32
using the esp-idf. This isn't a fully posix compatible system so
various features of google test need to be stubbed out in order for
it to work. It's oddly similar to the GTEST_OS_WINDOWS_PHONE setup.

Cast some values as their unsigned equivalents or `size_t` to match the
parameter type used for the template object under test. Also, provide
UInt32 equivalent delegate methods for some callers (with
int-equivalents for backwards compatibility).

This closes #2146.
Signed-off-by: Enji Cooper <yaneurabeya@gmail.com>

Added Arduino to the embedded platform list to allow for a stubbed out version
of GetCurrentDir.

Internal Change

PiperOrigin-RevId: 227575279

Remove the #ifs for old, unsupported and buggy compilers:
* old versions of GCC & MSVC
* Symbian

Now that googletest has moved to C++11, it should no longer
use NULL or 0 for the null pointer. This patch converts all
such usages to nullptr using clang-tidy.

This prevents LLVM from issuing -Wzero-as-null-pointer-constant
warnings.

Comments changes, no functionality changes. 

Add MemorySanitizer annotations in gtest printers. Also remove unused variable kPathSeparatorString.

Removes testing::internal::String::Format(), which causes problems as it truncates the result at 4096 chars. Also update an obsolete link in comment.

changes that haven't made it to svn. The descriptions of each change are listed
below.

- Fixes some python shebang lines.

- Add ElementsAreArray overloads to gmock. ElementsAreArray now makes a copy of
  its input elements before the conversion to a Matcher. ElementsAreArray can
  now take a vector as input. ElementsAreArray can now take an iterator pair as
  input.

- Templatize MatchAndExplain to allow independent string types for the matcher
  and matchee. I also templatized the ConstCharPointer version of
  MatchAndExplain to avoid calls with "char*" from using the new templated
  MatchAndExplain.

- Fixes the bug where the constructor of the return type of ElementsAre() saves
  a reference instead of a copy of the arguments.

- Extends ElementsAre() to accept arrays whose sizes aren't known.

- Switches gTest's internal FilePath class from testing::internal::String to
  std::string. testing::internal::String was introduced when gTest couldn't
  depend on std::string.  It's now deprecated.

- Switches gTest & gMock from using testing::internal::String objects to
  std::string. Some static methods of String are still in use.  We may be able
  to remove some but not all of them.  In particular, String::Format() should
  eventually be removed as it truncates the result at 4096 characters, often
  causing problems.

Adds support for alternate path separator on Windows, and make all tests pass with CMake and VC++ 9 (by Manuel Klimek).

Publishes the even listener API (by Vlad Losev); adds OS-indicating macros to simplify gtest code (by Zhanyong Wan).

Simplifies implementation by defining a POSIX portability layer; adds the death test style flag to --help.

Implements death tests on Windows (by Vlad Losev); enables POSIX regex on Mac and Cygwin; fixes build issue on some Linux versions due to PATH_MAX.

Fixes the bug where the XML output path is affected by test changing the current directory.  By Stefan Weigand.
