-// The following macros are useful for writing death tests.
-
-// Here's what happens when an ASSERT_DEATH* or EXPECT_DEATH* is
-// executed:
-//
-//   1. It generates a warning if there is more than one active
-//   thread.  This is because it's safe to fork() or clone() only
-//   when there is a single thread.
-//
-//   2. The parent process clone()s a sub-process and runs the death
-//   test in it; the sub-process exits with code 0 at the end of the
-//   death test, if it hasn't exited already.
-//
-//   3. The parent process waits for the sub-process to terminate.
-//
-//   4. The parent process checks the exit code and error message of
-//   the sub-process.
-//
-// Examples:
-//
-//   ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");
-//   for (int i = 0; i < 5; i++) {
-//     EXPECT_DEATH(server.ProcessRequest(i),
-//                  "Invalid request .* in ProcessRequest()")
-//                  << "Failed to die on request " << i;
-//   }
-//
-//   ASSERT_EXIT(server.ExitNow(), ::testing::ExitedWithCode(0), "Exiting");
-//
-//   bool KilledBySIGHUP(int exit_code) {
-//     return WIFSIGNALED(exit_code) && WTERMSIG(exit_code) == SIGHUP;
-//   }
-//
-//   ASSERT_EXIT(client.HangUpServer(), KilledBySIGHUP, "Hanging up!");
-//
-// On the regular expressions used in death tests:
-//
-//   GOOGLETEST_CM0005 DO NOT DELETE
-//   On POSIX-compliant systems (*nix), we use the <regex.h> library,
-//   which uses the POSIX extended regex syntax.
-//
-//   On other platforms (e.g. Windows or Mac), we only support a simple regex
-//   syntax implemented as part of Google Test.  This limited
-//   implementation should be enough most of the time when writing
-//   death tests; though it lacks many features you can find in PCRE
-//   or POSIX extended regex syntax.  For example, we don't support
-//   union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and
-//   repetition count ("x{5,7}"), among others.
-//
-//   Below is the syntax that we do support.  We chose it to be a
-//   subset of both PCRE and POSIX extended regex, so it's easy to
-//   learn wherever you come from.  In the following: 'A' denotes a
-//   literal character, period (.), or a single \\ escape sequence;
-//   'x' and 'y' denote regular expressions; 'm' and 'n' are for
-//   natural numbers.
-//
-//     c     matches any literal character c
-//     \\d   matches any decimal digit
-//     \\D   matches any character that's not a decimal digit
-//     \\f   matches \f
-//     \\n   matches \n
-//     \\r   matches \r
-//     \\s   matches any ASCII whitespace, including \n
-//     \\S   matches any character that's not a whitespace
-//     \\t   matches \t
-//     \\v   matches \v
-//     \\w   matches any letter, _, or decimal digit
-//     \\W   matches any character that \\w doesn't match
-//     \\c   matches any literal character c, which must be a punctuation
-//     .     matches any single character except \n
-//     A?    matches 0 or 1 occurrences of A
-//     A*    matches 0 or many occurrences of A
-//     A+    matches 1 or many occurrences of A
-//     ^     matches the beginning of a string (not that of each line)
-//     $     matches the end of a string (not that of each line)
-//     xy    matches x followed by y
-//
-//   If you accidentally use PCRE or POSIX extended regex features
-//   not implemented by us, you will get a run-time failure.  In that
-//   case, please try to rewrite your regular expression within the
-//   above syntax.
-//
-//   This implementation is *not* meant to be as highly tuned or robust
-//   as a compiled regex library, but should perform well enough for a
-//   death test, which already incurs significant overhead by launching
-//   a child process.
-//
-// Known caveats:
-//
-//   A "threadsafe" style death test obtains the path to the test
-//   program from argv[0] and re-executes it in the sub-process.  For
-//   simplicity, the current implementation doesn't search the PATH
-//   when launching the sub-process.  This means that the user must
-//   invoke the test program via a path that contains at least one
-//   path separator (e.g. path/to/foo_test and
-//   /absolute/path/to/bar_test are fine, but foo_test is not).  This
-//   is rarely a problem as people usually don't put the test binary
-//   directory in PATH.

-// #else
-//   // dbg-mode no visible sideeffect.

-// #endif
-// }
-//
-// This will assert that DieInDebugReturn12InOpt() crashes in debug
-// mode, usually due to a DCHECK or LOG(DFATAL), but returns the
-// appropriate fallback value (12 in this case) in opt mode. If you
-// need to test that a function has appropriate side-effects in opt
-// mode, include assertions against the side-effects.  A general

-//
-// EXPECT_DEBUG_DEATH({
-//   // Side-effects here will have an effect after this statement in

-// that have death-tests with stricter requirements than GTEST_HAS_DEATH_TEST
-// can write their own equivalent of EXPECT_DEATH_IF_SUPPORTED and
-// ASSERT_DEATH_IF_SUPPORTED.
-//
-// Parameters:
-//   statement -  A statement that a macro such as EXPECT_DEATH would test
-//                for program termination. This macro has to make sure this
-//                statement is compiled but not executed, to ensure that
-//                EXPECT_DEATH_IF_SUPPORTED compiles with a certain
-//                parameter if and only if EXPECT_DEATH compiles with it.
-//   regex     -  A regex that a macro such as EXPECT_DEATH would use to test
-//                the output of statement.  This parameter has to be
-//                compiled but not evaluated by this macro, to ensure that
-//                this macro only accepts expressions that a macro such as
-//                EXPECT_DEATH would accept.
-//   terminator - Must be an empty statement for EXPECT_DEATH_IF_SUPPORTED
-//                and a return statement for ASSERT_DEATH_IF_SUPPORTED.
-//                This ensures that ASSERT_DEATH_IF_SUPPORTED will not
-//                compile inside functions where ASSERT_DEATH doesn't
-//                compile.
-//
-//  The branch that has an always false condition is used to ensure that
-//  statement and regex are compiled (and thus syntactically correct) but
-//  never executed. The unreachable code macro protects the terminator
-//  statement from generating an 'unreachable code' warning in case
-//  statement unconditionally returns or throws. The Message constructor at
-//  the end allows the syntax of streaming additional messages into the

-// Typical usage:
-//
-//   1. You stream a bunch of values to a Message object.
-//      It will remember the text in a stringstream.
-//   2. Then you stream the Message object to an ostream.
-//      This causes the text in the Message to be streamed
-//      to the ostream.
-//
-// For example;
-//
-//   testing::Message foo;

-//   std::cout << foo;
-//
-// will print "1 != 2".
-//

-//
-// Note that stringstream behaves differently in gcc and in MSVC.  You
-// can stream a NULL char pointer to it in the former, but not in the
-// latter (it causes an access violation if you do).  The Message
-// class hides this difference by treating a NULL char pointer as

-// Value-parameterized tests allow you to test your code with different
-// parameters without writing multiple copies of the same test.
-//
-// Here is how you use value-parameterized tests:
-
-#if 0
-
-// To write value-parameterized tests, first you should define a fixture
-// class. It is usually derived from testing::TestWithParam<T> (see below for
-// another inheritance scheme that's sometimes useful in more complicated
-// class hierarchies), where the type of your parameter values.
-// TestWithParam<T> is itself derived from testing::Test. T can be any
-// copyable type. If it's a raw pointer, you are responsible for managing the
-// lifespan of the pointed values.
-
-class FooTest : public ::testing::TestWithParam<const char*> {
-  // You can implement all the usual class fixture members here.
-};
-
-// Then, use the TEST_P macro to define as many parameterized tests
-// for this fixture as you want. The _P suffix is for "parameterized"
-// or "pattern", whichever you prefer to think. The arguments to the
-// TEST_P macro are the test_suite_name and test_case (both which must be
-// non-empty) that will form the test name.
-
-TEST_P(FooTest, DoesBlah) {
-  // Inside a test, access the test parameter with the GetParam() method
-  // of the TestWithParam<T> class:
-  EXPECT_TRUE(foo.Blah(GetParam()));
-  ...
-}
-
-TEST_P(FooTest, HasBlahBlah) {
-  ...
-}
-
-// Finally, you can use INSTANTIATE_TEST_SUITE_P to instantiate the test
-// case with any set of parameters you want. Google Test defines a number
-// of functions for generating test parameters. They return what we call
-// (surprise!) parameter generators. Here is a summary of them, which
-// are all in the testing namespace:
-//
-//
-//  Range(begin, end [, step]) - Yields values {begin, begin+step,
-//                               begin+step+step, ...}. The values do not
-//                               include end. step defaults to 1.
-//  Values(v1, v2, ..., vN)    - Yields values {v1, v2, ..., vN}.
-//  ValuesIn(container)        - Yields values from a C-style array, an STL
-//  ValuesIn(begin,end)          container, or an iterator range [begin, end).
-//  Bool()                     - Yields sequence {false, true}.
-//  Combine(g1, g2, ..., gN)   - Yields all combinations (the Cartesian product
-//                               for the math savvy) of the values generated
-//                               by the N generators.
-//
-// For more details, see comments at the definitions of these functions below
-// in this file.
-//
-// The following statement will instantiate tests from the FooTest test suite
-// each with parameter values "meeny", "miny", and "moe".
-
-INSTANTIATE_TEST_SUITE_P(InstantiationName,
-                         FooTest,
-                         Values("meeny", "miny", "moe"));
-
-// To distinguish different instances of the pattern, (yes, you
-// can instantiate it more than once) the first argument to the
-// INSTANTIATE_TEST_SUITE_P macro is a prefix (which must be non-empty) that
-// will be added to the actual test suite name. Remember to pick unique prefixes
-// for different instantiations. The tests from the instantiation above will
-// have these names:
-//
-//    * InstantiationName/FooTest.DoesBlah/0 for "meeny"
-//    * InstantiationName/FooTest.DoesBlah/1 for "miny"

-//    * InstantiationName/FooTest.HasBlahBlah/0 for "meeny"
-//    * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
-//    * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
-//
-// You can use these names in --gtest_filter.
-//
-// This statement will instantiate all tests from FooTest again, each
-// with parameter values "cat" and "dog":

-//    * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
-//    * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
-//
-// Please note that INSTANTIATE_TEST_SUITE_P will instantiate all tests
-// in the given test suite, whether their definitions come before or
-// AFTER the INSTANTIATE_TEST_SUITE_P statement.
-//
-// Please also note that generator expressions (including parameters to the
-// generators) are evaluated in InitGoogleTest(), after main() has started.
-// This allows the user on one hand, to adjust generator parameters in order
-// to dynamically determine a set of tests to run and on the other hand,
-// give the user a chance to inspect the generated tests with Google Test
-// reflection API before RUN_ALL_TESTS() is executed.
-//
-// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
-// for more examples.
-//
-// In the future, we plan to publish the API for defining new parameter
-// generators. But for now this interface remains part of the internal
-// implementation and is subject to change.
-//
-//
-// A parameterized test fixture must be derived from testing::Test and from
-// testing::WithParamInterface<T>, where T is the type of the parameter
-// values. Inheriting from TestWithParam<T> satisfies that requirement because
-// TestWithParam<T> inherits from both Test and WithParamInterface. In more
-// complicated hierarchies, however, it is occasionally useful to inherit
-// separately from Test and WithParamInterface. For example:
-
-class BaseTest : public ::testing::Test {
-  // You can inherit all the usual members for a non-parameterized test
-  // fixture here.
-};
-
-class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {

-// This file implements a universal value printer that can print a
-// value of any type T:
-//
-//   void ::testing::internal::UniversalPrinter<T>::Print(value, ostream_ptr);
-//
-// A user can teach this function how to print a class type T by
-// defining either operator<<() or PrintTo() in the namespace that
-// defines T.  More specifically, the FIRST defined function in the
-// following list will be used (assuming T is defined in namespace
-// foo):
-//
-//   1. foo::PrintTo(const T&, ostream*)
-//   2. operator<<(ostream&, const T&) defined in either foo or the
-//      global namespace.
-//
-// However if T is an STL-style container then it is printed element-wise
-// unless foo::PrintTo(const T&, ostream*) is defined. Note that
-// operator<<() is ignored for container types.
-//
-// If none of the above is defined, it will print the debug string of
-// the value if it is a protocol buffer, or print the raw bytes in the
-// value otherwise.
-//
-// To aid debugging: when T is a reference type, the address of the
-// value is also printed; when T is a (const) char pointer, both the
-// pointer value and the NUL-terminated string it points to are
-// printed.
-//
-// We also provide some convenient wrappers:
-//
-//   // Prints a value to a string.  For a (const or not) char
-//   // pointer, the NUL-terminated string (but not the pointer) is
-//   // printed.
-//   std::string ::testing::PrintToString(const T& value);
-//
-//   // Prints a value tersely: for a reference type, the referenced
-//   // value (but not the address) is printed; for a (const or not) char
-//   // pointer, the NUL-terminated string (but not the pointer) is
-//   // printed.
-//   void ::testing::internal::UniversalTersePrint(const T& value, ostream*);
-//
-//   // Prints value using the type inferred by the compiler.  The difference
-//   // from UniversalTersePrint() is that this function prints both the
-//   // pointer and the NUL-terminated string for a (const or not) char pointer.
-//   void ::testing::internal::UniversalPrint(const T& value, ostream*);
-//
-//   // Prints the fields of a tuple tersely to a string vector, one
-//   // element for each field. Tuple support must be enabled in
-//   // gtest-port.h.
-//   std::vector<string> UniversalTersePrintTupleFieldsToStrings(
-//       const Tuple& value);
-//
-// Known limitation:
-//
-// The print primitives print the elements of an STL-style container
-// using the compiler-inferred type of *iter where iter is a
-// const_iterator of the container.  When const_iterator is an input
-// iterator but not a forward iterator, this inferred type may not
-// match value_type, and the print output may be incorrect.  In
-// practice, this is rarely a problem as for most containers
-// const_iterator is a forward iterator.  We'll fix this if there's an
-// actual need for it.  Note that this fix cannot rely on value_type
-// being defined as many user-defined container types don't have
-// value_type.

-// Type-parameterized tests are abstract test patterns parameterized

-// units.
-//
-// If you are designing an interface or concept, you can define a
-// suite of type-parameterized tests to verify properties that any
-// valid implementation of the interface/concept should have.  Then,
-// each implementation can easily instantiate the test suite to verify
-// that it conforms to the requirements, without having to write
-// similar tests repeatedly.  Here's an example:
-
-#if 0

-// First, define a fixture class template.  It should be parameterized
-// by a type.  Remember to derive it from testing::Test.
-template <typename T>

-// prefer):

-// Then, use TYPED_TEST_P() to define as many type-parameterized tests
-// for this type-parameterized test suite as you want.

-  // Inside a test, refer to TypeParam to get the type parameter.
-  TypeParam n = 0;
-  ...
-}
-

-// case.

+//  2023-11-29: Vulkan: Fixed mismatching allocator passed to vkCreateCommandPool() vs vkDestroyCommandPool(). (#7075)
