832be2d52d7695cf72fd70248909791fb8ad1003 by Gennadiy Rozental <rogeeff@google.com>:
Migrate some FlagImpl fields to bit fields.
To save padding space we are migrating some fields representing bool and enums into bit fields. Eventually we'll use remaining padding space for call_once control flag.
No other semantic changes made in this CL.

Introduce struct to represent storage for flag value and normalize naming of internal structs in Flag implementation.
There is no semantic changes in this CL. All the internal structs are now named as Flag... We also stop using flags_internal:: qualifications for most of them since the names are unique enough by themselves.

Improve ABSL_ATTRIBUTE_PACKED documentation
Recommend to apply ABSL_ATTRIBUTE_PACKED to structure members instead of to an entire structure because applying this attribute to an entire structure may cause the compiler to generate suboptimal code. It reduces the alignment of the data structure from a value larger than one to one. When applied to a structure, ABSL_ATTRIBUTE_PACKED reduces the alignment of a structure (alignof()) to 1. As a result, the compiler can no longer assume that e.g. uint32 members are aligned on a four byte boundary and hence is forced to use single-byte load and store instructions on CPU architectures that do not support non-aligned loads or stores.

Separate the initialization of NumCPUs() and NominalCPUFrequency()
The OSS version of Abseil never needs to call NominalCPUFrequency().
In some configurations, initializing NominalCPUFrequency() requires
spending at least 3ms measuring the CPU frequency. By separating the
initialization from NumCPUs(), which is called in most configurations,
we can save at least 3ms of program startup time.

Enable building Abseil as a DLL.
This is currently experimental and unsupported.
This CL does a few things:
1. Adds the ABSL_DLL macro to any class holding a static data member, or to global constants in headers.
2. Adds a whitelist of all files in the DLL and all the build targets that are conglomerated into the DLL.
3. When BUILD_SHARED_LIBS is specified, any build target that would be in the DLL still exists, but we swap out all of it's dependencies so it just depends on abseil_dll

Removes the static initializer for LookupTables<absl::uint128>::kVmaxOverBase
Uses template specialization to hard code the resulting array.
Static initializers are problematic for a number of reasons. Not only
are they responsible for the static initialization order fiasco, but
they are in the critical path during program startup. For these
reasons, the Google C++ style guide strongly discourages them (and
forbids them when they are not trivially destructible), and Chromium
even has a test forbidding them.

fdb3474d76c2ee0371ccdf7593a78137c03a3f58 by Greg Falcon <gfalcon@google.com>:
Step 1 of 2 to fix our CCTZ fork to respect inline namespaces.
CCTZ uses a linker flag to simulate weak symbol support in MSVC. This takes the form of a #pragma that includes the mangled names of two types: the symbol to treat as weak, and the symbol to use as its default value if no override is provided.
When Abseil is configured to use inline namespaces, the mangled names of these symbols change, and the pragma should change to reflect that. Fortunately for us, MSVC name mangling is simple enough that we can generate the needed string literals in the preprocessor.
This CL introduces the new macros; the uses will be introduced in a follow-up CL.

Deflaking MockingBitGen test. Because MockingBitGen can return random values,
it is inherently flaky. For log-unifrom, 2040 is a common enough value that
tests failed unreasonably frequently. Replacing it with a significantly larger
value so as to be much less common. 50000 is a good choice because it is (tied for) the least likely to occur randomly from this distribution, but is still in the distribution.

Remove construction tests for the internal `CompressedTuple<std::any>` instantiation. This was not guaranteed to work for the reasons that `std::tuple<std::any>` copy construction does not actually work by standard specification (some implementations introduce workarounds for this). In GCC9, `CompressedTuple<std::any>` and `std::tuple<std::any>` both fail for the same reasons, and a proper "fix" requires updating `std::any`, which is out of our control.

Enable compile-time enforcement that absl::Substitute patterns to not contain unescaped $ symbols.
absl::Substitute already considers unescaped $ symbols undefined behavior and crashes when it's passed them in debug builds. Some code isn't ever built in debug mode, though, and inadvertently used some unescaped $ symbols, which led to surprising results. This change will prevent that problem from happening in the future.

This CL introduces following changes to the class FlagImpl:
* We eliminate the CommandLineFlagLocks struct. Instead callback guard and callback function are combined into a single CallbackData struct, while primary data lock is stored separately.
* CallbackData member of class FlagImpl is initially set to be nullptr and is only allocated and initialized when a flag's callback is being set. For most flags we do not pay for the extra space and extra absl::Mutex now.
* Primary data guard is stored in data_guard_ data member. This is a properly aligned character buffer of necessary size. During initialization of the flag we construct absl::Mutex in this space using placement new call.
* We now avoid extra value copy after successful attempt to parse value out of string. Instead we swap flag's current value with tentative value we just produced.

28e76c08ea7185a7ff9f4e0e02ae565fbbf7980f by Greg Falcon <gfalcon@google.com>:
Implementation detail change.
Introduce ABSL_NAMESPACE_BEGIN and _END annotation macros which indicate the beginning and end of a `namespace absl` scope. Currently these do nothing, but they will be used to inject an inline namespace for LTS builds (to avoid symbol collisions against other Abseil versions).
These macros should not be used by end users, because end users should never write `namespace absl {` in their own code.
This CL applies these annotations to all code under //absl/base/. The rest of Abseil will be annotated in this way in follow-up CLs.

Add comments and relax memory orders in base_internal::CallOnceImpl.
Add a comment to document the memory order guarantee if
base_internal::SpinLockWait() is called and returns kOnceDone.
Add a comment for the load/store sequence in base_internal::CallOnceImpl
based on Mike Burrows' explanation.
The atomic load of 'control' in the #ifndef NDEBUG block does not need
std::memory_order_acquire. It can use std::memory_order_relaxed.
The atomic compare_exchange_strong of 'control' does not need
std::memory_order_acquire in the success case. It can use
std::memory_order_relaxed.

Removing a bunch of __restricts that amount to no performance differences. One
of these is the cause of https://github.com/abseil/abseil-cpp/issues/396. In
particular, in one of the Vector128Store functions, restricts on two pointers
that were indeed aliased seems to be the root cause of the issues.

ResetThreadIdentity does not need to clear identity->waiter_state.
ResetThreadIdentity is only called by NewThreadIdentity. NewThreadIdentity is

PerThreadSem::Init, which initializes identity->waiter_state, immediately after
calling NewThreadIdentity. Therefore ResetThreadIdentity does not need to clear
identity->waiter_state.

Delete the f->header.magic check in LowLevelAlloc::Free().
The f->header.magic check in LowLevelAlloc::Free() is redundant, because
AddToFreeList() will immediately perform the same check.
Also fix a typo in the comment that documents the lock requirements for
Next(). The comment should say "L >= arena->mu", which is equivalent to
EXCLUSIVE_LOCKS_REQUIRED(arena->mu).
NOTE: LowLevelAlloc::Free() performs the f->header.magic check without
holding the arena lock. This may have caused the TSAN data race warning
reported in bug 143697235.

ce8c9a63109214519b5a7eaecef2c663c4d566df by Greg Falcon <gfalcon@google.com>:
Implement the config options for our four main C++ forward compatibility types.
These options control whether the names `any`, `optional`, `string_view`, and `variant` in namespace `absl` are aliases to the corresponding C++17 types in namespace `std`. By default, we continue to auto-detect the configuration of the compiler being run.
These options are not intended to be modified on the command line (as -D flags, say). Instead, the options.h file can be modified by distributors of Abseil (e.g., binary packagers, maintainers of local copies of Abseil, etc.)
Changing options will change Abseil in an ODR sense. Any program must only link in a single version of Abseil. Linking libraries that use Abseil configured with different options is an error: there is no ABI compatibility guarantee when linking different configurations, even if the Abseil versions used are otherwise exactly identical.

Use explicit static_cast<double> for int64_t to double conversion
This uses an explicit static_cast<double>() in the int64_t to double comparisons in duration.cc's SafeAddRepHi. This satisfies clang's -Wimplicit-int-to-float-conversion warning (with https://reviews.llvm.org/D64666).

a9ac6567c0933d786d68c10011e3f3ff9deedf89 by Greg Falcon <gfalcon@google.com>:
Add absl::FunctionRef, a type analogous to the proposed C++23 std::function_ref.
Like std::function, FunctionRef can be used to type-erase any callable (invokable) object. However, FunctionRef works by reference: it does not store a copy of the type-erased object. If the wrapped object is destroyed before the FunctionRef, the reference becomes dangling.
FunctionRef relates to std::function in much the same way that string_view relates to std::string.
Because of these limitations, FunctionRef is best used only as a function argument type, and only where the function will be invoked immediately (rather than saved for later use). When `const std::function<...>&` is used in this way, `absl::FunctionRef<...>` is a better-performing replacement.

Try to become idle only when there is no wakeup.
Immediately after waking up (when futex wait returns), the current thread tries
to become idle doing bunch of memory loads and a branch. Problem is that there
is a good chance that we woke up due to a wakeup, especially for actively used
threads. For such wakeups, calling MaybeBecomeIdle() would be a waste of
cycles.
Instead, call MaybeBecomeIdle() only when we are sure there is no wakeup. For
idle threads the net effect should be the same. For active, threads this will
be more efficient.
Moreover, since MaybeBecomeIdle() is called before waiting on the futex, the
current thread will try to become idle before sleeping. This should result
in more accurate idleness and more efficient release of thread resources.

Fix AtomicHook init-order fiasco under MSVC 2019.
On this platform, constexpr static init sometimes happens after dynamic init =/. When it does, we should not zero hook_ (overwriting the value written there by dynamic init); instead we should leave it alone. This works even when constexpr static init goes first since all uses of AtomicHook should have static storage duration and be zero-initialized.

Avoid the compiler reloading __is_long() on string_view(const string&)
The underlying cause is that the compiler assume a scenario where string_view is created with placement new into memory occupied by the input, so the store to 'ptr' can affect the value / result of size(); i.e., __is_long() reloads the __size value).
Example code: string_view1 demonstrates the problem, string_view2 DTRT.

struct string_view1 {
string_view1(const char* ptr, size_t n) : ptr(ptr), n(n) {}

const char* ptr;
size_t n;
