+// SizeClassMap maps allocation sizes into size classes and back.
+// Class 0 always corresponds to size 0.
+// The other sizes are controlled by the template parameters:
+//   kMinSizeLog: defines the class 1    as 2^kMinSizeLog.
+//   kMaxSizeLog: defines the last class as 2^kMaxSizeLog.
+//   kMidSizeLog: the classes starting from 1 increase with step
+//                2^kMinSizeLog until 2^kMidSizeLog.
+//   kNumBits: the number of non-zero bits in sizes after 2^kMidSizeLog.
+//             E.g. with kNumBits==3 all size classes after 2^kMidSizeLog
+//             look like 0b1xx0..0, where x is either 0 or 1.
+//
+// Example: kNumBits=3, kMinSizeLog=4, kMidSizeLog=8, kMaxSizeLog=17:
+//
+// Classes 1 - 16 correspond to sizes 16 to 256 (size = class_id * 16).
+// Next 4 classes: 256 + i * 64  (i = 1 to 4).
+// Next 4 classes: 512 + i * 128 (i = 1 to 4).
+// ...
+// Next 4 classes: 2^k + i * 2^(k-2) (i = 1 to 4).
+// Last class corresponds to kMaxSize = 1 << kMaxSizeLog.
+//
+// This structure of the size class map gives us:
+//   - Efficient table-free class-to-size and size-to-class functions.
+//   - Difference between two consequent size classes is between 14% and 25%
+//
+// This class also gives a hint to a thread-caching allocator about the amount
+// of chunks that need to be cached per-thread:
+//  - kMaxNumCachedHint is a hint for maximal number of chunks per size class.
+//    The actual number is computed in TransferBatch.
+//  - (1 << kMaxBytesCachedLog) is the maximal number of bytes per size class.

+// Sanitizer Coverage Controller for Trace PC Guard, Fuchsia-specific version.
+//
+// This Fuchsia-specific implementation uses the same basic scheme and the
+// same simple '.sancov' file format as the generic implementation.  The
+// difference is that we just produce a single blob of output for the whole
+// program, not a separate one per DSO.  We do not sort the PC table and do
+// not prune the zeros, so the resulting file is always as large as it
+// would be to report 100% coverage.  Implicit tracing information about
+// the address ranges of DSOs allows offline tools to split the one big
+// blob into separate files that the 'sancov' tool can understand.
+//
+// Unlike the traditional implementation that uses an atexit hook to write
+// out data files at the end, the results on Fuchsia do not go into a file
+// per se.  The 'coverage_dir' option is ignored.  Instead, they are stored
+// directly into a shared memory object (a Zircon VMO).  At exit, that VMO
+// is handed over to a system service that's responsible for getting the
+// data out to somewhere that it can be fed into the sancov tool (where and
+// how is not our problem).

+// sections with the same name before "$" are sorted alphabetically by the
+// string that comes after "$" and merged into one section. We take advantage
+// of this by putting data we want the size of into the middle (M) of a section,
+// by using the letter "M" after "$". We get the start of this data (ie:
+// __start_section_name) by making the start variable come at the start of the
+// section (using the letter A after "$"). We do the same to get the end of the
+// data by using the letter "Z" after "$" to make the end variable come after
+// the data. Note that because of our technique the address of the start
+// variable is actually the address of data that comes before our middle
+// section. We also need to prevent the linker from adding any padding. Each

+// When a lock event happens, the detector checks if the locks already held by
+// the current thread are reachable from the newly acquired lock.

+// The detector can handle only a fixed amount of simultaneously live locks
+// (a lock is alive if it has been locked at least once and has not been

+// `LocalAddressSpaceView` provides the local (i.e. target and current address
+// space are the same) implementation of the `AddressSpaceView` interface which
+// provides a simple interface to load memory from another process (i.e.
+// out-of-process)
+//
+// The `AddressSpaceView` interface requires that the type can be used as a
+// template parameter to objects that wish to be able to operate in an
+// out-of-process manner. In normal usage, objects are in-process and are thus
+// instantiated with the `LocalAddressSpaceView` type. This type is used to
+// load any pointers in instance methods. This implementation is effectively
+// a no-op. When an object is to be used in an out-of-process manner it is
+// instantiated with the `RemoteAddressSpaceView` type.
+//
+// By making `AddressSpaceView` a template parameter of an object, it can
+// change its implementation at compile time which has no run time overhead.
+// This also allows unifying in-process and out-of-process code which avoids
+// code duplication.

+// This module works by spawning a Linux task which then attaches to every
+// thread in the caller process with ptrace. This suspends the threads, and
+// PTRACE_GETREGS can then be used to obtain their register state. The callback
+// supplied to StopTheWorld() is run in the tracer task while the threads are
+// suspended.
+// The tracer task must be placed in a different thread group for ptrace to
+// work, so it cannot be spawned as a pthread. Instead, we use the low-level
+// clone() interface (we want to share the address space with the caller
+// process, so we prefer clone() over fork()).
+//
+// We don't use any libc functions, relying instead on direct syscalls. There
+// are two reasons for this:
+// 1. calling a library function while threads are suspended could cause a
+// deadlock, if one of the treads happens to be holding a libc lock;
+// 2. it's generally not safe to call libc functions from the tracer task,
+// because clone() does not set up a thread-local storage for it. Any
+// thread-local variables used by libc will be shared between the tracer task
+// and the thread which spawned it.

+// ----------------- A workaround for the absence of weak symbols --------------
+// We don't have a direct equivalent of weak symbols when using MSVC, but we can
+// use the /alternatename directive to tell the linker to default a specific
+// symbol to a specific value.
+// Take into account that this is a pragma directive for the linker, so it will
+// be ignored by the compiler and the function will be marked as UNDEF in the
+// symbol table of the resulting object file. The linker won't find the default
+// implementation until it links with that object file.
+// So, suppose we provide a default implementation "fundef" for "fun", and this
+// is compiled into the object file "test.obj" including the pragma directive.
+// If we have some code with references to "fun" and we link that code with
+// "test.obj", it will work because the linker always link object files.
+// But, if "test.obj" is included in a static library, like "test.lib", then the
+// liker will only link to "test.obj" if necessary. If we only included the
+// definition of "fun", it won't link to "test.obj" (from test.lib) because
+// "fun" appears as UNDEF, so it doesn't resolve the symbol "fun", and will
+// result in a link error (the linker doesn't find the pragma directive).
+// So, a workaround is to force linkage with the modules that include weak
+// definitions, with the following macro: WIN_FORCE_LINK()
+
+#define WIN_WEAK_ALIAS(Name, Default)                                          \
+  __pragma(comment(linker, "/alternatename:" WIN_SYM_PREFIX STRINGIFY(Name) "="\
+                                             WIN_SYM_PREFIX STRINGIFY(Default)))
+
+#define WIN_FORCE_LINK(Name)                                                   \
+  __pragma(comment(linker, "/include:" WIN_SYM_PREFIX STRINGIFY(Name)))
+
+#define WIN_EXPORT(ExportedName, Name)                                         \
+  __pragma(comment(linker, "/export:" WIN_EXPORT_PREFIX STRINGIFY(ExportedName)\
+                                  "=" WIN_EXPORT_PREFIX STRINGIFY(Name)))
+
+// We cannot define weak functions on Windows, but we can use WIN_WEAK_ALIAS()
+// which defines an alias to a default implementation, and only works when
+// linking statically.
+// So, to define a weak function "fun", we define a default implementation with
+// a different name "fun__def" and we create a "weak alias" fun = fun__def.
+// Then, users can override it just defining "fun".
+// We impose "extern "C"" because otherwise WIN_WEAK_ALIAS() will fail because
+// of name mangling.
+
+// Dummy name for default implementation of weak function.
+# define WEAK_DEFAULT_NAME(Name) Name##__def
+// Name for exported implementation of weak function.
+# define WEAK_EXPORT_NAME(Name) Name##__dll
+
+// Use this macro when you need to define and export a weak function from a
+// library. For example:
+//   WIN_WEAK_EXPORT_DEF(bool, compare, int a, int b) { return a > b; }
+# define WIN_WEAK_EXPORT_DEF(ReturnType, Name, ...)                            \
+  WIN_WEAK_ALIAS(Name, WEAK_DEFAULT_NAME(Name))                                \
+  WIN_EXPORT(WEAK_EXPORT_NAME(Name), Name)                                     \
+  extern "C" ReturnType Name(__VA_ARGS__);                                     \
+  extern "C" ReturnType WEAK_DEFAULT_NAME(Name)(__VA_ARGS__)
+
+// Use this macro when you need to import a weak function from a library. It
+// defines a weak alias to the imported function from the dll. For example:
+//   WIN_WEAK_IMPORT_DEF(compare)
+# define WIN_WEAK_IMPORT_DEF(Name)                                             \
+  WIN_WEAK_ALIAS(Name, WEAK_EXPORT_NAME(Name))
+
+// So, for Windows we provide something similar to weak symbols in Linux, with
+// some differences:
+// + A default implementation must always be provided.
+//
+// + When linking statically it works quite similarly. For example:
+//
+//   // libExample.cc
+//   WIN_WEAK_EXPORT_DEF(bool, compare, int a, int b) { return a > b; }
+//
+//   // client.cc
+//   // We can use the default implementation from the library:
+//   compare(1, 2);
+//   // Or we can override it:
+//   extern "C" bool compare (int a, int b) { return a >= b; }
+//
+//  And it will work fine. If we don't override the function, we need to ensure
+//  that the linker includes the object file with the default implementation.
+//  We can do so with the linker option "-wholearchive:".
+//
+// + When linking dynamically with a library (dll), weak functions are exported
+//  with "__dll" suffix. Clients can use the macro WIN_WEAK_IMPORT_DEF(fun)
+//  which defines a "weak alias" fun = fun__dll.
+//
+//   // libExample.cc
+//   WIN_WEAK_EXPORT_DEF(bool, compare, int a, int b) { return a > b; }
+//
+//   // client.cc
+//   WIN_WEAK_IMPORT_DEF(compare)
+//   // We can use the default implementation from the library:
+//   compare(1, 2);
+//   // Or we can override it:
+//   extern "C" bool compare (int a, int b) { return a >= b; }
+//
+//  But if we override the function, the dlls don't have access to it (which
+//  is different in linux). If that is desired, the strong definition must be
+//  exported and interception can be used from the rest of the dlls.
+//
+//   // libExample.cc
+//   WIN_WEAK_EXPORT_DEF(bool, compare, int a, int b) { return a > b; }
+//   // When initialized, check if the main executable defined "compare".
+//   int libExample_init() {
+//     uptr fnptr = __interception::InternalGetProcAddress(
+//         (void *)GetModuleHandleA(0), "compare");
+//     if (fnptr && !__interception::OverrideFunction((uptr)compare, fnptr, 0))
+//       abort();
+//     return 0;
+//   }
+//
+//   // client.cc
+//   WIN_WEAK_IMPORT_DEF(compare)
+//   // We override and export compare:
