+# Cosmopolitan Template Library
+
+This package provides an STL alternative that's designed to:
+
+1. Compile 10x faster
+2. Solve the GDB debugger pain
+3. Symbol names should be simple
+4. Method names should be the same as STL
+5. Code belongs in .cpp files not in headers
+6. Depend on STL headers that aren't slow, e.g. `std::move`
+7. Use `stdckdint.h` and `__builtin_trap()` for better safety
+
+This code is experimental and mostly for Justine to save herself from
+the STL trainwreck. That doesn't mean cosmocc users aren't welcome to
+use tihs too. You shouldn't expect the design to not change later on.
+
+## Rationale
+
+The latency of the Standard Template Library (STL) has gotten out of
+control. Below you'll find a table documenting the last ten years of
+progress in the C++ language, measured on AMD Ryzen Threadripper PRO
+7995WX, the most expensive CPU there is.

+But wait, it gets better! Cosmo has a script that explains the
+complexity of transitive includes. Most Cosmopolitan headers are
+designed to not include other headers, e.g. `stdio.h`, `calls.h`,
+`runtime.h`, `thread.h`, etc. CTL is no exception to this rule.
+For example, here's the tool output for `#include <ctl/string.h>`:
+
+```
+$ tool/scripts/explain-deps.py ctl/string.h
+ctl/string.h
+        ctl/string_view.h
+```
+
+As we can see, `ctl/string.h` only includes `ctl/string_view.h` and the
+string view header includes literally nothing else.
+
+On the other hand, if we `#include <string>` for the LLVM libcxx header
+containing the `std::string` class, then the compiler needs to consider
+4,800 `#include` lines. Most of them are edges it'll discount since
+they've already been included but the sum total of files that get
+included is 694!

+/**
+ * @file demangle.c
+ * @brief Decode IA-64 C++ ABI style implementation.
+ *
+ * See the following IA-64 standard ABI(Itanium C++ ABI) references:
+ *
+ * - http://www.codesourcery.com/cxx-abi/abi.html#mangling
+ * - http://www.codesourcery.com/cxx-abi/abi-mangling.html
+ *
+ * This file has been forked and modified by Cosmopolitan Libc. We found
+ * it in the FreeBSD codebase, who got it from libcxxrt, who got it from
+ * libelftc on SourceForge. Here's what we changed:
+ *
+ * - We fixed a memory corruption bug (since upstreamed to libcxxrt)
+ *
+ * - We ensured slightly better conformance to libcxxabi test suites.
+ *
+ * - We renovated this module to not use malloc(). Our modified version
+ *   uses a new __demangle() API we defined with an strlcpy()-style. The
+ *   output buffer provided by the caller is used internally as a heap.
+ *
+ * - This is now the only C++ demangler that's asynchronous signal safe.
+ *   You now have the power to print C++ backtraces from signal handlers
+ *   without needing to block signals, because this code is reentrant,
+ *   and 100% lockless, and uses absolutely no writable static memory.
+ *   That makes it also great for kernel and embedded development.
+ *
+ * - We made it go 2x faster. It's almost as fast as libcxxabi now. The
+ *   lightweight Dennis Ritchie style demangle_malloc() implementation
+ *   helped. What also helped is introducing stack_str and strlcpy().
+ *
+ * - We made it use 3x less memory. This came with the tradeoff of
+ *   imposing limitations similar to embedded software. Rather than
+ *   using pointers, we use 16-bit indexes into a heap that can grow no
+ *   larger than 64kb. Please note that a buffer size of 20kb is more
+ *   than sufficient to pass all the libcxxabi test cases.
+ *
+ * - We made it have zero dependencies. If you compile this file with
+ *   GCC -ffreestanding flag then it won't link a single libc function.
+ *   Using heavyweight libc strings library functions doesn't make any
+ *   sense for a C++ demangler, which wokrs on strings a few chars long.
+ *
+ * - The floating point support is disabled by default, but it can be
+ *   re-enabled by commenting out `DEMANGLE_NO_FLOATING_POINT`. Although
+ *   Doing this will undermine the kernel / signal safety guarantees.
+ *
+ * Linking this demangler introduces at least 20kb of binary footprint.

+/**
+ * Decodes IA-64 C++ ABI style symbol.
+ *
+ * This function is designed to be safe to call from asynchronous signal
+ * handlers, since dynamic memory is allocated from the end of `buf`. As
+ * such it's important to provide a very generous amount of memory here.
+ *
+ * If you expect your symbols to be 100 characters long, you should pass
+ * at least 2000 bytes of buffer. If this function runs out of memory it
+ * will still create a NUL-terminated string in buf. On complete failure
+ * this will simply be the original string copied. On truncation it will
+ * be a partially copied result. In both cases, -1 is returned. The size
+ * of the output is only returned if this routine is fully succesful. To
+ * successfully cover nearly all the test cases from libcxxabi use 65536
+ * and to be able to print 99% of the symbols LLVM's libcxx.a, use 5632.
+ *
+ * It's important to call __is_mangled() before this, since some symbols
+ * have a special meaning; for example, "g" will return "__float128". It
+ * should be noted that this routine won't decode c++ symbols containing
+ * floating point numbers.
+ *
+ * **WARNING**: This implementation isn't as mature as __cxa_demangle().
+ *              It passes 27,124 out of the 29,798 libcxxabi test cases.
+ *
+ * @param buf is where nul-terminated output string is stored
+ * @param buflen should have at least 8192 bytes of memory
+ * @return bytes of output name or -1 upon error or truncation

- * @fileoverview Malloc Logging
- *
- * If you put the following in your main file:
- *
- *     __static_yoink("enable_memory_log");
- *
- * Then memory allocations with constant backtraces will be logged to
- * standard error. The columns printed are
- *
- *     MEM TID OP USAGE PTR OLD SIZE CALLER1 CALLER2 CALLER3 CALLER4
- *
- * delimited by spaces. For example, to see peak malloc usage:
- *
- *     ./myprog 2>log
- *     grep ^MEM log | sort -nk4 | tail -n10
- *
- * To see the largest allocations:
- *
- *     ./myprog 2>log
- *     grep ^MEM log | grep -v free | sort -nk7 | tail -n10

-/**
- * @brief Demangling routine.
- * ABI-mandated entry point in the C++ runtime library for demangling.
- *
- * @param __mangled_name A NUL-terminated character string
- * containing the name to be demangled.
- *
- * @param __output_buffer A region of memory, allocated with
- * malloc, of @a *__length bytes, into which the demangled name is
- * stored.  If @a __output_buffer is not long enough, it is
- * expanded using realloc.  @a __output_buffer may instead be null;
- * in that case, the demangled name is placed in a region of memory
- * allocated with malloc.
- *
- * @param __length If @a __length is non-null, the length of the
- * buffer containing the demangled name is placed in @a *__length.
- *
- * @param __status If @a __status is non-null, @a *__status is set to
- * one of the following values:
- *  0: The demangling operation succeeded.
- * -1: A memory allocation failure occurred.
- * -2: @a mangled_name is not a valid name under the C++ ABI mangling rules.
- * -3: One of the arguments is invalid.
- *
- * @return A pointer to the start of the NUL-terminated demangled
- * name, or a null pointer if the demangling fails.  The caller is
- * responsible for deallocating this memory using @c free.
- *
- * The demangling is performed using the C++ ABI mangling rules,
- * with GNU extensions. For example, this function is used in
- * __gnu_cxx::__verbose_terminate_handler.
- *
- * See https://gcc.gnu.org/onlinedocs/libstdc++/manual/ext_demangling.html
- * for other examples of use.
- *
- * @note The same demangling functionality is available via
- * libiberty (@c <libiberty/demangle.h> and @c libiberty.a) in GCC
- * 3.1 and later, but that requires explicit installation (@c
- * --enable-install-libiberty) and uses a different API, although
- * the ABI is unchanged.

 LOCAL CHANGES
 
+  - Wrote __config_site
+  - Add __COSMOPOLITAN__ when appropriate
+  - Kludged (and probably broke) awful `cerr` feature
   - Break apart locale.cpp due to its outrageous build times
+  - Suppress -Wattribute sometimes due to __always_inline__ hack

+// Libc++ is shipped by various vendors. In particular, it is used as a system
+// library on macOS, iOS and other Apple platforms. In order for users to be
+// able to compile a binary that is intended to be deployed to an older version
+// of a platform, Clang provides availability attributes [1]. These attributes
+// can be placed on declarations and are used to describe the life cycle of a
+// symbol in the library.
+//
+// The main goal is to ensure a compile-time error if a symbol that hasn't been
+// introduced in a previously released library is used in a program that targets
+// that previously released library. Normally, this would be a load-time error
+// when one tries to launch the program against the older library.
+//
+// For example, the filesystem library was introduced in the dylib in macOS 10.15.
+// If a user compiles on a macOS 10.15 host but targets macOS 10.13 with their
+// program, the compiler would normally not complain (because the required
+// declarations are in the headers), but the dynamic loader would fail to find
+// the symbols when actually trying to launch the program on macOS 10.13. To
+// turn this into a compile-time issue instead, declarations are annotated with
+// when they were introduced, and the compiler can produce a diagnostic if the
+// program references something that isn't available on the deployment target.
+//
+// This mechanism is general in nature, and any vendor can add their markup to
+// the library (see below). Whenever a new feature is added that requires support
+// in the shared library, two macros are added below to allow marking the feature
+// as unavailable:
+// 1. A macro named `_LIBCPP_AVAILABILITY_HAS_NO_<feature>` which must be defined
+//    exactly when compiling for a target that doesn't support the feature.
+// 2. A macro named `_LIBCPP_AVAILABILITY_<feature>`, which must always be defined
+//    and must expand to the proper availability attribute for the platform.
+//
+// When vendors decide to ship the feature as part of their shared library, they
+// can update these macros appropriately for their platform, and the library will
+// use those to provide an optimal user experience.
+//
+// Furthermore, many features in the standard library have corresponding
+// feature-test macros. The `_LIBCPP_AVAILABILITY_HAS_NO_<feature>` macros
+// are checked by the corresponding feature-test macros generated by
+// generate_feature_test_macro_components.py to ensure that the library
+// doesn't announce a feature as being implemented if it is unavailable on
+// the deployment target.
+//
+// Note that this mechanism is disabled by default in the "upstream" libc++.
+// Availability annotations are only meaningful when shipping libc++ inside
+// a platform (i.e. as a system library), and so vendors that want them should
+// turn those annotations on at CMake configuration time.

+// This macro marks a symbol as being hidden from libc++'s ABI. This is achieved
+// on two levels:
+// 1. The symbol is given hidden visibility, which ensures that users won't start exporting
+//    symbols from their dynamic library by means of using the libc++ headers. This ensures
+//    that those symbols stay private to the dynamic library in which it is defined.
+//
+// 2. The symbol is given an ABI tag that changes with each version of libc++. This ensures
+//    that no ODR violation can arise from mixing two TUs compiled with different versions
+//    of libc++ where we would have changed the definition of a symbol. If the symbols shared
+//    the same name, the ODR would require that their definitions be token-by-token equivalent,
+//    which basically prevents us from being able to make any change to any function in our
+//    headers. Using this ABI tag ensures that the symbol name is "bumped" artificially at
+//    each release, which lets us change the definition of these symbols at our leisure.
+//    Note that historically, this has been achieved in various ways, including force-inlining
+//    all functions or giving internal linkage to all functions. Both these (previous) solutions
+//    suffer from drawbacks that lead notably to code bloat.
+//
+// Note that we use _LIBCPP_EXCLUDE_FROM_EXPLICIT_INSTANTIATION to ensure that we don't depend
+// on _LIBCPP_HIDE_FROM_ABI methods of classes explicitly instantiated in the dynamic library.
+//
+// Also note that the _LIBCPP_HIDE_FROM_ABI_VIRTUAL macro should be used on virtual functions
+// instead of _LIBCPP_HIDE_FROM_ABI. That macro does not use an ABI tag. Indeed, the mangled
+// name of a virtual function is part of its ABI, since some architectures like arm64e can sign
+// the virtual function pointer in the vtable based on the mangled name of the function. Since
+// we use an ABI tag that changes with each released version, the mangled name of the virtual
+// function would change, which is incorrect. Note that it doesn't make much sense to change
+// the implementation of a virtual function in an ABI-incompatible way in the first place,
+// since that would be an ABI break anyway. Hence, the lack of ABI tag should not be noticeable.
+//
+// TODO: We provide a escape hatch with _LIBCPP_NO_ABI_TAG for folks who want to avoid increasing
+//       the length of symbols with an ABI tag. In practice, we should remove the escape hatch and

+// the lookups are not expected to be used often. An alternative would be to
+// convert all elements during construction.
+//
+// The elements of the retargets context are only used when an underlying
+// formatter uses a locale specific formatting or an formatting argument is
+// part for the format spec. For example
+//   format("{:256:{}}", input, 8);
+// Here the width of an element in input is determined dynamically.
+// Note when the top-level element has no width the retargeting is not needed.

+/// - The "overrides" in [format.string.std]/12
+///
+/// The format of EastAsianWidth.txt is two fields separated by a semicolon.
+/// Field 0: Unicode code point value or range of code point values
+/// Field 1: East_Asian_Width property, consisting of one of the following values:
+///         "A", "F", "H", "N", "Na", "W"
+///  - All code points, assigned or unassigned, that are not listed
+///      explicitly are given the value "N".
+///  - The unassigned code points in the following blocks default to "W":
+///         CJK Unified Ideographs Extension A: U+3400..U+4DBF
+///         CJK Unified Ideographs:             U+4E00..U+9FFF
+///         CJK Compatibility Ideographs:       U+F900..U+FAFF
+///  - All undesignated code points in Planes 2 and 3, whether inside or
+///      outside of allocated blocks, default to "W":
+///         Plane 2:                            U+20000..U+2FFFD

+/// The table is similar to the table
+///  __extended_grapheme_custer_property_boundary::__entries
+/// which explains the details of these classes. The only difference is this
+/// table lacks a property, thus having more bits available for the size.
+///
+/// The maximum code point that has an estimated width of 2 is U+3FFFD. This
+/// value can be encoded in 18 bits. Thus the upper 3 bits of the code point
+/// are always 0. These 3 bits are used to enlarge the offset range. This
+/// optimization reduces the table in Unicode 15 from 184 to 104 entries,
+/// saving 320 bytes.
+///
+/// The data has 2 values:
+/// - bits [0, 13] The size of the range, allowing 16384 elements.
+/// - bits [14, 31] The lower bound code point of the range. The upper bound of
+///   the range is lower bound + size.

+// In C++20, when a reverse iterator wraps certain C++20-hostile iterators, calling comparison operators on it will
+// result in a compilation error. However, calling comparison operators on the pristine hostile iterator is not
+// an error. Thus, we cannot use reverse_iterators in the implementation of an algorithm that accepts a
+// C++20-hostile iterator. This class is an internal workaround -- it is a copy of reverse_iterator with
+// tweaks to make it support hostile iterators.
+//
+// A C++20-hostile iterator is one that defines a comparison operator where one of the arguments is an exact match
+// and the other requires an implicit conversion, for example:
+//   friend bool operator==(const BaseIter&, const DerivedIter&);
+//
+// C++20 rules for rewriting equality operators create another overload of this function with parameters reversed:
+//   friend bool operator==(const DerivedIter&, const BaseIter&);
+//
+// This creates an ambiguity in overload resolution.
+//
+// Clang treats this ambiguity differently in different contexts. When operator== is actually called in the function
+// body, the code is accepted with a warning. When a concept requires operator== to be a valid expression, however,
+// it evaluates to false. Thus, the implementation of reverse_iterator::operator== can actually call operator== on its
+// base iterators, but the constraints on reverse_iterator::operator== prevent it from being considered during overload
+// resolution. This class simply removes the problematic constraints from comparison functions.

+// Let i:len denote a counted interval of length n starting at i.  s denotes a generalized-sum value.
+// Expected actions of the functors are:
+//     reduce(i,len) -> s  -- return reduction value of i:len.
+//     combine(s1,s2) -> s -- return merged sum
+//     apex(s) -- do any processing necessary between reduce and scan.
+//     scan(i,len,initial) -- perform scan over i:len starting with initial.
+// The initial range 0:n is partitioned into consecutive subranges.
+// reduce and scan are each called exactly once per subrange.
+// Thus callers can rely upon side effects in reduce.
+// combine must not throw an exception.
+// apex is called exactly once, after all calls to reduce and before all calls to scan.
+// For example, it's useful for allocating a __buffer used by scan but whose size is the sum of all reduction values.
+// T must have a trivial constructor and destructor.

+    //   integer, where a large positive value of the unsigned integer corresponds to a negative value in the signed
+    //   integer type), the value of `To` that results from a bitwise copy of `From` is the same what would be produced

+    //   `1` to `float` results in a very small less-than-one value, unlike built-in assignment that produces `1.0`
+    //   (fails #2);
+    // - booleans normally use only a single bit of their object representation; bit-casting an integer to a boolean
+    //   will result in a boolean object with an incorrect representation, which is undefined behavior (fails #2).
+    //   Bit-casting from a boolean into an integer, however, is valid;
+    // - enumeration types may have different ranges of possible values (fails #1);
+    // - for pointers, it is not guaranteed that pointers to different types use the same set of values to represent
+    //   addresses, and the conversion results are explicitly unspecified for types with different alignments
+    //   (fails #1);
+    // - for structs and unions it is impossible to determine whether the set of values of one of them is a subset of

+// tell us whether that's the case for arbitrary types, so we can only do this for known types. Specifically, these are
+// currently unsigned integer types with a sizeof(T) == 1.
+//
+// bool is trivially lexicographically comparable, because e.g. false <=> true is valid code. Furthermore, the standard
+// says that [basic.fundamental] "Type bool is a distinct type that has the same object representation, value
+// representation, and alignment requirements as an implementation-defined unsigned integer type. The values of type
+// bool are true and false."
+// This means that bool has to be unsigned and has exactly two values. This means that having anything other than the
+// `true` or `false` value representations in a bool is UB.
+//
+// The following types are not trivially lexicographically comparable:
+// signed integer types: `char(-1) < char(1)`, but memcmp compares `unsigned char`s
+// unsigned integer types with sizeof(T) > 1: depending on the endianness, the LSB might be the first byte to be
+//                                            compared. This means that when comparing unsigned(129) and unsigned(2)
+//                                            using memcmp(), the result would be that 2 > 129.

+// __exception_guard is a helper class for writing code with the strong exception guarantee.
+//
+// When writing code that can throw an exception, one can store rollback instructions in an
+// exception guard so that if an exception is thrown at any point during the lifetime of the
+// exception guard, it will be rolled back automatically. When the exception guard is done, one
+// must mark it as being complete so it isn't rolled back when the exception guard is destroyed.
+//
+// Exception guards are not default constructible, they can't be copied or assigned to, but
+// they can be moved around for convenience.
+//
+// __exception_guard is a no-op in -fno-exceptions mode to produce better code-gen. This means
+// that we don't provide the strong exception guarantees. However, Clang doesn't generate cleanup
+// code with exceptions disabled, so even if we wanted to provide the strong exception guarantees
+// we couldn't. This is also only relevant for constructs with a stack of
+// -fexceptions > -fno-exceptions > -fexceptions code, since the exception can't be caught where
+// exceptions are disabled. While -fexceptions > -fno-exceptions is quite common
+// (e.g. libc++.dylib > -fno-exceptions), having another layer with exceptions enabled seems a lot
+// less common, especially one that tries to catch an exception through -fno-exceptions code.
+//
+// __exception_guard can help greatly simplify code that would normally be cluttered by
+// `#if _LIBCPP_HAS_NO_EXCEPTIONS`. For example:
+//
+//    template <class Iterator, class Size, class OutputIterator>
+//    Iterator uninitialized_copy_n(Iterator iter, Size n, OutputIterator out) {
+//        typedef typename iterator_traits<Iterator>::value_type value_type;
+//        __exception_guard guard([start=out, &out] {
+//            std::destroy(start, out);
+//        });
+//
+//        for (; n > 0; ++iter, ++out, --n) {
+//            ::new ((void*)std::addressof(*out)) value_type(*iter);
+//        }
+//        guard.__complete();
+//        return out;
+//    }

+// For general precision, we can use lookup tables to avoid performing trial formatting.
+
+// For a simple example, imagine counting the number of digits D in an integer, and needing to know
+// whether D is less than 3, equal to 3/4/5/6, or greater than 6. We could use a lookup table:
+// D | Largest integer with D digits
+// 2 |      99
+// 3 |     999
+// 4 |   9'999
+// 5 |  99'999
+// 6 | 999'999
+// 7 | table end
+// Looking up an integer in this table with lower_bound() will work:
+// * Too-small integers, like 7, 70, and 99, will cause lower_bound() to return the D == 2 row. (If all we care
+//   about is whether D is less than 3, then it's okay to smash the D == 1 and D == 2 cases together.)
+// * Integers in [100, 999] will cause lower_bound() to return the D == 3 row, and so forth.
+// * Too-large integers, like 1'000'000 and above, will cause lower_bound() to return the end of the table. If we
+//   compute D from that index, this will be considered D == 7, which will activate any "greater than 6" logic.
+
+// Floating-point is slightly more complicated.
+
+// The ordinary lookup tables are for X within [-5, 38] for float, and [-5, 308] for double.
+// (-5 absorbs too-negative exponents, outside the P > X >= -4 criterion. 38 and 308 are the maximum exponents.)
+// Due to the P > X condition, we can use a subset of the table for X within [-5, P - 1], suitably clamped.
+
+// When P is small, rounding can affect X. For example:
+// For P == 1, the largest double with X == 0 is: 9.4999999999999982236431605997495353221893310546875
+// For P == 2, the largest double with X == 0 is: 9.949999999999999289457264239899814128875732421875
+// For P == 3, the largest double with X == 0 is: 9.9949999999999992184029906638897955417633056640625
+
+// Exponent adjustment is a concern for P within [1, 7] for float, and [1, 15] for double (determined via
+// brute force). While larger values of P still perform rounding, they can't trigger exponent adjustment.
+// This is because only values with repeated '9' digits can undergo exponent adjustment during rounding,
+// and floating-point granularity limits the number of consecutive '9' digits that can appear.
+
+// So, we need special lookup tables for small values of P.
+// These tables have varying lengths due to the P > X >= -4 criterion. For example:
+// For P == 1, need table entries for X: -5, -4, -3, -2, -1, 0
+// For P == 2, need table entries for X: -5, -4, -3, -2, -1, 0, 1
+// For P == 3, need table entries for X: -5, -4, -3, -2, -1, 0, 1, 2
+// For P == 4, need table entries for X: -5, -4, -3, -2, -1, 0, 1, 2, 3
+
+// We can concatenate these tables for compact storage, using triangular numbers to access them.
+// The table for P begins at index (P - 1) * (P + 10) / 2 with length P + 5.
+
+// For both the ordinary and special lookup tables, after an index I is returned by lower_bound(), X is I - 5.
+
+// We need to special-case the floating-point value 0.0, which is considered to have X == 0.
+// Otherwise, the lookup tables would consider it to have a highly negative X.
+
+// Finally, because we're working with positive floating-point values,
+// representation comparisons behave identically to floating-point comparisons.
+
+// The following code generated the lookup tables for the scientific exponent X. Don't remove this code.

+// We need a 64x128-bit multiplication and a subsequent 128-bit shift.
+// Multiplication:
+//   The 64-bit factor is variable and passed in, the 128-bit factor comes
+//   from a lookup table. We know that the 64-bit factor only has 55
+//   significant bits (i.e., the 9 topmost bits are zeros). The 128-bit
+//   factor only has 124 significant bits (i.e., the 4 topmost bits are
+//   zeros).
+// Shift:
+//   In principle, the multiplication result requires 55 + 124 = 179 bits to
+//   represent. However, we then shift this value to the right by __j, which is
+//   at least __j >= 115, so the result is guaranteed to fit into 179 - 115 = 64
+//   bits. This means that we only need the topmost 64 significant bits of
+//   the 64x128-bit multiplication.
+//
+// There are several ways to do this:
+// 1. Best case: the compiler exposes a 128-bit type.
+//    We perform two 64x64-bit multiplications, add the higher 64 bits of the
+//    lower result to the higher result, and shift by __j - 64 bits.
+//
+//    We explicitly cast from 64-bit to 128-bit, so the compiler can tell
+//    that these are only 64-bit inputs, and can map these to the best
+//    possible sequence of assembly instructions.
+//    x64 machines happen to have matching assembly instructions for
+//    64x64-bit multiplications and 128-bit shifts.
+//
+// 2. Second best case: the compiler exposes intrinsics for the x64 assembly
+//    instructions mentioned in 1.
+//
+// 3. We only have 64x64 bit instructions that return the lower 64 bits of
+//    the result, i.e., we have to use plain C.
+//    Our inputs are less than the full width, so we have three options:
+//    a. Ignore this fact and just implement the intrinsics manually.
+//    b. Split both into 31-bit pieces, which guarantees no internal overflow,
+//       but requires extra work upfront (unless we change the lookup table).
+//    c. Split only the first factor into 31-bit pieces, which also guarantees
+//       no internal overflow, but requires extra work since the intermediate
+//       results are not perfectly aligned.

+// symbol, it is given hidden visibility instead and the non-unique bit is set.
+// Otherwise, types declared with hidden visibility are always considered to have
