-Configure Options
-==========================
-
-Below is the full set of options one can use to configure the libc build.
-An option can be given an explicit value on the CMake command line using
-the following syntax:
-
-.. code-block:: sh
-
-  $> cmake <other build options> -D<libc config option name>=<option value> <more options>
-
-For example:
-
-.. code-block:: sh
-
-  $> cmake <other build options> -DLIBC_CONF_PRINTF_DISABLE_FLOAT=ON <more options>
-
-See the main ``config/config.json``, and the platform and architecture specific
-overrides in ``config/<platform>/config.json`` and ``config/<platform>/<arch>/config.json,``
-to learn about the defaults for your platform and target.
-
-* **"codegen" options**
-    - ``LIBC_CONF_ENABLE_STRONG_STACK_PROTECTOR``: Enable -fstack-protector-strong to defend against stack smashing attack.
-    - ``LIBC_CONF_KEEP_FRAME_POINTER``: Keep frame pointer in functions for better debugging experience.
-* **"ctype" options**
-    - ``LIBC_CONF_CTYPE_SMALLER_ASCII``: Shrinks b36_char_to_int by assuming the character encoding is ASCII.
-* **"errno" options**
-    - ``LIBC_CONF_ERRNO_MODE``: The implementation used for errno, acceptable values are LIBC_ERRNO_MODE_DEFAULT, LIBC_ERRNO_MODE_UNDEFINED, LIBC_ERRNO_MODE_THREAD_LOCAL, LIBC_ERRNO_MODE_SHARED, LIBC_ERRNO_MODE_EXTERNAL, and LIBC_ERRNO_MODE_SYSTEM_INLINE.
-* **"fenv" options**
-    - ``LIBC_CONF_TRAP_ON_RAISE_FP_EXCEPT``: Trap with SIGFPE when feraiseexcept is called with unmasked floating point exceptions, similar to glibc's behavior.  This is currently working only on x86 with SSE.
-* **"general" options**
-    - ``LIBC_ADD_NULL_CHECKS``: Add nullptr checks in the library's implementations to some functions for which passing nullptr is undefined behavior.
-* **"math" options**
-    - ``LIBC_CONF_FREXP_INF_NAN_EXPONENT``: The value written back to the second parameter when calling frexp/frexpf/frexpl` with `+/-Inf`/`NaN` is unspecified.  Configure an explicit exp value for Inf/NaN inputs.
-    - ``LIBC_CONF_MATH_OPTIMIZATIONS``: Configure optimizations for math functions. Values accepted are LIBC_MATH_SKIP_ACCURATE_PASS, LIBC_MATH_SMALL_TABLES, LIBC_MATH_NO_ERRNO, LIBC_MATH_NO_EXCEPT, LIBC_MATH_FAST, and LIBC_MATH_INTERMEDIATE_COMP_IN_FLOAT.
-    - ``LIBC_CONF_MATH_USE_SYSTEM_FENV``: Use C standard fenv.h calls from the system libc instead our internal fenv implementations.
-* **"printf" options**
-    - ``LIBC_CONF_PRINTF_DISABLE_FIXED_POINT``: Disable printing fixed point values in printf and friends.
-    - ``LIBC_CONF_PRINTF_DISABLE_FLOAT``: Disable printing floating point values in printf and friends.
-    - ``LIBC_CONF_PRINTF_DISABLE_INDEX_MODE``: Disable index mode in the printf format string.
-    - ``LIBC_CONF_PRINTF_DISABLE_STRERROR``: Disable handling of %m to print strerror in printf and friends.
-    - ``LIBC_CONF_PRINTF_DISABLE_WIDE``: Disable handling wide characters for printf and friends.
-    - ``LIBC_CONF_PRINTF_DISABLE_WRITE_INT``: Disable handling of %n in printf format string.
-    - ``LIBC_CONF_PRINTF_FLOAT_TO_STR_NO_SPECIALIZE_LD``: Use the same mode for double and long double in printf.
-    - ``LIBC_CONF_PRINTF_FLOAT_TO_STR_USE_DYADIC_FLOAT``: Use dyadic float for faster and smaller but less accurate printf doubles.
-    - ``LIBC_CONF_PRINTF_FLOAT_TO_STR_USE_FLOAT320``: Use an alternative printf float implementation based on 320-bit floats
-    - ``LIBC_CONF_PRINTF_FLOAT_TO_STR_USE_MEGA_LONG_DOUBLE_TABLE``: Use large table for better printf long double performance.
-    - ``LIBC_CONF_PRINTF_RUNTIME_DISPATCH``: Use dynamic dispatch for the output mechanism to reduce code size.
-    - ``LIBC_COPT_PRINTF_DISABLE_BITINT``: Disable bitint length modifiers to reduce code size. Specifically the wNUM and wfNUM modifiers.
-* **"pthread" options**
-    - ``LIBC_CONF_RAW_MUTEX_DEFAULT_SPIN_COUNT``: Default number of spins before blocking if a mutex is in contention (default to 100).
-    - ``LIBC_CONF_RWLOCK_DEFAULT_SPIN_COUNT``: Default number of spins before blocking if a rwlock is in contention (default to 100).
-    - ``LIBC_CONF_TIMEOUT_ENSURE_MONOTONICITY``: Automatically adjust timeout to CLOCK_MONOTONIC (default to true). POSIX API may require CLOCK_REALTIME, which can be unstable and leading to unexpected behavior. This option will convert the real-time timestamp to monotonic timestamp relative to the time of call.
-* **"qsort" options**
-    - ``LIBC_CONF_QSORT_IMPL``: Configures sorting algorithm for qsort and qsort_r. Values accepted are LIBC_QSORT_QUICK_SORT, LIBC_QSORT_HEAP_SORT.
-* **"scanf" options**
-    - ``LIBC_CONF_SCANF_DISABLE_FLOAT``: Disable parsing floating point values in scanf and friends.
-    - ``LIBC_CONF_SCANF_DISABLE_INDEX_MODE``: Disable index mode in the scanf format string.
-* **"setjmp" options**
-    - ``LIBC_CONF_SETJMP_AARCH64_RESTORE_PLATFORM_REGISTER``: Make setjmp save the value of x18, and longjmp restore it. The AArch64 ABI delegates this register to platform ABIs, which can choose whether to make it caller-saved.
-* **"str_to_float" options**
-    - ``LIBC_CONF_STRTOFLOAT_DISABLE_CLINGER_FAST_PATH``: Disable Clinger's fast path for string to float conversion.
-    - ``LIBC_CONF_STRTOFLOAT_DISABLE_EISEL_LEMIRE``: Disable Eisel-Lemire algorithm for string to float conversion.
-    - ``LIBC_CONF_STRTOFLOAT_DISABLE_SIMPLE_DECIMAL_CONVERSION``: Disable simple decimal conversion for string to float conversion.
-* **"string" options**
-    - ``LIBC_CONF_FIND_FIRST_CHARACTER_IMPL``: Selects the implementation for find-first-character-related functions: 'element', 'word', 'clang_vector', or 'arch_vector'.
-    - ``LIBC_CONF_MEMSET_X86_USE_SOFTWARE_PREFETCHING``: Inserts prefetch for write instructions (PREFETCHW) for memset on x86 to recover performance when hardware prefetcher is disabled.
-    - ``LIBC_CONF_STRING_LENGTH_IMPL``: Selects the implementation for string-length: 'element', 'word', 'clang_vector', or 'arch_vector'.
-* **"threads" options**
-    - ``LIBC_CONF_THREAD_MODE``: The implementation used for Mutex, acceptable values are LIBC_THREAD_MODE_PLATFORM, LIBC_THREAD_MODE_SINGLE, and LIBC_THREAD_MODE_EXTERNAL.
-* **"time" options**
-    - ``LIBC_CONF_TIME_64BIT``: Force the size of time_t to 64 bits, even on platforms where compatibility considerations would otherwise make it 32-bit.
-* **"wctype" options**
-    - ``LIBC_CONF_WCTYPE_MODE``: The implementation used for wctype, acceptable values are LIBC_WCTYPE_MODE_ASCII and LIBC_WCTYPE_MODE_UTF8.
