66 * \def MBEDTLS_NO_UDBL_DIVISION
67 *
68 * The platform lacks support for double-width integer division (64-bit
69 * division on a 32-bit platform, 128-bit division on a 64-bit platform).
70 *
71 * Used in:
72 * include/mbedtls/bignum.h
73 * library/bignum.c
74 *
75 * The bignum code uses double-width division to speed up some operations.
76 * Double-width division is often implemented in software that needs to
77 * be linked with the program. The presence of a double-width integer
78 * type is usually detected automatically through preprocessor macros,
79 * but the automatic detection cannot know whether the code needs to
80 * and can be linked with an implementation of division for that type.
81 * By default division is assumed to be usable if the type is present.
82 * Uncomment this option to prevent the use of double-width division.
83 *
84 * Note that division for the native integer type is always required.
85 * Furthermore, a 64-bit type is always required even on a 32-bit
86 * platform, but it need not support multiplication or division. In some
87 * cases it is also desirable to disable some double-width operations. For
88 * example, if double-width division is implemented in software, disabling
89 * it can reduce code size in some embedded targets.

101 * Some parts of the library may use multiplication of two unsigned 32-bit
102 * operands with a 64-bit result in order to speed up computations. On some
103 * platforms, this is not available in hardware and has to be implemented in
104 * software, usually in a library provided by the toolchain.

106 * Sometimes it is not desirable to have to link to that library. This option
107 * removes the dependency of that library on platforms that lack a hardware
108 * 64-bit multiplier by embedding a software implementation in Mbed TLS.
