+ * Name:        MLD_CONFIG_NO_ASM
+ *
+ * Description: If this option is set, mldsa-native will be built without
+ *              use of native code or inline assembly.
+ *
+ *              By default, inline assembly is used to implement value barriers.
+ *              Without inline assembly, mldsa-native will use a global volatile
+ *              'opt blocker' instead; see ct.h.
+ *
+ *              Inline assembly is also used to implement a secure zeroization
+ *              function on non-Windows platforms. If this option is set and
+ *              the target platform is not Windows, you MUST set
+ *              MLD_CONFIG_CUSTOM_ZEROIZE and provide a custom zeroization
+ *              function.
+ *
+ *              If this option is set, MLD_CONFIG_USE_NATIVE_BACKEND_FIPS202 and
+ *              and MLD_CONFIG_USE_NATIVE_BACKEND_ARITH will be ignored, and no
+ *              native backends will be used.
