- * NOTE: If USE_CLZ_INTRINSIC is defined, then clz/bsr instructions will be
- * used for bit counting rather than the lookup table.  This will reduce the
- * memory footprint by 64k, which is important for some mobile applications
- * that create many isolated instances of libjpeg-turbo (web browsers, for
- * instance.)  This may improve performance on some mobile platforms as well.
- * This feature is enabled by default only on Arm processors, because some x86
- * chips have a slow implementation of bsr, and the use of clz/bsr cannot be
- * shown to have a significant performance impact even on the x86 chips that
- * have a fast implementation of it.  When building for Armv6, you can
- * explicitly disable the use of clz/bsr by adding -mthumb to the compiler
- * flags (this defines __thumb__).
