- * ilog - Integer logarithm.
- *
- * ILOG_32() and ILOG_64() compute the minimum number of bits required to store
- * an unsigned 32-bit or 64-bit value without any leading zero bits.
- * This can also be thought of as the location of the highest set bit, with
- * counting starting from one (so that 0 returns 0, 1 returns 1, and 2**31
- * returns 32).
- * When the value is known to be non-zero ILOGNZ_32() and ILOGNZ_64() can
- * compile into as few as two instructions, one of which may get optimized out
- * later.
- * STATIC_ILOG_32 and STATIC_ILOG_64 allow computation on compile-time
- * constants, so other compile-time constants can be derived from them.
- *
- * Example:
- * #include <stdio.h>
- * #include <limits.h>
- * #include <ccan/ilog/ilog.h>
- *
- * int main(void){
- * int i;
- * printf("ILOG_32(0x%08X)=%i\n",0,ILOG_32(0));
- * for(i=1;i<=STATIC_ILOG_32(USHRT_MAX);i++){
- * uint32_t v;
- * v=(uint32_t)1U<<i-1;
- * //Here we know v is non-zero, so we can use ILOGNZ_32().
- * printf("ILOG_32(0x%08X)=%i\n",v,ILOGNZ_32(v));
- * }
- * return 0;
- * }
