* The value of HASHFRACTION is based on the minimum number of bytes
* of separation between two subroutine call points in the object code.
* Given MIN_SUBR_SEPARATION bytes of separation the value of
* HASHFRACTION is calculated as:
*
* HASHFRACTION = MIN_SUBR_SEPARATION / (2 * sizeof(short) - 1);
*
* For example, on the VAX, the shortest two call sequence is:
*
* calls $0,(r0)
* calls $0,(r0)
*
* which is separated by only three bytes, thus HASHFRACTION is
* calculated as:
*
* HASHFRACTION = 3 / (2 * 2 - 1) = 1
*
* Note that the division above rounds down, thus if MIN_SUBR_FRACTION
* is less than three, this algorithm will not work!
*
* In practice, however, call instructions are rarely at a minimal
* distance. Hence, we will define HASHFRACTION to be 2 across all
* architectures. This saves a reasonable amount of space for
* profiling data structures without (in practice) sacrificing
* any granularity.
