New Revision: 64099
URL: http://svn.boost.org/trac/boost/changeset/64099
Log:
adding test files and headers for calculating the necessary information about the pointer which is to be stuffed into a bitfield.
Added:

+ * 1.) Make sure that the mask for the pointer isn't 0.
+ * A.) if it is that means that NOTHING is being stored in the pointer
+ * and everything else can be ignroed (Not sure if this should be a
+ * PRECONDITION that causes a static_assertion or not).
+ * B.) Make sure the mask is the same size as a pointer.
+ * If it is NOT the same size as a pointer, then cause a static
+ * assertion.
+ *
+ * 2.) Determin the offset into the mask.
+ * A.) What is mean by this is that I need know which bits wihtin the
+ * mask that have value are respected as such and the ones which don't
+ * are able to be used for extra storage.
+ * B.) Summary: Look for leading zeros and look for trailing zeros.
+ * Those are the places which values can be stored within.
+ * C.) PRECONDITION: The offset must be less then or equal to the number
+ * of leading 0's within the value of the pointer.
+ * D.) Behavior in the case that there are leading zeros wihtin the
+ * mask and the offset is not the same as the amound of leading zeros
+ * within the mask. The zeros are treated as filler and the pointer is
+ * always stored relative to the mask provided.
+ *
+ *
+ * 3.) The offset of the storage location of the pointer shall be relative
+ * to the first 1 within the mask provided.
