- * The table consists of 37 subtables, each subtable contains 64 affine points.
- * The affine points are encoded as eight uint64's, four for the x coordinate
- * and four for the y. Both values are in little-endian order.
- *
- * There are 37 tables because a signed, 6-bit wNAF form of the scalar is used
- * and ceil(256/(6 + 1)) = 37. Within each table there are 64 values because
- * the 6-bit wNAF value can take 64 values, ignoring the sign bit, which is
- * implemented by performing a negation of the affine point when required.
- *
- * We would like to align it to 2MB in order to increase the chances of using a
- * large page but that appears to lead to invalid ELF files being produced. */
