124 * Table size depends on STRICT_ALIGNMENT and whether or not endian-
125 * specific ROTATE macro is defined. If STRICT_ALIGNMENT is not
126 * defined, which is normally the case on x86[_64] CPUs, the table is
127 * 4KB large unconditionally. Otherwise if ROTATE is defined, the
128 * table is 2KB large, and otherwise - 16KB. 2KB table requires a
129 * whole bunch of additional rotations, but I'm willing to "trade,"
130 * because 16KB table certainly trashes L1 cache. I wish all CPUs
131 * could handle unaligned load as 4KB table doesn't trash the cache,
132 * nor does it require additional rotations.
135 * Note that every Cn macro expands as two loads: one byte load and
136 * one quadword load. One can argue that that many single-byte loads
137 * is too excessive, as one could load a quadword and "milk" it for
138 * eight 8-bit values instead. Well, yes, but in order to do so *and*
139 * avoid excessive loads you have to accomodate a handful of 64-bit
140 * values in the register bank and issue a bunch of shifts and mask.
141 * It's a tradeoff: loads vs. shift and mask in big register bank[!].
142 * On most CPUs eight single-byte loads are faster and I let other
143 * ones to depend on smart compiler to fold byte loads if beneficial.
144 * Hand-coded assembler would be another alternative:-)
