* cycle
*
* Principle of operation:
* First, note that L1 has a line-size of 64 bytes and L2 a line-size of 128 bytes.
* To avoid secondary misses in L2, we prefetch both source and destination with a line-size
* of 128 bytes. When both of these lines are in the L2 and the first half of the
* source line is in L1, we start copying the remaining words. The second half of the
* source line is prefetched in an earlier iteration, so that by the time we start
* accessing it, it's also present in the L1.
*
* We use a software-pipelined loop to control the overall operation. The pipeline
* has 2*PREFETCH_DIST+K stages. The first PREFETCH_DIST stages are used for prefetching
* source cache-lines. The second PREFETCH_DIST stages are used for prefetching destination
* cache-lines, the last K stages are used to copy the cache-line words not copied by
* the prefetches. The four relevant points in the pipelined are called A, B, C, D:
* p[A] is TRUE if a source-line should be prefetched, p[B] is TRUE if a destination-line
* should be prefetched, p[C] is TRUE if the second half of an L2 line should be brought
* into L1D and p[D] is TRUE if a cacheline needs to be copied.
*
* This all sounds very complicated, but thanks to the modulo-scheduled loop support,
* the resulting code is very regular and quite easy to follow (once you get the idea).
*
* As a secondary optimization, the first 2*PREFETCH_DIST iterations are implemented
* as the separate .prefetch_loop. Logically, this loop performs exactly like the
* main-loop (.line_copy), but has all known-to-be-predicated-off instructions removed,
* so that each loop iteration is faster (again, good for cached case).
*
* When reading the code, it helps to keep the following picture in mind:
*
* word 0 word 1
* +------+------+---
* | v[x] | t1 | ^
* | t2 | t3 | |
* | t4 | t5 | |
* | t6 | t7 | | 128 bytes
* | n[y] | t9 | | (L2 cache line)
* | t10 | t11 | |
* | t12 | t13 | |
* | t14 | t15 | v
* +------+------+---
*
* Here, v[x] is copied by the (memory) prefetch. n[y] is loaded at p[C]
* to fetch the second-half of the L2 cache line into L1, and the tX words are copied in
* an order that avoids bank conflicts.
