-/* The strategy of the memory functions is:
-
- 1. Copy bytes until the destination pointer is aligned.
-
- 2. Copy words in unrolled loops. If the source and destination
- are not aligned in the same way, use word memory operations,
- but shift and merge two read words before writing.
-
- 3. Copy the few remaining bytes.
-
- This is fast on processors that have at least 10 registers for
- allocation by GCC, and that can access memory at reg+const in one
- instruction.
-
- I made an "exhaustive" test of this memmove when I wrote it,
- exhaustive in the sense that I tried all alignment and length

- boundaries it is more important to align the source then the
- destination. If the source is not already word aligned, we first
- move 1-3 bytes as needed. Since we are only word aligned we don't
- use double word load/stores to insure that all loads are aligned.
- While the destination and stores may still be unaligned, this

- boundaries. So we want to use simple (unaligned) loads where
- posible but avoid them where we know the load would span a 32-byte
- boundary.
-
- At this point we know we have at least 29 (32-3) bytes to copy
- the src is unaligned. and we may cross at least one 32-byte
- boundary. Also we have the following regester values:
- r3 == adjusted dst, word aligned
- r4 == unadjusted src
- r5 == unadjusted len
- r9 == adjusted Word length
- r10 == src alignment (1-3)
- r12 == adjuested src, not aligned
- r31 == adjusted len
-
- First we need to copy word upto but not crossing the next 32-byte
- boundary. Then perform aligned loads just before and just after
- the boundary and use shifts and or to gernerate the next aligned
- word for dst. If more then 32 bytes remain we copy (unaligned src)
- the next 7 words and repeat the loop until less then 32-bytes
- remaim.
-
- Then if more then 4 bytes remain we again use aligned loads,
- shifts and or to generate the next dst word. We then process the
- remaining words using unaligned loads as needed. Finally we check
- if there more then 0 bytes (1-3) bytes remainting and use
- halfword and or byte load/stores to complete the copy.

-
- Memcpy handles short copies (< 32-bytes) using a binary move blocks
- (no loops) of lwz/stw. The tail (remaining 1-3) bytes is handled
- with the appropriate combination of byte and halfword load/stores.
- There is minimal effort to optimize the alignment of short moves.
- The 64-bit implementations of POWER3 and POWER4 do a reasonable job
- of handling unligned load/stores that do not cross 32-byte boundries.
-
- Longer moves (>= 32-bytes) justify the effort to get at least the
- destination doubleword (8-byte) aligned. Further optimization is
- posible when both source and destination are doubleword aligned.
- Each case has a optimized unrolled loop.
-
- For POWER6 unaligned loads will take a 20+ cycle hicup for any
- L1 cache miss that crosses a 32- or 128-byte boundary. Store
- is more forgiving and does not take a hicup until page or
- segment boundaries. So we require doubleword alignment for

-
- The longer (9-31 byte) move is more likely to cross 32- or 128-byte

- boundaries it is more important to align the source then the
- destination. If the source is not already word aligned, we first
- move 1-3 bytes as needed. Since we are only word aligned we don't
- use double word load/stores to insure that all loads are aligned.
- While the destination and stores may still be unaligned, this
- is only an issue for page (4096 byte boundary) crossing, which
- should be rare for these short moves. The hardware handles this
