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.
|
2004-07-25 06:27:09 +02:00
|
|
|
The 64-bit implementations of POWER3 and POWER4 do a reasonable job
|
2013-01-07 18:20:53 +01:00
|
|
|
of handling unaligned load/stores that do not cross 32-byte boundaries.
|
2003-03-19 00:00:03 +01:00
|
|
|
|
|
|
|
Longer moves (>= 32-bytes) justify the effort to get at least the
|
|
|
|
destination doubleword (8-byte) aligned. Further optimization is
|
2013-01-07 18:20:53 +01:00
|
|
|
possible when both source and destination are doubleword aligned.
|
2003-03-19 00:00:03 +01:00
|
|
|
Each case has a optimized unrolled loop. */

In the short (0-8 byte) case no attempt is made to force alignment
|
2011-04-23 03:38:13 +02:00
|

|
of either source or destination. The hardware will handle the
|
|

|
unaligned load/stores with small delays for crossing 32- 64-byte, and
|
2004-07-25 06:27:09 +02:00
|
|
|
4096-byte boundaries. Since these short moves are unlikely to be
|
2011-04-23 03:38:13 +02:00
|
|
|
unaligned or cross these boundaries, the overhead to force
|
2004-07-25 06:27:09 +02:00
|
|
|
alignment is not justified.
|
2011-04-23 03:38:13 +02:00
|
|
|
|
2004-07-25 06:27:09 +02:00
|
|
|
The longer (9-31 byte) move is more likely to cross 32- or 64-byte
|
|
|
|
boundaries. Since only loads are sensitive to the 32-/64-byte
|
2011-04-23 03:38:13 +02:00
|
|
|
boundaries it is more important to align the source then the
|
2004-07-25 06:27:09 +02:00
|
|
|
destination. If the source is not already word aligned, we first
|
2011-04-23 03:38:13 +02:00
|
|
|
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.
|
2004-07-25 06:27:09 +02:00
|
|
|
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
|
2011-04-23 03:38:13 +02:00
|
|
|
case automatically with a small delay. */
