Title:
compilation error due to bug in savevm.c
Status in QEMU:
Fix Released
Bug description:
Since
302dfbeb21fc5154c24ca50d296e865a3778c7da
Add xbzrle_encode_buffer and xbzrle_decode_buffer functions
For performance we are encoding long word at a time.
For nzrun we use long-word-at-a-time NULL-detection tricks from strcmp():
using ((lword - 0x0101010101010101) & (~lword) & 0x8080808080808080) test
to find out if any byte in the long word is zero.
