fastmemcpybench.c used to benchmark fastmemcpy.h code from libvo.
|
||||
|
||||
Note: this code can not be used on PentMMX-PII because they contain
|
||||
a bug in rdtsc. For Intel processors since P6(PII) rdpmc should be used
|
||||
instead. For PIII it's disputable and seems bug was fixed but I don't
|

tested it.
