From 55608e7dd1aa593944f967f2549564e4f42b654e Mon Sep 17 00:00:00 2001 From: lloyd Date: Thu, 31 May 2007 03:25:19 +0000 Subject: Write functions to handle loading and saving words a block at a time, taking into account endian differences. The current code does not take advantage of the knowledge of which endianness we are running on; an optimization suggested by Yves Jerschow is to use (unsafe) casts to speed up the load/store operations. This turns out to provide large performance increases (30% or more) in some cases. Even without the unsafe casts, this version seems to average a few percent faster, probably because the longer loading loops have been partially or fully unrolled. This also makes the code implementing low-level algorithms like ciphers and hashes a bit more succint. --- include/adler32.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'include/adler32.h') diff --git a/include/adler32.h b/include/adler32.h index 4a6975e90..4beb3bdb6 100644 --- a/include/adler32.h +++ b/include/adler32.h @@ -25,7 +25,7 @@ class Adler32 : public HashFunction void add_data(const byte[], u32bit); void final_result(byte[]); void hash(const byte[], u32bit); - u32bit S1, S2; + u16bit S1, S2; }; } -- cgit v1.2.3
