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. --- src/adler32.cpp | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) (limited to 'src/adler32.cpp') diff --git a/src/adler32.cpp b/src/adler32.cpp index b27fa247b..51f6cbea3 100644 --- a/src/adler32.cpp +++ b/src/adler32.cpp @@ -65,10 +65,7 @@ void Adler32::add_data(const byte input[], u32bit length) *************************************************/ void Adler32::final_result(byte output[]) { - output[0] = get_byte(2, S2); - output[1] = get_byte(3, S2); - output[2] = get_byte(2, S1); - output[3] = get_byte(3, S1); + store_be(output, S2, S1); clear(); } -- cgit v1.2.3
