Inline nodes in hash table nodes and eliminate key+value pointer overhead. Use SSE 4.2 accelerated node and string hashing when available. git-svn-id: http://svn.drobilla.net/sord/trunk@250 3d64ff67-21c5-427c-a301-fe4f08042e5a --- src/zix/digest.h | 39 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 src/zix/digest.h (limited to 'src/zix/digest.h') diff --git a/src/zix/digest.h b/src/zix/digest.h new file mode 100644 index 0000000..34ab376 --- /dev/null +++ b/src/zix/digest.h @@ -0,0 +1,39 @@ +/* + Copyright 2012 David Robillard + + Permission to use, copy, modify, and/or distribute this software for any + purpose with or without fee is hereby granted, provided that the above + copyright notice and this permission notice appear in all copies. + + THIS SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES + WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF + MERCHANTABILITY AND FITNESS.
