89767cc280Small speed improvement (compression & decompression), Thanks Maciej Adamczyk for suggestion Fixed : LZ4_uncompress_unknownOutputSize(), now protected against a malicious attack type, where a crafted input deliberately attempts to make it read outside of input buffer.

8860e61b4fRemoved LZ4_decode() function code. If you need to provide "isize" instead of "osize" to the decoder, please use LZ4_uncompress_unknownOutputSize(), which is safer.

a201020317Improved compression and decompression speed under GCC compiler

075bf1349bGreatly improved compression and decompression speed, at the expense of some compression ratio. Most of the change is due to a modification in the performance parameter (HASH_LOG) now set to 12, to match Intel L1 cache processors. You can change it back to 17 to get back previous compression ratio. AMD users are invited to try HASH_LOG = 13, since AMD L1 cache is twice larger.

6b798d5e40New function : LZ4_uncompress : secure version which is safe against buffer overflow attacks New function : LZ4_uncompress_unknownOutputSize : secure but slower version which also guess the size of data to be decoded The demo file compression program (main.c) is updated to use these new functions LZ4_decode is still supported but in deprecated status, due to its vulnerability to malicious buffer overflow scenario
