d5a574c351 Corrected : a bug in compression function which could make it read beyond input buffer in some circumstances (issue 2). 
Many thanks for the detailed bug report.

8860e61b4f Removed LZ4_decode() function code. 
If you need to provide "isize" instead of "osize" to the decoder, please use LZ4_uncompress_unknownOutputSize(), which is safer.

075bf1349b Greatly 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.

6b798d5e40 New 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

0121f47e00 Corrected : demo program : "/" no longer a valid option trigger, in order to allow absolute path on *nix systems. 
Changed (minor) : demo program : differentiate error numbers between compression et decoding routines.
