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.

a201020317 Improved compression and decompression speed under GCC compiler

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.
