* Code review markups:Max Dymond2019-06-283-17/+18
| | | | | | - Correct use of CPPFLAGS - Detect allocation failure - Add a CHECK macro for failure

| * fullbench: ensure decompressionFunction and dName are initializedYann Collet2019-05-311-4/+14
| | | | | | | | Visual Studio seems to miss that they are necessarily initialized in the switch() { case: }
| * replaced while(1)Yann Collet2019-05-311-3/+2
| | | | | | | | | | by for (;;) just to please Visual Studio C4127 .
| * fullbench: added test scenario LZ4F_decompress_followHintYann Collet2019-05-311-13/+51
| | | | | | | | | | | | | | | | | | This emulates a streaming scenario, where the caller follows rigorously the srcSize hints provided as return value of LZ4F_decompress(). This is useful to show the issue in #714, where data is uselessly copied in a tmp buffer first.

| * | FAST_DEC_LOOP: only did offset check in specific condition.Chenxi Mao2019-05-311-2/+2
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When I did FAST_DEC_LOOP performance test, I found the offset check is much more than v1.8.3 You will see the condition check difference via lzbench with dickens test case. v1.8.3 34959 v.1.9.x 1055885 After investigate the code, we could see the difference. v.1.8.3 SKIP the condition check if if condition is true in: https://github.com/lz4/lz4/blob/v1.8.3/lib/lz4.c#L1463 AND below condition is true https://github.com/lz4/lz4/blob/v1.8.3/lib/lz4.c#L1478\ The offset check should be invoked. v1.9.3 The offset check code will be invoked in every loop which lead to downgrade. So the fix would be move this check to specific condition to avoid useless condition check. After this change, the call number is same as v1.8.3
