Fix ZSTD_execSequence() performance regression
 2016-10-27 20:45:52 -07:00

10bfd0c0d5 Fix ZSTD_execSequence() performance regression 
Commit ae1cb3b3d0 caused the regression.
It is an instruction alignment issue, because if it is `U64 i` instead
of `U32 i`, the regression returns.  This patch fixes the regression
in gcc, but only gets some of the clang performance back.

Benchmarks:
Run on `silesia.tar`.  I only show levels 1-5 because the performance
regression was uniform across all levels.  I did one run on levels
1-19 and it looked good.

| Build | Level | Before | While | After |
|-------|-------|-------:|------:|------:|
| gcc   |     1 |  931.4 | 904.4 | 932.8 |
| gcc   |     2 |  849.1 | 822.6 | 851.2 |
| gcc   |     3 |  815.6 | 790.6 | 818.9 |
| gcc   |     4 |  794.1 | 770.7 | 798.0 |
| gcc   |     5 |  785.7 | 760.7 | 788.8 |
| clang |     1 |  705.5 | 683.2 | 693.8 |
| clang |     2 |  670.0 | 649.2 | 660.7 |
| clang |     3 |  659.6 | 639.8 | 651.4 |

eb7873a048 ZSTD_execSequence() accepts match in last 7 bytes 
The zstd reference compressor will not emit a match in the last 7
bytes of a block.  The decompressor will also not accept a match
in the last 7 bytes.  This patch makes the decompressor accept a
match in the last 7 bytes.
