0c66a44d1b first working test program
measures :
- compression ratio with / without dictionary
- create one dictionary per block
- memory budget for dictionaries
- decompression speed, using one different dictionary per block

current limitations :
- only one file
- 4K blocks only
- automatic dictionary built with 4K size

dictionary can be selected on command line, with -D

9d6ed9def3 Merge fastCover into DictBuilder (#1274)
* Minor fix

* Run non-optimize FASTCOVER 5 times in benchmark

* Merge fastCover into dictBuilder

* Fix mixed declaration issue

* Add fastcover to symbol.c

* Add fastCover.c and cover.h to build

* Change fastCover.c to fastcover.c

* Change nbDmer to always read 8 bytes even when d=6

* Add skip=# argument to allow skipping dmers in computeFrequency in FASTCOVER

* Change default method of ZDICT_trainFromBuffer to ZDICT_optimizeTrainFromBuffer_fastCover

* Add dictType enum and fix bug about passing zParam when converting to coverParam

* Combine finalize and skip into a single parameter

* Update acceleration parameters and benchmark on 3 sample sets

* Change default splitPoint of FASTCOVER to 0.75 and benchmark first 3 sample sets

* Initialize variables outside of for loop in benchmark.c

* Update benchmark result for hg-manifest

* Remove cover.h from install-includes

* Add explanation of f

* Set default compression level for trainFromBuffer to 3

* Add assertion of fastCoverParams in DiB_trainFromFiles

* Add checkTotalCompressedSize function + some minor fixes

* Add test for multithreading fastCovr

* Initialize segmentFreqs in every FASTCOVER_selectSegment and move mutex_unnlock to end of COVER_best_finish

* Free segmentFreqs

* Initialize segmentFreqs before calling FASTCOVER_buildDictionary instead of in FASTCOVER_selectSegment

* Add FASTCOVER_MEMMULT

* Minor fix

* Update benchmarking result

bf30b9caf4 Add CXXFLAGS to ALL_LDFLAGS (#1178)
pzstd requires C++11, which older C++ standard libraries like libstdc++
as used on OS X 10.8 and earlier don't support. The user might address
this by setting "CXXFLAGS=-stdlib=libc++". This flag must be used both
at compile time and at link time. Asking the user to also put the flag
in LDFLAGS is undesirable because then the flag would also be used when
linking C code, which would be inappropriate.

2dbe408a49 Make the build reproducible
Whilst working on the Reproducible Builds effort [0], we noticed
that zstd could not be built reproducibly.

This is due to the manual page encoding the number of CPUs from the
build machine and thus varies across builds.

This was originally filed in Debian as #897904 [1].

00d52282d0 Use -pthread rather than -lpthread.
It can have other effects, such as pulling in extra libraries.  Without it,
riscv build fails with undefined reference to `__atomic_compare_exchange_1'.
