Nick Terrell [Thu, 2 Mar 2017 01:51:56 +0000 (17:51 -0800)] 
Allow compressor to repeat Huffman tables

* Compressor saves most recently used Huffman table and reuses it
  if it produces better results.
* I attempted to preserve CPU usage profile.
  I intentionally left all of the existing heuristics in place.
  There is only a speed difference on the second block and later.
  When compressing large enough blocks (say >= 4 KiB) there is
  no significant difference in compression speed.
  Dictionary compression of one block is the same speed for blocks
  with literals <= 1 KiB, and after that the difference is not
  very significant.
* In the synthetic data, with blocks 10 KB or smaller, most blocks
  can't use repeated tables because the previous block did not
  contain a symbol that the current block contains.
  Once blocks are about 12 KB or more, most previous blocks have
  valid Huffman tables for the current block, and the compression
  ratio and decompression speed jumped.
* In silesia blocks as small as 4KB can frequently reuse the
  previous Huffman table (85%), but it isn't as profitable, and
  the previous Huffman table only gets used about 3% of the time.
* Microbenchmarks show that `HUF_validateCTable()` takes ~55 ns
  and `HUF_estimateCompressedSize()` takes ~35 ns.
  They are decently well optimized, the first versions took 90 ns
  and 120 ns respectively. `HUF_validateCTable()` could be twice as
  fast, if we cast the `HUF_CElt*` to a `U32*` and compare to 0.
  However, `U32` has an alignment of 4 instead of 2, so I think that
  might be undefined behavior.
* I've ran `zstreamtest` compiled normally, with UASAN and with MSAN
  for 4 hours each.

The worst case for the speed difference is a bunch of small blocks
in the same frame. I modified `bench.c` to compress the input in a
single frame but with blocks of the given block size, set by `-B`.

8 years agosolves warnings when compiling with global XXH_STATIC_LINKING_ONLY

solves warnings when compiling with global XXH_STATIC_LINKING_ONLY

XXH_STATIC_LINKING_ONLY protection macro is intended to be triggered just before the include.
The main idea is to keep this setting local :
user module shall explicitly understand and accept the static linking restriction
which becomes transparent when triggering the macro at project level.
Global definition also triggers redefinition warnings for user modules which do locally define the macro.

This new version compiles lib and cli without warning when the macro is set globally.
That's not a scenario to be recommended, since it trades a local effect for a global one,
but it was easy enough to provide from zstd side.
