Carl Woffenden 3eaa525138 Fixed clash when projects are already using xxHash
Undefing XXH_* macros allows the `.c` to build standalone without clashes. Removing `xxhash.c` and only including the header is the correct usage (according to `XXH_PRIVATE_API`).

Carl Woffenden edd9a07322 Code replicated in compression and decompression moved to shared headers
`CHECK_F` macro moved to `error_private.h` (shared between `fse_compress.c` and `fse_decompress.c`). `ZSTD_limitCopy()` moved to `zstd_internal.h` (shared between `zstd_compress.c` and `zstd_decompress.c`). Erroneous build artefact `zstd.h` removed from repo.

Carl Woffenden 7c420344d2 Single-file decoder script can now (optionally) create an encoder
To complement the single-file decoder a new script was added to create an amalgamated single-file of all of the Zstd source, along with examples and (simple) tests.

Fixes decompressor when using -Wshorten-64-to-32 (#2062)
Spotted on iOS when building with `-Wshorten-64-to-32` (since `__builtin_expect` returns a `long`).

Nick Terrell ef9e6fe227 [test] Fix playTests.sh with space in binary path
playTests.sh didn't work when `ZSTD_BIN` or `DATAGEN_BIN` had a space in
the path name. This happens for me because I split the cmake build
directory by compiler name, like "Clang 9.0.0".

The fix is to replace all instances of `$ZSTD` with the `zstd()`
function, and the replace `$DATAGEN` with `datagen()`. This will allow
us to change how we call zstd/datagen in the future without having to
change every callsite.

Nick Terrell 1f144351b7 [test] Add a test that checks for valid copyright and licenses
Tests all `.h`, `.c`, `.py`, and `Makefile` files for valid copyright
and license lines. Excludes a small number of exceptions (threading, and
divsufsort).

* Copyright does not contains `present`
* Copyright contains `Facebook, Inc`
* Copyright contains the current year
* License contains exactly the lines we expect
2020-03-26 17:02:09 -07:00
Nick Terrell ac58c8d720 Fix copyright and license lines
* All copyright lines now have -2020 instead of -present
* All copyright lines include "Facebook, Inc"
* All licenses are now standardized

The copyright in `threading.{h,c}` is not changed because it comes from
zstdmt.

The copyright and license of `divsufsort.{h,c}` is not changed.

Merge pull request #2050 from terrelln/align
Align decompress sequences loop to 32+16 bytes
2020-03-24 11:42:59 -07:00
Nick Terrell 8d0ee37ac0 Align decompress sequences loop to 32+16 bytes
The alignment is added before the loop, so this shouldn't hurt
performance in any case. The only way it hurts is if there is already
performance instability, and we force it to be stable but in the bad
case.

This consistently gets us into the good case with gcc-{7,8,9} on an
Intel i9-9900K and clang-9. gcc-5 is 5% worse than its best case but has
stable performance. We get consistently good behavior on my Macbook Pro
compiled with both clang and gcc-8. It ends up in the 50% from DSB and
50% from MITE case, but the performance is the same as the 85% DSB case,
so thats fine.
