Contributions to the library are gladly accepted.
2+
3+
The main development happens in https://github.com/p12tic/libsimdpp repository.
4+
5+
If you don't have time to submit a bug fix, please open an issue report on
6+
GitHub so at least the problem is known. The same applies to improvements -
7+
don't hesitate to open feature request so that the design of new APIs could
8+
take your use case into account.

Documentation
11+
-------------
12+
13+
The documentation is written on a MediaWiki instance which is currently private.

If you find a problem in the documentation, please open an issue with a link to
15+
the page in question.

17+
Code changes
18+
------------
19+
20+
Please test your code changes by running the following:
21+
22+
```
23+
mkdir build
24+
cd build
25+
cmake ..
26+
27+
# on Linux / macOS
28+
make check -j8
29+
30+
# on Windows
31+
cmake --build . --target check
32+
```
33+
34+
Please use the `dev` branch as a target for pull requests. The reason for this
35+
is that the public continuous integration services used by the library cover
36+
only SSE2-AVX2 instruction sets. The rest are periodically tested on a private
37+
test farm. Due to the number of tested compilers and library configurations
38+
this testing is usually done only on each merge from the `dev` branch to
39+
the `master` branch.
40+
41+
Code style
42+
----------
43+
44+
C-style pointer casts are discouraged, use reinterpret_cast for that. For
45+
non-pointer types C-style casts are preferred over static_cast or constructor.

What's new in v2.1:
2+
* Various bug fixes
3+
* Documentation has been significantly improved. The public API is now almost
4+
fully documented.
5+
* Added support for MIPS MSA instruction set.
6+
* Added support for PowerPC VSX v2.06 and v2.07 instruction sets.
7+
* Added support for x86 AVX512BW, AVX512DQ and AVX512VL instruction sets.
8+
* Added support for 64-bit little-endian PowerPC.
9+
* Added support for arbitrary width vectors in extract() and insert()
10+
* Added support for arbitrary source vectors to to_int8(), to_uint8(),
11+
to_int16(), to_uint16(), to_int32(), to_uint32(), to_int64(), to_uint64(),
12+
to_float32(), to_float64().
13+
* Added support for per-element integer shifts to shift_r() and shift_l().
14+
Fallback paths are provided for SSE2-AVX instruction sets that lack
15+
hardware per-element integer shift support.
16+
* Make shuffle_bytes16(), shuffle_zbytes16(), permute_bytes16() and
17+
permute_zbytes() more generic.
18+
* New functions: popcnt, reduce_popcnt, for_each, to_mask()
19+
* Xcode is now supported.
20+
* The library has been refactored in such a way that older compilers are able
21+
to optimize vector emulation code paths much better than before.
22+
* Deprecation: implicit conversion operators to native vector types has been
23+
deprecated and a replacement method has been provided instead. The implicit
24+
conversion operators may lead to wrong code being accepted without a
25+
compile error on Clang.
26+

What's new in v2.0:

329
* Various bug fixes.
30+
* Intel compiler is now supported on Windows. Newer versions of other compilers
31+
are now supported.
