- str(e) did work in previous pytest version
- but the correct usage is str(e.value)
- in newer pytest version the string for the e object is changed so
  the tests did not work any more

- numpy constants get directly their numpy type
- integer functions check for integer types at construction

- for example: sqrt(cast_func(3, double)) previously printed "sqrt(3)"
  instead of "sqrt(3.0)" leading to errors in CUDA code

Add KernelFunction.fields_written

AES-NI Random Number Generator

Fix error message of CBackend for unsupported nodes

See merge request pycodegen/pystencils!27

Bugfix: Readd __launch_bounds__ for dialect 'cuda'

See merge request pycodegen/pystencils!32

Bugfix: TypedSymbol.is_negative should not be implemented in terms of super().is_positive

See merge request pycodegen/pystencils!31

super().is_positive

This can lead to surprising simplifications

Philox tests and clean up

- allow AST nodes in assignment collection to e.g. put RNG nodes in
  LB method

Remove deprecation warning ('cachedir' parameter has been deprecated)

See merge request !24

Warning was:

```
  /localhome/seitz_local/projects/pystencils/pystencils/cache.py:15: DeprecationWarning: The 'cachedir' parameter has been deprecated in
version 0.12 and will be removed in version 0.14.
  You provided "cachedir='/localhome/seitz_local/.cache/pystencils'", use "location='/localhome/seitz_local/.cache/pystencils'" instead.
    disk_cache = Memory(cachedir=cache_dir, verbose=False).cache
```

Make generate_c also work if astnode does not have member `instruction_set`

See merge request !25

Add RELEASE-VERSION to .gitignore

implemented derivation of gradient weights via rotation

See merge request !15

Markus Holzer authored 5 years ago and Markus Holzer committed 5 years ago

derive gradient weights of other direction with
already calculated weights of one direction
via rotation and apply them to a field.

as_matrix gives now a deprecated warning and as_array is no newly implemented to replace it. as_array works with MutableDenseNDimArray now instead of Matrix

`instruction_set`

Declare FieldShapeSymbol and FieldStrideSymbol as strictly positive

Fix #10: Avoid jinja2 dependency

Closes #10

See merge request !18

This commit avoid dependency of core pystencils on jinja2.
However this could make the printing of some AST-nodes less elegant.

Remove floor, ceiling for integer symbols
