"""This test suite tests various expressions that are used as dimension
specifications.
There exists two usage cases where analyzing dimensions
specifications are important.
In the first case, the size of output arrays must be defined based
on the inputs to a Fortran function. Because Fortran supports
arbitrary bases for indexing, for instance, `arr(lower:upper)`,
f2py has to evaluate an expression `upper - lower + 1` where
`lower` and `upper` are arbitrary expressions of input parameters.
The evaluation is performed in C, so f2py has to translate Fortran
expressions to valid C expressions (an alternative approach is
that a developer specifies the corresponding C expressions in a
.pyf file).
In the second case, when user provides an input array with a given
size but some hidden parameters used in dimensions specifications
need to be determined based on the input array size. This is a
harder problem because f2py has to solve the inverse problem: find
a parameter `p` such that `upper(p) - lower(p) + 1` equals to the
size of input array. In the case when this equation cannot be
solved (e.g. because the input array size is wrong), raise an
error before calling the Fortran function (that otherwise would
likely crash Python process when the size of input arrays is
wrong). f2py currently supports this case only when the equation
is linear with respect to unknown parameter.

# the OS loader; they are necessary when linking against a DLL not in the
# system path; in particular, official python 2.6 binary is built against the
# MS runtime 9 (the one from VS 2008), which is not available on most windows
# systems; python 2.6 installer does install it in the Win SxS (Side by side)
# directory, but this requires the manifest for this to work. This is a big
# mess, thanks MS for a wonderful system.

exec_command
Implements exec_command function that is (almost) equivalent to
commands.getstatusoutput function but on NT, DOS systems the
returned status is actually correct (though, the returned status
values may be different by a factor). In addition, exec_command
takes keyword arguments for (re-)defining environment variables.
Provides functions:
exec_command --- execute command in a specified directory and
in the modified environment.
find_executable --- locate a command using info from environment
variable PATH. Equivalent to posix `which`
command.

"""
This file defines a set of system_info classes for getting
information about various resources (libraries, library directories,
include directories, etc.) in the system. Usage:
info_dict = get_info(<name>)
where <name> is a string 'atlas','x11','fftw','lapack','blas',
'lapack_src', 'blas_src', etc. For a complete list of allowed names,
see the definition of get_info() function below.
Returned info_dict is a dictionary which is compatible with
distutils.setup keyword arguments. If info_dict == {}, then the
asked resource is not available (system_info could not find it).
Several *_info classes specify an environment variable to specify
the locations of software. When setting the corresponding environment
variable to 'None' then the software will be ignored, even when it
is available in system.
Global parameters:
system_info.search_static_first - search static libraries (.a)
in precedence to shared ones (.so, .sl) if enabled.
system_info.verbosity - output the results to stdout if enabled.
The file 'site.cfg' is looked for in
1) Directory of main setup.py file being run.
2) Home directory of user running the setup.py file as ~/.numpy-site.cfg
3) System wide directory (location of this file...)
The first one found is used to get system configuration options The
format is that used by ConfigParser (i.e., Windows .INI style). The
section ALL is not intended for general use.
Appropriate defaults are used if nothing is specified.
The order of finding the locations of resources is the following:
1. environment variable
2. section in site.cfg
3. DEFAULT section in site.cfg
4. System default search paths (see ``default_*`` variables below).
Only the first complete match is returned.
Currently, the following classes are available, along with their section names:

Note that blas_opt_info and lapack_opt_info honor the NPY_BLAS_ORDER
and NPY_LAPACK_ORDER environment variables to determine the order in which
specific BLAS and LAPACK libraries are searched for.
This search (or autodetection) can be bypassed by defining the environment
variables NPY_BLAS_LIBS and NPY_LAPACK_LIBS, which should then contain the
exact linker flags to use (language will be set to F77). Building against
Netlib BLAS/LAPACK or stub files, in order to be able to switch BLAS and LAPACK
implementations at runtime. If using this to build NumPy itself, it is
recommended to also define NPY_CBLAS_LIBS (assuming your BLAS library has a
CBLAS interface) to enable CBLAS usage for matrix multiplication (unoptimized
otherwise).
Example:
----------
[DEFAULT]
# default section
library_dirs = /usr/lib:/usr/local/lib:/opt/lib
include_dirs = /usr/include:/usr/local/include:/opt/include
src_dirs = /usr/local/src:/opt/src
# search static libraries (.a) in preference to shared ones (.so)
search_static_first = 0
[fftw]
libraries = rfftw, fftw
[atlas]
library_dirs = /usr/lib/3dnow:/usr/lib/3dnow/atlas
# for overriding the names of the atlas libraries
libraries = lapack, f77blas, cblas, atlas
[x11]
library_dirs = /usr/X11R6/lib
include_dirs = /usr/X11R6/include
----------
Note that the ``libraries`` key is the default setting for libraries.

Notes
-----
The form of each element of the files sequence is very flexible
allowing many combinations of where to get the files from the package
and where they should ultimately be installed on the system. The most
basic usage is for an element of the files argument sequence to be a
simple filename. This will cause that file from the local path to be
installed to the installation path of the self.name package (package
path). The file argument can also be a relative path in which case the
entire relative path will be installed into the package directory.
Finally, the file can be an absolute path name in which case the file
will be found at the absolute path name but installed to the package
path.
This basic behavior can be augmented by passing a 2-tuple in as the
file argument. The first element of the tuple should specify the
relative path (under the package install directory) where the
remaining sequence of files should be installed to (it has nothing to
do with the file-names in the source distribution). The second element
of the tuple is the sequence of files that should be installed. The
files in this sequence can be filenames, relative paths, or absolute
paths. For absolute paths the file will be installed in the top-level
package installation directory (regardless of the first argument).
Filenames and relative path names will be installed in the package
install directory under the path name given as the first element of
the tuple.
Rules for installation paths:
#. file.txt -> (., file.txt)-> parent/file.txt
#. foo/file.txt -> (foo, foo/file.txt) -> parent/foo/file.txt
#. /foo/bar/file.txt -> (., /foo/bar/file.txt) -> parent/file.txt
#. ``*``.txt -> parent/a.txt, parent/b.txt
#. foo/``*``.txt`` -> parent/foo/a.txt, parent/foo/b.txt
#. ``*/*.txt`` -> (``*``, ``*``/``*``.txt) -> parent/c/a.txt, parent/d/b.txt
#. (sun, file.txt) -> parent/sun/file.txt
#. (sun, bar/file.txt) -> parent/sun/file.txt
#. (sun, /foo/bar/file.txt) -> parent/sun/file.txt
#. (sun, ``*``.txt) -> parent/sun/a.txt, parent/sun/b.txt
#. (sun, bar/``*``.txt) -> parent/sun/a.txt, parent/sun/b.txt
#. (sun/``*``, ``*``/``*``.txt) -> parent/sun/c/a.txt, parent/d/b.txt
An additional feature is that the path to a data-file can actually be
a function that takes no arguments and returns the actual path(s) to
the data-files. This is useful when the data files are generated while
building the package.
Examples
--------
Add files to the list of data_files to be included with the package.
>>> self.add_data_files('foo.dat',
... ('fun', ['gun.dat', 'nun/pun.dat', '/tmp/sun.dat']),
... 'bar/cat.dat',

Parameters
----------
template : str
The path of the template, relatively to the current package path.
install_dir : str
Where to install the npy-pkg config file, relatively to the current
package path.
subst_dict : dict, optional
If given, any string of the form ``@key@`` will be replaced by
``subst_dict[key]`` in the template file when installed. The install
prefix is always available through the variable ``@prefix@``, since the
install prefix is not easy to get reliably from setup.py.
See also
--------
add_installed_library, get_info
Notes
-----
This works for both standard installs and in-place builds, i.e. the
``@prefix@`` refer to the source directory for in-place builds.
Examples
--------
::
config.add_npy_pkg_config('foo.ini.in', 'lib', {'foo': bar})
Assuming the foo.ini.in file has the following content::
[meta]
Name=@foo@
Version=1.0
Description=dummy description
[default]
Cflags=-I@prefix@/include
Libs=
The generated file will have the following content::
[meta]
Name=bar
Version=1.0
Description=dummy description
[default]
Cflags=-Iprefix_dir/include
Libs=
and will be installed as foo.ini in the 'lib' subpath.
When cross-compiling with numpy distutils, it might be necessary to
use modified npy-pkg-config files. Using the default/generated files
will link with the host libraries (i.e. libnpymath.a). For
cross-compilation you of-course need to link with target libraries,
while using the host Python installation.
You can copy out the numpy/core/lib/npy-pkg-config directory, add a
pkgdir value to the .ini files and set NPY_PKG_CONFIG_PATH environment
variable to point to the directory with the modified npy-pkg-config
files.
Example npymath.ini modified for cross-compilation::
[meta]
Name=npymath
Description=Portable, core math library implementing C99 standard
Version=0.1
[variables]
pkgname=numpy.core
pkgdir=/build/arm-linux-gnueabi/sysroot/usr/lib/python3.7/site-packages/numpy/core

* ``include_dirs``: directories containing library header files
* ``src_dirs``: directories containing library source files

* ``baseline``: minimum CPU features required
* ``found``: dispatched features supported in the system
* ``not found``: dispatched features that are not supported

2. NumPy BLAS/LAPACK Installation Notes
Installing a numpy wheel (``pip install numpy`` or force it
via ``pip install numpy --only-binary :numpy: numpy``) includes
an OpenBLAS implementation of the BLAS and LAPACK linear algebra
APIs. In this case, ``library_dirs`` reports the original build
time configuration as compiled with gcc/gfortran; at run time
the OpenBLAS library is in
``site-packages/numpy.libs/`` (linux), or
``site-packages/numpy/.dylibs/`` (macOS), or
``site-packages/numpy/.libs/`` (windows).
Installing numpy from source
(``pip install numpy --no-binary numpy``) searches for BLAS and
LAPACK dynamic link libraries at build time as influenced by
environment variables NPY_BLAS_LIBS, NPY_CBLAS_LIBS, and
NPY_LAPACK_LIBS; or NPY_BLAS_ORDER and NPY_LAPACK_ORDER;
or the optional file ``~/.numpy-site.cfg``.
NumPy remembers those locations and expects to load the same
libraries at run-time.
In NumPy 1.21+ on macOS, 'accelerate' (Apple's Accelerate BLAS
library) is in the default build-time search order after
'openblas'.

.i or .c or .h, using the following template rules
/**begin repeat -- on a line by itself marks the start of a repeated code
segment
/**end repeat**/ -- on a line by itself marks it's end
After the /**begin repeat and before the */, all the named templates are placed
these should all have the same number of replacements
Repeat blocks can be nested, with each nested block labeled with its depth,
i.e.
/**begin repeat1
*....
*/
/**end repeat1**/
When using nested loops, you can optionally exclude particular
combinations of the variables using (inside the comment portion of the inner loop):
:exclude: var1=value1, var2=value2, ...
This will exclude the pattern where var1 is value1 and var2 is value2 when
the result is being generated.
In the main body each replace will use one entry from the list of named replacements
Note that all #..# forms in a block must have the same number of
comma-separated entries.
Example:
An input file containing
/**begin repeat
* #a = 1,2,3#
* #b = 1,2,3#
*/
/**begin repeat1
* #c = ted, jim#
*/
@a@, @b@, @c@

'<..>' denotes a template.
All function and subroutine blocks in a source file with names that
contain '<..>' will be replicated according to the rules in '<..>'.
The number of comma-separated words in '<..>' will determine the number of
replicates.
'<..>' may have two different forms, named and short. For example,
named:
<p=d,s,z,c> where anywhere inside a block '<p>' will be replaced with
'd', 's', 'z', and 'c' for each replicate of the block.
<_c> is already defined: <_c=s,d,c,z>
<_t> is already defined: <_t=real,double precision,complex,double complex>
short:
<s,d,c,z>, a short form of the named, useful when no <p> appears inside
a block.
In general, '<..>' contains a comma separated list of arbitrary
expressions. If these expression must contain a comma|leftarrow|rightarrow,
then prepend the comma|leftarrow|rightarrow with a backslash.
If an expression matches '\\<index>' then it will be replaced
by <index>-th expression.

optimization, starting from parsing the command arguments, to managing the
relation between the CPU baseline and dispatch-able features,
also generating the required C headers and ending with compiling
the sources with proper compiler's flags.
`CCompilerOpt` doesn't provide runtime detection for the CPU features,
instead only focuses on the compiler side, but it creates abstract C headers
that can be used later for the final runtime dispatching process."""

class _Config:
"""An abstract class holds all configurable attributes of `CCompilerOpt`,
these class attributes can be used to change the default behavior
of `CCompilerOpt` in order to fit other requirements.
Attributes
----------
conf_nocache : bool
Set True to disable memory and file cache.
Default is False.
conf_noopt : bool
Set True to forces the optimization to be disabled,
in this case `CCompilerOpt` tends to generate all
expected headers in order to 'not' break the build.
Default is False.
conf_cache_factors : list
Add extra factors to the primary caching factors. The caching factors
are utilized to determine if there are changes had happened that
requires to discard the cache and re-updating it. The primary factors
are the arguments of `CCompilerOpt` and `CCompiler`'s properties(type, flags, etc).
Default is list of two items, containing the time of last modification
of `ccompiler_opt` and value of attribute "conf_noopt"
conf_tmp_path : str,
The path of temporary directory. Default is auto-created
temporary directory via ``tempfile.mkdtemp()``.
conf_check_path : str
The path of testing files. Each added CPU feature must have a
**C** source file contains at least one intrinsic or instruction that
related to this feature, so it can be tested against the compiler.
Default is ``./distutils/checks``.
conf_target_groups : dict
Extra tokens that can be reached from dispatch-able sources through
the special mark ``@targets``. Default is an empty dictionary.
**Notes**:
- case-insensitive for tokens and group names
- sign '#' must stick in the begin of group name and only within ``@targets``
**Example**:
.. code-block:: console
$ "@targets #avx_group other_tokens" > group_inside.c
>>> CCompilerOpt.conf_target_groups["avx_group"] = \\
"$werror $maxopt avx2 avx512f avx512_skx"
>>> cco = CCompilerOpt(cc_instance)
>>> cco.try_dispatch(["group_inside.c"])
conf_c_prefix : str
The prefix of public C definitions. Default is ``"NPY_"``.
conf_c_prefix_ : str
The prefix of internal C definitions. Default is ``"NPY__"``.
conf_cc_flags : dict
Nested dictionaries defining several compiler flags
that linked to some major functions, the main key
represent the compiler name and sub-keys represent
flags names. Default is already covers all supported
**C** compilers.
Sub-keys explained as follows:
"native": str or None
used by argument option `native`, to detect the current
machine support via the compiler.
"werror": str or None
utilized to treat warning as errors during testing CPU features
against the compiler and also for target's policy `$werror`
via dispatch-able sources.
"maxopt": str or None
utilized for target's policy '$maxopt' and the value should
contains the maximum acceptable optimization by the compiler.
e.g. in gcc `'-O3'`
**Notes**:
* case-sensitive for compiler names and flags
* use space to separate multiple flags
* any flag will tested against the compiler and it will skipped
if it's not applicable.
conf_min_features : dict
A dictionary defines the used CPU features for
argument option `'min'`, the key represent the CPU architecture
name e.g. `'x86'`. Default values provide the best effort
on wide range of users platforms.
**Note**: case-sensitive for architecture names.
conf_features : dict
Nested dictionaries used for identifying the CPU features.
the primary key is represented as a feature name or group name
that gathers several features. Default values covers all
supported features but without the major options like "flags",
these undefined options handle it by method `conf_features_partial()`.
Default value is covers almost all CPU features for *X86*, *IBM/Power64*
and *ARM 7/8*.
Sub-keys explained as follows:
"implies" : str or list, optional,
List of CPU feature names to be implied by it,
the feature name must be defined within `conf_features`.
Default is None.
"flags": str or list, optional
List of compiler flags. Default is None.
"detect": str or list, optional
List of CPU feature names that required to be detected
in runtime. By default, its the feature name or features
in "group" if its specified.
"implies_detect": bool, optional
If True, all "detect" of implied features will be combined.
Default is True. see `feature_detect()`.
"group": str or list, optional
Same as "implies" but doesn't require the feature name to be
defined within `conf_features`.
"interest": int, required
a key for sorting CPU features
"headers": str or list, optional
intrinsics C header file
"disable": str, optional
force disable feature, the string value should contains the
reason of disabling.
"autovec": bool or None, optional
True or False to declare that CPU feature can be auto-vectorized
by the compiler.
By default(None), treated as True if the feature contains at
least one applicable flag. see `feature_can_autovec()`
"extra_checks": str or list, optional
Extra test case names for the CPU feature that need to be tested
against the compiler.
Each test case must have a C file named ``extra_xxxx.c``, where
``xxxx`` is the case name in lower case, under 'conf_check_path'.
It should contain at least one intrinsic or function related to the test case.
If the compiler able to successfully compile the C file then `CCompilerOpt`
will add a C ``#define`` for it into the main dispatch header, e.g.
``#define {conf_c_prefix}_XXXX`` where ``XXXX`` is the case name in upper case.
**NOTES**:
* space can be used as separator with options that supports "str or list"
* case-sensitive for all values and feature name must be in upper-case.
* if flags aren't applicable, its will skipped rather than disable the
CPU feature
* the CPU feature will disabled if the compiler fail to compile
the test file

Parameters
----------
cpu_baseline : str or None
minimal set of required CPU features or special options.
cpu_dispatch : str or None
dispatched set of additional CPU features or special options.
Special options can be:
- **MIN**: Enables the minimum CPU features that utilized via `_Config.conf_min_features`
- **MAX**: Enables all supported CPU features by the Compiler and platform.
- **NATIVE**: Enables all CPU features that supported by the current machine.
- **NONE**: Enables nothing
- **Operand +/-**: remove or add features, useful with options **MAX**, **MIN** and **NATIVE**.
NOTE: operand + is only added for nominal reason.
NOTES:
- Case-insensitive among all CPU features and special options.
- Comma or space can be used as a separator.
- If the CPU feature is not supported by the user platform or compiler,
it will be skipped rather than raising a fatal error.
- Any specified CPU features to 'cpu_dispatch' will be skipped if its part of CPU baseline features
- 'cpu_baseline' force enables implied features.
Attributes
----------
parse_baseline_names : list
Final CPU baseline's feature names(sorted from low to high)
parse_baseline_flags : list
Compiler flags of baseline features
parse_dispatch_names : list
Final CPU dispatch-able feature names(sorted from low to high)
parse_target_groups : dict
Dictionary containing initialized target groups that configured
