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 FNZchecksZNPY_ZNPY__z -march=nativez-O3z-Werror)�native�opt�werrorz--Werror-implicit-function-declaration -Werrorz-xHostz/QxHostz/O3z/Werrorz/O2z/WX)�gcc�clang�icc�iccw�msvczSSE SSE2z SSE SSE2 SSE3� zVSX VSX2z NEON NEON_FP16 NEON_VFPV4 ASIMD)�x86�x64�ppc64�ppc64le�armhf�aarch64� z xmmintrin.h�SSE2)�interest�headers�implies� �SSEz emmintrin.h)r r r � z pmmintrin.h� �SSE3z tmmintrin.h� �SSSE3z smmintrin.h� �SSE41zpopcntintrin.h� �POPCNT)r r � �SSE42z immintrin.h)r r r �implies_detect� �AVXz x86intrin.h� � � �F16C� � z FMA3 AVX2ZAVX512F_REDUCE)r r r$ � extra_checks� �AVX512F�( �AVX512CDzAVX512ER AVX512PF� AVX512_KNL)r r �group�detectr$ �) z)AVX5124FMAPS AVX5124VNNIW AVX512VPOPCNTDQ� AVX512_KNM�* zAVX512VL AVX512BW AVX512DQ� AVX512_SKXzAVX512BW_MASK AVX512DQ_MASK)r r r3 r4 r$ r- �+ Z AVX512VNNI� AVX512_CLX)r r r3 r4 �, zAVX512IFMA AVX512VBMI� AVX512_CNL�- zAVX512_CLX AVX512_CNLz(AVX512VBMI2 AVX512BITALG AVX512VPOPCNTDQ� AVX512_ICLz altivec.hZVSX_ASM)r r r- �VSX)r r r$ �VSX2z arm_neon.h)r r �NEON� NEON_FP16zNEON_FP16 NEON_VFPV4�ASIMD�ASIMDHP) r r r r r r! r# r& �XOP�FMA4r* �FMA3�AVX2r/ r1 r2 r6 r8 r: r< r> r?

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.

process. The mechanism behind it is to takes each source file that specified in 'sources' and branching it into several files depend on special configuration statements that must be declared in the top of each source which contains targeted CPU features, then it compiles every branched source with the proper compiler flags. Parameters ---------- sources : list Must be a list of dispatch-able sources file paths, and configuration statements must be declared inside each file. src_dir : str Path of parent directory for the generated headers and wrapped sources. If None(default) the files will generated in-place. ccompiler: CCompiler Distutils `CCompiler` instance to be used for compilation. If None (default), the provided instance during the initialization will be used instead. **kwargs : any Arguments to pass on to the `CCompiler.compile()` Returns ------- list : generated object files Raises ------ CompileError Raises by `CCompiler.compile()` on compiling failure. DistutilsError Some errors during checking the sanity of configuration statements.
