+  * For any-amd64 and any-i386: compile multiple times with reducing levels of

+ *
+ * Different compilers define different preprocessor macros for the
+ * same architecture.  This is an attempt to provide a single
+ * interface which is usable on any compiler.
+ *
+ * In general, a macro named SIMDE_ARCH_* is defined for each
+ * architecture the CPU supports.  When there are multiple possible
+ * versions, we try to define the macro to the target version.  For
+ * example, if you want to check for i586+, you could do something
+ * like:
+ *
+ *   #if defined(SIMDE_ARCH_X86) && (SIMDE_ARCH_X86 >= 5)
+ *   ...
+ *   #endif
+ *
+ * You could also just check that SIMDE_ARCH_X86 >= 5 without checking
+ * if it's defined first, but some compilers may emit a warning about
+ * an undefined macro being used (e.g., GCC with -Wundef).
+ *
+ * This was originally created for SIMDe
+ * <https://github.com/nemequ/simde> (hence the prefix), but this
+ * header has no dependencies and may be used anywhere.  It is
+ * originally based on information from
+ * <https://sourceforge.net/p/predef/wiki/Architectures/>, though it
+ * has been enhanced with additional information.
+ *
+ * If you improve this file, or find a bug, please file the issue at
+ * <https://github.com/nemequ/simde/issues>.  If you copy this into
+ * your project, even if you change the prefix, please keep the links
+ * to SIMDe intact so others know where to report issues, submit
+ * enhancements, and find the latest version. */

+   operations using more simple vector operations instead of minimize
+   serial work.
+
+   As an example, consider the _mm_add_ss(a, b) function from SSE,
+   which returns { a0 + b0, a1, a2, a3 }.  This pattern is repeated
+   for other operations (sub, mul, etc.).
+
+   The naïve implementation would result in loading a0 and b0, adding
+   them into a temporary variable, then splicing that value into a new
+   vector with the remaining elements from a.
+
+   On platforms which support vectorization, it's generally faster to
+   simply perform the operation on the entire vector to avoid having
+   to move data between SIMD registers and non-SIMD registers.
+   Basically, instead of the temporary variable being (a0 + b0) it
+   would be a vector of (a + b), which is then combined with a to form
+   the result.
+
+   By default, SIMDe will prefer the pure-vector versions if we detect
+   a vector ISA extension, but this can be overridden by defining
