/* SIMDe targets a very wide range of standards and compilers, and our
 * goal is to compile cleanly even with extremely aggressive warnings
 * (i.e., -Weverything in clang, -Wextra in GCC, /W4 for MSVC, etc.)
 * treated as errors.
 *
 * While our preference is to resolve the underlying issue a given
 * diagnostic is warning us about, sometimes that's not possible.
 * Fixing a warning in one compiler may cause problems in another.
 * Sometimes a warning doesn't really apply to us (false positives),
 * and sometimes adhering to a warning would mean dropping a feature
 * we *know* the compiler supports since we have tested specifically
 * for the compiler or feature.
 *
 * When practical, warnings are only disabled for specific code.  For
 * a list of warnings which are enabled by default in all SIMDe code,
 * see SIMDE_DISABLE_UNWANTED_DIAGNOSTICS.  Note that we restore the
 * warning stack when SIMDe is done parsing, so code which includes
 * SIMDe is not deprived of these warnings.
