Function validate_cpu_isa

Source/astcenccli_entry.cpp:222–257

* @brief Validate CPU ISA support meets the requirements of this build of the library. * * Each library build is statically compiled for a particular set of CPU ISA features, such as the * SIMD support or other ISA extensions such as POPCNT. This function checks that the host CPU * actually supports everything this build needs. * * @return Return @c true if validated, @c false otherwise. */

 * @return Return @c true if validated, @c false otherwise.
