#include <iostream>
extern "C" {
__attribute__((constructor(101), used, retain, section(".llvm.keep,.init.250"), noinline, visibility("hidden"))) static void
_init_cpu_features() {
__builtin_cpu_init();
std::cout << "?" << std::endl;
};
}
build this function to a static lib _initd.lib, link it by cmake: "set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -L${CMAKE_CURRENT_LIST_DIR}/libs -l_initd.lib ")"
howevery, "?" not printed, and __builtin_cpu_supports always return false in main.cpp
