对于带有BMI2指令的 CPU，可以使用内置函数在 GCC 中使用并行位存储 (pdep) 和并行位提取 (pext) ：
unsigned int _pdep_u32 (unsigned int, unsigned int)unsigned int _pext_u32 (unsigned int, unsigned int)unsigned long long _pdep_u64 (unsigned long long, unsigned long long)unsigned long long _pext_u64 (unsigned long long, unsigned long long)
它们在英特尔编译器上的等价物是什么？铿锵声？
