内联汇编对“ asm”的不可能限制

Question

我在2.50GHz @IntelXeon®Platinum 8180 CPU上使用的是g ++版本8.1.1和Fedora版本18

./src/trackers/biptr.hpp: In member function ‘bool FatPtr<T>::WideCAS(fat_pointer_rec<T>&, fat_pointer_rec<T>&, std::memory_order) [with T = SortedUnorderedMapRange<std::__cxx11::basic_string<char>, std::__cxx11::basic_string<char> >::Node]’:
./src/trackers/biptr.hpp:55:87: error: impossible constraint in ‘asm’
   :"a" (old_value.ptr), "d" (old_value.tag), "b" (new_value.ptr), "c" (new_value.tag));
                                                                                       ^

make: *** [Makefile:337: default] Error 2

我遇到以下错误。

var importedData: [your-structure] = []

有什么解决方法吗？
