I cross-compiled compiler-rt project from x86_64-Windows to AArch64-Linux and then tested on QEmu-AArch64-Linux . I thought that the built-in doesn't need any header file inclusion. Apparently for different host platforms the built-in behaves differently, perhaps that's due to compiler version. I'll look into this.
