--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Yes
```
__asm__(
".text  \n"
".def my_add; .scl 3; .type 32; .endef  \n"
//".globl my_add  \n" ////////////////////////
"my_add:  \n"
"  lea eax, [rcx + rdx]  \n"
"  ret  \n"
::":"(my_add)
);
```
But that is currently not implemented with LTO.
