--- Comment #13 from nsz at gcc dot gnu.org ---
there could be a format for reducing porting work between ilp32 and lp64 inline
asm:
asm ("ldr %?0, foo" : "=r"(ptr));
where %?0 behaves like %w0 on ilp32 and %x0 on lp64, which is a bit nicer than
doing preprocessor hacks like
#ifdef __LP64__
#define XW "x"
#else
#define XW "w"
#endif
asm ("ldr %" XW "0, foo" : "=r"(ptr));
