--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
But a toplevel asm isn't a "statement" in the sense of parsing.  Still
confirmed.  Note that I'm not sure we can handle no-reorder for toplevel
asms, IIRC they are not entities in the symtab.  I don't remember off head
where they are recorded either ...

Btw, I don't get

t.c:3:1: warning: attributes at the beginning of statement are ignored
[-Wattributes]
    3 | [[gnu::no_reorder]]
      | ^~~~~~~~~~~~~~~~~~~

unless I wrap your source inside a function.  Was your testcase complete?
