            Bug ID: 61553
           Summary: __atomic_store with non-pointer arg ICE
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: bstarynk at gcc dot gnu.org

Created attachment 32968
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=32968&action=edit
faulty source code

(On Debian/Sid/AMD64)

The attached file (with an incorrect __atomic_store) gives an ICE.

badatomicstore.c: In function ‘clear_s1’:
badatomicstore.c:9:6: internal compiler error: in tree_to_uhwi, at tree.h:3660
      __atomic_store(s->i_name, NULL, __ATOMIC_SEQ_CST);
      ^
Please submit a full bug report,


Of course, the instruction is incorrect; it should be

     __atomic_store_n(&s->i_name, NULL, __ATOMIC_SEQ_CST);

Hi Avi, I am sorry nobody looked into this earlier.

David indicated this actually is covered in
https://gcc.gnu.org/onlinedocs/gcc/Extended-Asm.html#i386Operandmodifiers

Can you please advise if there is anything you see missing or there
are changes you'd still like to see?
