Re: [PATCH] Fix PR17687 sincos -> cexp canonicalization (2nd try)



even a pass doing proper
gimplification on a folded tree will hit the ICE as we have in build2

  if (code == MODIFY_EXPR && cfun && cfun->gimplified)
    {
      /* We should be talking GIMPLE_MODIFY_STMT by now.  */
      gcc_unreachable ();
    }

which is IMHO broken. This is more for verify_stmts.

Agreed; or for tsi_link_{before,after}.
