Patch ping

[Jakub Jelinek]

Hi!

I'd like to ping two patches:

PR c++/79572
  - ubsan instrumentation of reference binding to NULL if the reference
    is folded into INTEGER_CST with REFERENCE_TYPE
    http://gcc.gnu.org/ml/gcc-patches/2017-03/msg01255.html

PR debug/79255
  - dwarf2out profiledbootstrap ICE while building gnat;
    either the posted patch
    http://gcc.gnu.org/ml/gcc-patches/2017-03/msg01257.html
    or in gen_decl_die:
   case FUNCTION_DECL:
+    /* decl is NULL only if when processing a function declaration in
+       BLOCK_NONLOCALIZED_VARS.  It is a normal declaration, not an
+       abstract copy of something, so make sure we don't handle it
+       like function inlined into something.  */
+    if (decl == NULL_TREE)
+      {
+       decl = origin;
+       origin = NULL_TREE;
+      }
    or something else (another possibility is to replace all decl
    uses in case FUNCTION_DECL with decl_or_origin and
-         if (!origin)
-           origin = decl_class_context (decl);
+         if (!decl || !origin)
+           origin = decl_class_context (decl_or_origin);
    )?
