            Bug ID: 107018
           Summary: [13 Regression] libgcc unwind-dw2-fde references
                    undeclared variable
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dje at gcc dot gnu.org
  Target Milestone: ---

in_shutdown is declared within #ifdef ATOMIC_FDE_FAST_PATH but used outside the
scope of that macro.  This causes an undeclared variable that causes libgcc
build to fail and breaks bootstrap.



#ifdef ATOMIC_FDE_FAST_PATH
#include "unwind-dw2-btree.h"

static struct btree registered_frames;
static bool in_shutdown;

static void
release_registered_frames (void) __attribute__ ((destructor (110)));
static void
release_registered_frames (void)
{
  /* Release the b-tree and all frames. Frame releases that happen later are
   * silently ignored */
  btree_destroy (&registered_frames);
  in_shutdown = true;
}

static void
get_pc_range (const struct object *ob, uintptr_type *range);
static void
init_object (struct object *ob);
