-;;; Commentary:
-
-;; Produce in find-gc-unsafe-list the set of all functions that may invoke GC.
-;; This expects the Emacs sources to live in find-gc-source-directory.
-
-;;; Code:
-
-(defvar find-gc-unsafe-list nil
-  "The list of unsafe functions is placed here by `find-gc-unsafe'.")
-
-(defvar find-gc-source-directory
-  (file-name-as-directory (expand-file-name "src" source-directory))
-  "Directory containing Emacs C sources.")
-
-(defvar find-gc-subrs-callers nil
-  "Alist of users of subrs, from GC testing.
-Each entry has the form (FUNCTION . FUNCTIONS-THAT-CALL-IT).")
-
-(defvar find-gc-subrs-called nil
-  "Alist of subrs called, in GC testing.
-Each entry has the form (FUNCTION . FUNCTIONS-IT-CALLS).")
-
-
-;;; Functions on this list are safe, even if they appear to be able
-;;; to call the target.
-
-(defvar find-gc-noreturn-list '(Fsignal Fthrow wrong_type_argument))
-
-;;; This was originally generated directory-files, but there were
-;;; too many files there that were not actually compiled.  The
-;;; list below was created for a HP-UX 7.0 system.
