From 721357b86856505324b5f32584d5eae0ba9ab4ac Mon Sep 17 00:00:00 2001 From: Mattias Engdegård Date: Sun, 2 Jan 2022 11:35:16 +0100 Subject: Remove the unused unbind-all bytecode It was implemented but never generated, originally intended for TCO in the pre-lexbind era (which was semantically dubious anyway). Removing it speeds up the interpreter because there is no longer any need for the outermost `count` variable unless checking is enabled. * lisp/emacs-lisp/bytecomp.el: * lisp/emacs-lisp/comp.el (comp-limplify-lap-inst): * src/bytecode.c (BYTE_CODES, exec_byte_code): Remove definition and implementation of unbind-all, freeing up the opcode for other purposes. --- lisp/emacs-lisp/comp.el | 1 - 1 file changed, 1 deletion(-) (limited to 'lisp/emacs-lisp/comp.el') diff --git a/lisp/emacs-lisp/comp.el b/lisp/emacs-lisp/comp.el index 74b0b1197be..3c61063a3cb 100644 --- a/lisp/emacs-lisp/comp.el +++ b/lisp/emacs-lisp/comp.el @@ -1943,7 +1943,6 @@ and the annotation emission."
