From d08da154967820a36c8f11049e3953db9ef8c59f Mon Sep 17 00:00:00 2001 From: wlott <wlott> Date: Fri, 16 Nov 1990 04:35:34 +0000 Subject: [PATCH] Added lisp sigint handler so Scott doesn't have to deal with LDB. If you want LDB, just run lisp with the ``-monitor'' switch. --- code/signal.lisp | 14 +++++++++----- 1 file changed, 9 insertions(+), 5 deletions(-) diff --git a/code/signal.lisp b/code/signal.lisp index fb55c1c3d..ef6900176 100644 --- a/code/signal.lisp +++ b/code/signal.lisp @@ -7,7 +7,7 @@ ;;; Scott Fahlman (FAHLMAN@CMUC). ;;; ********************************************************************** ;;; -;;; $Header: /Volumes/share2/src/cmucl/cvs2git/cvsroot/src/code/signal.lisp,v 1.7 1990/10/14 19:08:58 ram Exp $ +;;; $Header: /Volumes/share2/src/cmucl/cvs2git/cvsroot/src/code/signal.lisp,v 1.8 1990/11/16 04:35:34 wlott Exp $ ;;; ;;; Code for handling UNIX signals. ;;; @@ -27,6 +27,8 @@ (defconstant sig_dfl 0) (defconstant sig_ign 1) +(proclaim '(special lisp::lisp-command-line-list)) + ;;;; Utilities for dealing with signal names and numbers. @@ -222,9 +224,10 @@ scp) mach:sigcontext t)) - (,function ,(concatenate 'simple-string what " at #x~x.") - (sap-int - (alien-access (mach:sigcontext-pc (alien-value sc)))))))) + (system:without-hemlock + (,function ,(concatenate 'simple-string what " at #x~x.") + (sap-int + (alien-access (mach:sigcontext-pc (alien-value sc))))))))) (define-signal-handler sigint-handler "Interrupted" break) (define-signal-handler sigill-handler "Illegal Instruction") @@ -242,7 +245,8 @@ (defun signal-init () "Enable all the default signals that Lisp knows how to deal with." - #+nil (enable-interrupt :sigint #'sigint-handler) + (unless (member "-monitor" lisp::lisp-command-line-list :test #'string=) + (enable-interrupt :sigint #'sigint-handler)) (enable-interrupt :sigquit #'sigquit-handler) (enable-interrupt :sigill #'sigill-handler) (enable-interrupt :sigtrap #'kernel::internal-error) -- GitLab
