From 655ab5c187d97b16e6f82790616dfe9a01c30b04 Mon Sep 17 00:00:00 2001 From: wlott <wlott> Date: Tue, 28 Apr 1992 15:38:37 +0000 Subject: [PATCH] Changed number-stack-displacement to only take into account the space needed for the register window. The call-out vop now takes the callee save area into account when allocating the frame. --- compiler/sparc/call.lisp | 11 ++++------- 1 file changed, 4 insertions(+), 7 deletions(-) diff --git a/compiler/sparc/call.lisp b/compiler/sparc/call.lisp index eb47ee8f1..3f4a09922 100644 --- a/compiler/sparc/call.lisp +++ b/compiler/sparc/call.lisp @@ -7,7 +7,7 @@ ;;; Scott Fahlman or slisp-group@cs.cmu.edu. ;;; (ext:file-comment - "$Header: /Volumes/share2/src/cmucl/cvs2git/cvsroot/src/compiler/sparc/call.lisp,v 1.11 1992/04/27 20:03:45 wlott Exp $") + "$Header: /Volumes/share2/src/cmucl/cvs2git/cvsroot/src/compiler/sparc/call.lisp,v 1.12 1992/04/28 15:38:37 wlott Exp $") ;;; ;;; ********************************************************************** ;;; @@ -145,14 +145,11 @@ ;;; NUMBER-STACK-DISPLACEMENT ;;; -;;; The number of bytes reserved above the number stack pointer. +;;; The number of bytes reserved above the number stack pointer.
