1 ;;;; This file is for compiler tests which have side effects (e.g.
2 ;;;; executing DEFUN) but which don't need any special side-effecting
3 ;;;; environmental stuff (e.g. DECLAIM of particular optimization
4 ;;;; settings). Similar tests which *do* expect special settings may
5 ;;;; be in files compiler-1.impure.lisp, compiler-2.impure.lisp, etc.
7 ;;;; This software is part of the SBCL system. See the README file for
8 ;;;; more information.
9 ;;;;
10 ;;;; While most of SBCL is derived from the CMU CL system, the test
11 ;;;; files (like this one) were written from scratch after the fork
12 ;;;; from CMU CL.
13 ;;;;
14 ;;;; This software is in the public domain and is provided with
15 ;;;; absolutely no warranty. See the COPYING and CREDITS files for
16 ;;;; more information.
