tests/compiler.impure.lisp

   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.
