51 /* note for anyone trying to port an architecture's support files
52 * from CMU CL to SBCL:
54 * CMU CL had architecture-dependent header files included here to
55 * define memory map data:
56 * #ifdef LISP_FEATURE_X86
57 * #include "x86-validate.h"
59 * and so forth. In SBCL, the memory map data are defined at the Lisp
60 * level (compiler/target/parms.lisp) and stuffed into the sbcl.h file
61 * created by GENESIS, so there's no longer a need for an
62 * architecture-dependent header file of memory map data.
