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