+Most subdirectories contain machine-dependent code, written in assembly or C.
+The `generic' subdirectory contains default code, used when there is no
machine-dependent replacement for a particular machine.
-There is one subdirectory for each architecture. Note that e.g., 32-bit
-sparc and 64-bit sparc cannot share any code, and are therefore considered
-completely different architecture.
+There is one subdirectory for each ISA family. Note that e.g., 32-bit SPARC
