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. + +A particular machine will only use code from one such subdirectory, and the +`generic' subdirectory. The architecture-specific subdirectory contains a +hierachy of directories for various architecture variants and +implementations; the top-most level contains code that runs correctly on all +variants. |
