Note that e.g., 32-bit SPARC +and 64-bit SPARC are very different ISA's, and thus cannot share any code. + +A particular compile will only use code from one subdirectory, and the +`generic' subdirectory. The ISA-specific subdirectories contain hierachies of +directories for various architecture variants and implementations; the +top-most level contains code that runs correctly on all variants. |
