21This directory contains all code for the mpn layer of GMP.
22
23Most subdirectories contain machine-dependent code, written in assembly or C.
24The `generic' subdirectory contains default code, used when there is no
25machine-dependent replacement for a particular machine.
26
27There is one subdirectory for each ISA family. Note that e.g., 32-bit SPARC
28and 64-bit SPARC are very different ISA's, and thus cannot share any code.
29
30A particular compile will only use code from one subdirectory, and the
31`generic' subdirectory. The ISA-specific subdirectories contain hierachies of
32directories for various architecture variants and implementations; the
33top-most level contains code that runs correctly on all variants.
