1 This directory contains all code for the mpn layer of GMP.
3 Most subdirectories contain machine-dependent code, written in assembly or C.
4 The `generic' subdirectory contains default code, used when there is no
5 machine-dependent replacement for a particular machine.
7 There is one subdirectory for each ISA family. Note that e.g., 32-bit SPARC
8 and 64-bit SPARC are very different ISA's, and thus cannot share any code.
10 A particular compile will only use code from one subdirectory, and the
11 `generic' subdirectory. The ISA-specific subdirectories contain hierachies of
12 directories for various architecture variants and implementations; the
13 top-most level contains code that runs correctly on all variants.
