Those applications can include a copy of +mini-gmp to get a GMP-compatible interface with small footprint. One +can also arrange for optional linking with the real GMP library, using +mini-gmp as a fallback when for some reason GMP is not available, or +not desired as a dependency. + +The supported GMP subset of the mpn and mpz interfaces is declared in +mini-gmp.h, and implemented in mini-gmp.c. The implemented +functions are fully compatible with the corresponding GMP functions, +as specified in the GMP manual, with a few exceptions: + + mpz_export and mpz_import support only NAILS = 0. + +The performance target for mini-gmp is to be at most 10 times slower +than the real GMP library, for numbers of size up to a few hundred +bits. No asymptotically fast algorithms are included in mini-gmp, so +it will be many orders of magnitude slower than GMP for very large +numbers. + +The supported GMP subset of the mpq layer is declared in mini-mpq.h, +and implemented in mini-mpq.c. + +You should never "install" mini-gmp. Applications can either just +#include mini-gmp.c (but then, beware that it defines several macros +and functions outside of the advertised interface), and if needed +#include mini-mpq.c in a later line (order is important). Or compile +mini-gmp.c and mini-mpq.c as separate compilation units, and use the +declarations in mini-gmp.h and mini-mpq.h. + +The tests subdirectory contains a testsuite. To use it, you need GMP +and GNU make. Just run make check in the tests directory. If the +hard-coded compiler settings are not right, you have to either edit the +Makefile or pass overriding values on the make command line (e.g., +make CC=cc check). + +The initial version of mini-gmp was put together by Niels Möller +, with a fair amount of copy-and-paste from the +GMP sources. -- cgit v1.2.3
