This is a new implementation of ffiasm. If you need access to the original (and now obsoleted) implemenation at https://github.com/iden3/ffiasm-old .
This package is a script that generates a Finite field Library in Intel64 / ARM64 Assembly
install g++ nasm ang gmp library if you don't have it.
npm install -g ffiasm
mkdir myProject
cd myProject
buildzqfield -q 21888242871839275222246405745257275088548364400416034343698204186575808495617 -n Fr
You now will have two files fr.cpp, fr.hpp and fr.asm
ls
If you are in linux:
nasm -felf64 fr.asm
If you are in a mac:
nasm -fmacho64 --prefix _ fr.asm
Create a file named main.cpp to use the library
#include <stdio.h>
#include <stdlib.h>
#include "fr.hpp"
int main() {
Fr_init();
FrElement a;
a.type = Fr_SHORT;
a.shortVal = 2;
FrElement b;
b.type = Fr_SHORT;
b.shortVal = 6;
FrElement c;
Fr_mul(&c, &a, &b);
char *c1 = Fr_element2str(&c);
printf("Result: %s\n", c1);
free(c1);
}Compile it
g++ main.cpp fr.o fr.cpp -o example -lgmp
Run it
./example
npm run benchmark
