froofyJIT Description

froofyJIT is a C++ 'syntactic sugar' front-end for Paolo Bonzini's GNU lightning library for dynamic native code generation. froofyJIT is a C++ 'syntactic sugar' front-end for Paolo Bonzini's GNU lightning library for dynamic native code generation. froofyJIT program uses C++'s powerful language facilities to allow GNU lightning instructions to be expressed in a more concise way that approximates a 'real' assembly language.Below is a program which uses froofyJIT to compute a Fibonacci number (directly translated from tests/fib.c in GNU lightning):#include < cstdlib >#include < iostream >#include "froofy/jit.h"static jit_insn codeBuffer;typedef int (*pifi)(int);int main(){ pifi nfibs; int in; { using namespace froofy::jit; label< > basis; nfibs/ !org, codeBuffer; prolog, 1; !arg< ui > in; getarg< ui > v0, in; blti< ui > basis, v0, 2; subi< ui > v1, v0, 1; subi< ui > v2, v0, 2; prepare< i > 1; pusharg< ui > v1; finish, nfibs; retval< i > v1; prepare< i > 1; pusharg< ui > v2; finish, nfibs; retval< i > v2; addi< ui > v1, v1, 1; addr< ui > rr, v1, v2; ret --; basis/ movi< i > rr, 1; ret --; !end, codeBuffer; } std::cout
