2. Dynamic Code Generation

int add(int a, int b) { return a + b; } char my_program[] = "int foo(int n)\n" "{\n" " printf(\"Hello World!\\n\");\n" " printf(\"fib(%d) = %d\\n\", n, fib(n));\n" " printf(\"add(%d, %d) = %d\\n\", n, 2 * n, add(n, 2 * n));\n" " return 0;\n" "}\n";

Code Generation

TCCState *s; s = tcc_new(); tcc_set_output_type(s, TCC_OUTPUT_MEMORY); if (tcc_compile_string(s, my_program) == -1) return 1; tcc_add_symbol(s, "add", add); size = tcc_relocate(s, NULL); if (size == -1) return 1; mem = malloc(size); tcc_relocate(s, mem); func = tcc_get_symbol(s, "foo"); if (!func) return 1; tcc_delete(s); func(32); free(mem);
