[Tinycc-devel] libtcc not working properly on x86-64 targets

[Michael Kuklinski]

When I attempt to use libtcc on 64-bit targets, and I push a symbol to a function defined in my program, It seems as though only 32-bits of the address of the function are being used.

 

void print (const char *str)

{

      printf(str);

}

 

int main ()

{

      TCCState *compile_state = tcc_new();

      const char * program =

            "                                                     \

            int main()                                      \

            {                                                     \

                  print(\"hello, world\");            \

                  return 0;                                 \

            }                                                     \

            ";

      int error = tcc_compile_string(compile_state, program);

      void *test = (void*)print;

      int r = tcc_add_symbol(compile_state, "print", (void*)print);

      tcc_set_output_type(compile_state, TCC_OUTPUT_MEMORY);

      tcc_run(compile_state, 0, 0);

      return 0;

}

 

Such works on 32-bit targets, but not 64, as it chops off all bits past 32.

 

I have tried this on both the master version release as well as the latest release on your CVS. Not sure where the chopping is occuring as the code is somewhat of a mess.
