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

That's also an interesting idea - one which I did not think of.

If you'd like, I can compile my fixes for you so you can patch them into your 
repository.

Glad you got it working.

Btw here is another idea.  You could actually just declare the
function(s) as dllexport and then add the program itself using
tcc_add_file.  It would then use it's own IAT (import address
table) as jump table.

#include <stdio.h>
#include "libtcc.h"

__declspec(dllexport) void print (const char *msg)
{
     printf("Say %s!\n", msg);
}

int main (int argc, char **argv)
{
     TCCState *s = tcc_new();
     tcc_set_output_type(s, TCC_OUTPUT_MEMORY);
     tcc_add_file(s, "this-prog.exe");

     if (tcc_compile_string(s, "main() { print(\"hello\"); }"))
         fprintf(stderr, "compile error\n");
     else
         tcc_run(s, 0, 0);

     tcc_delete(s);
     return 0;
}
