Following some hints from Samuele, I am trying to wrap such functions in another function that does some casting.
Here is the latest: def softwrapper(funcptr, arg_tps): unrolling_arg_tps = unrolling_iterable(enumerate(arg_tps)) def softfunc(*args): real_args = () for i, tp in unrolling_arg_tps: real_args = real_args + (args[i],) result = funcptr(*real_args) return result return softfunc When applied to llexternal's that have pointer-to-struct args the generated c code breaks; it decides to declare&use anonymous structs: long pypy_g_softfunc_star2_1(struct pypy__cairo_surface0 *l_stararg0_7, struct pypy_array3 *l_stararg1_7) { long l_v492; block0: l_v492 = cairo_surface_write_to_png(l_stararg0_7, l_stararg1_7); goto block1; block1: RPY_DEBUG_RETURN(); return l_v492; } where cairo_surface_write_to_png is declared: cairo_surface_write_to_png (cairo_surface_t *surface, const char *filename); I wonder if the annotator is getting confused by the real_args tuple growing...
