In tree_expand_cfg, we have:
if (DECL_NAME (current_function_decl)
&& MAIN_NAME_P (DECL_NAME (current_function_decl))
&& DECL_FILE_SCOPE_P (current_function_decl))
expand_main_function ();
This code should also check TREE_PUBLIC (c_f_d) (and the entire predicate
should probably be encapsulated in a macro or function).
Compiling this test case:
extern void f();
static int main () {
f();
}
int g() {
f();
}
on x86_64-unknown-linux-gnu with -m32 shows that the usual stack-alignment and
implicit return of zero code is generated for this "main" function, even though
it's not the real main function.
