Indeed, function descriptors are a difference between the ABIs as well:
On powerpc-aix and powerpc64-aix, a function pointer is actually a pointer to a
struct {
void* code_address;
void* toc_pointer; /* gets loaded into register r2 */
void* static_chain; /* gets loaded into register r11 */
}.
Likewise on powerpc64-linux (but not on powerpc-linux and
not on powerpc64-elfv2-linux!).
