How does Clang align the frame pointer? What happens if the function uses
Hi,
I was looking at the implementation of mstackalign in gcc (O2/O3) and it
looks like we generate code for mstackalign (i.e. generate instructions for
stack alignment) before pushing $rbp to stack/setting $rbp. In the
epilogue, we do the same in reverse order.
