Hi, I have a requirement where I'm writing N bytes of data to a buffer. If the
last byte after data is not aligned on 8-byte boundary, I need to add some
padding after data.
So assume 'buffer' is a pointer to a buffer, after putting N bytes of data in
the buffer the pointer will be incremented by N. Is the following code correct
for aligning a pointer on 8-byte boundary? Will it work correctly with 64-bit
addresses, or do I need to cast -8 to 64-bit value in that case?
buffer & -8
