We’ve now learned quite a bit of ARM 64-bit Assembly Language; one of the things we can do is read another programmer’s code. Reading another programmer’s code is a great way to not only add to our toolkit of tips and tricks but also improve our own coding. We’ll review some places where you can find Assembly source code for the ARM processor. We’ll examine one of the Assembly Language routines from the Linux kernel to learn some new optimization techniques. Then we’ll look at how the GNU C compiler writes Assembly code and how we can analyze it. We’ll look ...
