-<p>These posts explain how to handle CPU exceptions using naked functions.
-  Historically, these posts were the main exception handling posts before the
-  <code>x86-interrupt</code> calling convention and the <code>x86_64</code> crate existed.
-  Our new way of handling exceptions can be found in the
-  <a href="/handling-exceptions.html">“Handling Exceptions”</a> post.

-  <p>In this post, we explore exceptions in more detail. Our goal is to print additional information when an exception occurs, for example the values of the instruction and stack pointer. In the course of this, we will explore inline assembly and naked functions. We will also add a handler function for page faults and read the associated error code.</p>

 The [GNU Binutils] are a collection of various binary tools such as `ld`, `as`, `objdump`, or `readelf`. These tools are platform-specific, so you need to compile them again if your host system and target system are different. In our case, we need `ld` and `objdump` for the x86_64 architecture.

 If you get an `error: can't find crate for 'core'`, you're probably compiling for a different target (e.g. you're passing the `target` option to `cargo build`). Now the compiler complains that it can't find the `core` library. This document gives a quick overview how to fix this problem. For more details, see the [rust-cross] project.

 There are a lot of things that can go wrong when developing an OS. So it's a good idea to add a debugger to our toolset, which allows us to set breakpoints and examine variables. We will use [GDB](https://www.gnu.org/software/gdb/) as QEMU supports it out of the box.
