AVR

Quite a while ago, I’ve integrated my exceptions work into a fork of GCC. At that point, I was already modifying GCC to suppress the libunwind symbols, so putting all of my code into GCC was a no brainer. Moreover, it isn’t actually that hard to build GCC. Editing GCC GCC is built via the autoconf build system. Autoconf is a collection of scripts that is somewhat like CMake, but written entirely in shell script and is intended to be portable for any system that runs shell scripts and has a C compiler....

For the past couple months, I’ve been trying to get exceptions to work on AVR as a hobby project. After several months of work, I’ve done it. Exceptions work, you can just include <vector> and it just works. How to use it Currently I put prebuilt toolchains on github. My changes are currently a bunch of patches to gcc 13.2.0, binutils, and a few others. What I actually did I’ve reimplemented libunwind, the personality function, and also cfi macros by replacing them with my own stuff....
