American Fuzzy Lop VS clangd

There's some efforts to guide test generation for property based testing to make the instruction pointer explore as large a space as possible.

This effort is more mature in the fuzzing community. See eg American Fuzzy Lop https://github.com/google/AFL

What you're describing, just generating random input to test a program, is sometimes called "blind fuzzing" but the state-of-the-art is far beyond that. Maybe try reading through the documentation of e.g. https://github.com/google/AFL to see what a fuzzer does and why just producing random input isn't even scratching the surface.

for general riscv I used to use this https://github.com/google/AFL I dont know if it supports x64 tho.

Ex ( AFL, WinAFL, HonggFuzz, LibFuzzer, Jazzer )

I wrote this little fuzz test target in order to fuzz it with afl (under ASan and UBSan):

afl, which is trivial to apply to this program:

I made my own version of a TCL interpreter (well, a very TCL like langauge) derived from "picol" available at https://github.com/howerj/pickle. There are many different re-implementations and derivatives of this interpreter but they all seem very "crashy", this one has been significantly hardened by using a fuzzer on it which ran for months called American Fuzzy Lop https://lcamtuf.coredump.cx/afl/ . It is also more suitable for embedded use whilst still not having arbitrary restrictions like many other implementations.

On Linux afl is a very powerful bug-finding tool, and it's a great companion when doing code review. Composes well with ASan and UBSan.

I'm still waiting for clangd support, e.g. [0] before trying modules.

I know one way to do this, but hoping there's something simpler or more general. clangd (C++ LSP server) is over-aggressive about adding "helpful" #includes during completion. The way to turn that off is to pass -header-insertion=never on its cmd line.

Install the clangd language server using your system package manager, e.g. sudo apt-get install clangd

> As a side note, I despise things like imports and aliases. I'd prefer that when I do jump to a function, I can read it without having to check if anything is imported or not.

One idea might be to use an LSP (Language Server Protocol) interface. It could describe the fully qualified symbol for you when you, say, select the abbreviated symbol or press a keyboard shortcut. I've been working on a moderately large C program with Emacs and clangd[1] recently and have been amazed at how 'immersive' it feels, and that's from someone who's used to the comfort of a Lisp REPL!

FWIW, recent clangd also has this feature: "unused" as of 14, "missing" as of 16, works better in snapshots.

You need to install CMake (and use it to build your project - which you should do in any case) and clangd.

First we would need the Clangd extension as well as the LSP itself You can download the extension from #here The extension provides its own Clangd LSP but in case of issues with that we would like to download and setup the clangd package from the official site for both Windows and Linux I daily drive Linux on my laptop, thus this guide works well for linux users, Windows users can use programs like Cygwin to replicate the process

Few days ago I found a bug while using clangd LSP with neovim, and submitted a bug report to clangd: https://github.com/clangd/clangd/issues/1640

Come to the light side: VSCodium with clangd
