Top 8 C++ llvm-ir Projects

llvm-tutor

1 2,710 6.0 C++

A collection of out-of-tree LLVM passes for teaching and learning
remill

3 1,177 6.4 C++

Library for lifting machine code to LLVM bitcode

Project mention: Revng translates (i386, x86-64, MIPS, ARM, AArch64, s390x) binaries to LLVM IR | news.ycombinator.com | 2024-01-12

Usually such things are called lifters. Wonder how this tool compares to other existing LLVM IR lifters, such as remill[0] and rellume[1].

alive2

4 675 9.3 C++

Automatic verification of LLVM optimizations

Project mention: Basic SAT model of x86 instructions using Z3, autogenerated from Intel docs | news.ycombinator.com | 2023-05-15

You can use it to (mostly) validate small snippets are the same. See Alive2 for the application of Z3/formalization of programs as SMT for that [1]. As far as I'm aware there are some problems scaling up to arbitrarily sized programs due to a lack of formalization in higher level languages in addition to computational constraints. With a lot of time and effort it can be done though [2].
