C-Vise is a super-parallel Python port of the C-Reduce. The port is fully compatible to the C-Reduce and uses the same efficient LLVM-based C/C++ reduction tool named clang_delta.

C-Vise is a tool that takes a large C, C++ or OpenCL program that has a property of interest (such as triggering a compiler bug) and automatically produces a much smaller C/C++ or OpenCL program that has the same property. It is intended for use by people who discover and report bugs in compilers and other tools that process C/C++ or OpenCL code.

mold is a faster drop-in replacement for existing Unix linkers.
It is several times faster than LLVM lld linker, the second-fastest
open-source linker which I originally created a few years ago.
mold is created for increasing developer productivity by reducing
build time especially in rapid debug-edit-rebuild cycles.

MeshLab is designed for the processing of typical large unstructured models arising in 3D scanning, providing a set of tools for editing, cleaning, healing, inspecting, rendering and converting this kind of meshes.
