> My favorite project along those lines is Kartik Agaram's Mu[3], which wraps emulation, tracing, and time-travel debugging around a subset of x86 assembly language. From https://akkartik.name/code : Mu[1], a safe, hackable computing stack that builds up from raw machine code (guided tour[2]; paper '20[3]; talk '20[4]; sample app[5]) [1] https://github.com/akkartik/mu [2] tour https://github.com/akkartik/mu/blob/main/tutorial/index.md [3] paper https://akkartik.name/akkartik-convivial-20200315.pdf [4] talk https://vimeo.com/416363066 [5] sample app https://archive.org/details/akkartik-mu-2021-08-15

Note that Matt Keeter has been at this for quite a while now, very generously sharing his efforts and research: https://www.mattkeeter.com/research/ In particular, his thesis is well-worth reading: https://www.mattkeeter.com/research/thesis.pdf

I also made a SDF editor, with different goals. It's WebGL-based for pasting code from ShaderToy and can export STLs for 3D printing. https://sdf2stl.saej.in/
