I made a BF compiler that goes really fast. I'm in a compilers class right now and for whatever reason my professor has gotten severely nerd snipped into building the fastest BF compiler in the world.
Mine is pretty darn fast; it compiles to native ARM assembly and can generate a Mandelbrot set in less than 0.5 seconds on my M1 Pro machine. Full writeup (with links to source) here: https://lambdaland.org/posts/2024-10-22_bf_writeup/
A while ago I wrote a Zig brainfuck implementation[1] that converts Brainfuck code into an executable function at comptime. The performance is similar to transpiling the code to C and compiling it with full optimization settings.
