FAQ |
bfc is an LLVM-based compiler that converts Brainfuck to native code.
It's a legitimate BF implementation with genuine compiler optimisations. bfc has been referenced on Wikipedia and the llvm-sys docs.
bfc is also a toy. I'm always pleasantly surprised when people find actual uses for it.
I believe it's the second fastest BF compiler. Mats Linander's BF optimisation research project is still faster on many programs.
BF is a really good language for learning about compilers. With only eight operations, it's way more feasible to build elaborate features like speculative execution and instruction reordering. Also, it's fun.
bfc is licensed under GPLv2 or later. Documentation (files ending .md or .png) is licensed under CC-BY 4.0, and Twemoji images are also CC-BY 4.0.
Sample programs are largely written by other authors and are under other licenses.
It's a gingerbread man with BuFfalo plaid. I felt it captured the silliness of the whole project.
The unfortunate name of brainfuck is discussed on the esolangs wiki. Some writers even use the term "the unmentionable programming language".
To avoid confusion (and help search engines), I use the term "brainfuck" on introductions, such as the home page. In other cases I use "BF".
Many! Some noteworthy examples I've seen are:
