The source code is available [https://github.com/iacgm/c2bf on Github], and a write-up explaining the implementation and its limitations is available [https://iacgm.pages.dev/posts/c2bf here]. C2BF supports, among other features: * if-statements, while-loops, for-loops * arrays * functions * pointers * function pointers =Implementation= C2BF compiles C code to a stack-based intermediate language, so that each instruction can then be translated into a [[Brainfuck]] snippet. For example, putchar('0' + 5); ... is compiled into the sequence: Push(48) Push(5) Add PutChar Then, each of these is translated into Brainfuck (the convention is that each instruction begins execution pointing at the top of the stack, which grows rightward, and that all cells to the right of the tape head are zero): Push(48) --> ++++++++++++++++++++++++++++++++++++++++++++++++ Push(5) --> +++++ Add --> [-<+>]< PutChar --> .[-]< For control flow, the IR is split into basic blocks, and the entire program is placed in a [] loop. See [https://iacgm.pages.dev/posts/c2bf] for more details about the implementation and its limitations. [[Category:Compilers]] [[Category:Brainfuck]]'
