A basic converter ("transpiler") from brainfuck to assembly

(x86-64, System V AMD64 ABI compliant).

Makefile rules

• all: produces the binary
• debug: prudes the binary with the debug files
• check: starts the test suite with criterion for unit tests, and pytest for functional ones with brainfuck-interpreter as a reference (from here: https://pypi.org/project/brainfuck-interpreter/).
• clean_objs: removes all *.o files
• clean: removes all of the produced files

Usage of the binary

• Convert from a file: ./bf file
• Convert from a string: ./bf -c "[code]"
• Convert from stdin: echo "[code]" | ./bf

Once the output.S is generated, you can compile it with gcc check.c output.S.

TODO:

• Add the reading on stdin.
• Add tests using ','.
• Optimize multiple identical operations into a single one (72 * '+1' becomes '+72'...).
