I did not and will not run this on my computer but it looks like while loops are totally broken; note how poor the test coverage is. This is just my quick skimming of the code. Maybe it works perfectly and I am dumber than a computer.
Regardless, it is incredibly reckless to ask Claude to generate assembly if you don't understand assembly, and it's irresponsible to recommend this as advice for newbies. They will not be able to scan the source code for red flags like us pros. Nor will they think "this C compiler is totally untrustworthy, I should test it on a VM."
Are you concerned that the compiler might generate code that takes over your computer? If so the provided Dockerfile runs the generated code in a container.
Regarding test coverage, this is a toy compiler. Don't use it to compile production code! Regarding while loops and such, again, this is a simple compiler intended only to compile sort and search functions written in C.
