Fun project and good learning goal

I will always upvote something like this, but I am wondering: why write it in C++? I didn't really read the whole thing, but I skimmed a bit, and didn't see a lot of advantage…
pmiller2 on HNkudos to you, this is something I don't think I could ever accomplish but I know it's not easy. Keep learning and growing.
warmwaffles on HNThis is awesome. Thank you for sharing it with us. :)

Code base looks clean and easy to navigate
From 1 comment
The code base looks nice and easy to navigate. I didn't see any license mentioned - I'd suggest stating one clearly for those considering to build something on top of it, or to…

Objections
Written in C++ rather than C, which prevents self-hosting

pmiller2 on HNI would completely agree with you if this weren't a C compiler project. In this case, the advantage of having a self-hosting compiler is huge! Among other things, you can use the…

No license stated, so it is not free software
From 2 comments
Can you please add a free software license to your project, as it's currently proprietary? I'd recommend GPL, but go with whatever you want. Contrary to popular opinion,…

Automatic parallelisation is a poor idea
From 1 comment
Automatic parallelisation is a bad idea because the overhead caused by synchronisation is bigger than the gain. It's also a bad idea to take away control from the programmer.…

Suggestions for test suites such as gcc testsuite, csmith, or tcc tests
From 4 comments
Where does one go for a fully representative sample of all kinds of valid C code to test a project like this? Or -- given a formal grammar, has someone produced a tool that…
m1n1 on HNFor specific test cases, you could use gcc's test cases: https://github.com/gcc-mirror/gcc/tree/master/gcc/testsuite Not sure about the latter, but you could probably accomplish…

moosingin3space on HNFor gradual implementation I would start from a test suite in tcc [1]. Eventually adopting the one from gcc and csmith. [1] http://bellard.org/tcc/

Questions
Why use a generated parser instead of recursive descent or precedence climbing
From 1 comment
I'm curious to know your reasoning behind using a generated parser instead of writing your own. This might be the first "just for fun" C compiler I've seen on HN or elsewhere…

pmiller2 on HNI was wondering the same thing... ?? Oh, and you get an upvote from me too.

Seems like the ETH work on Oberon etc did that. The students kept learning by improving on or porting both the compilers and OS's. A2 Bluebottle is a fast, usable OS as a result.…

Actually the bugs they found in CompCert were not in the proved sections. The CSmith paper says "As of early 2011, the under-development version of CompCert is the only compiler…
