These look more like configure snapshots for Zig's bundled Clang than full ports of build system. The HAVE_/WITH_ defines are supposed to be dynamically probed to adapt to differen…

It did take many hours, but I learnt a lot in the process, found some bugs to report, and watched plenty of series concurrently. Overall it's a nice and worthwhile hobby!

For those who are making indie C compilers that don't pretend to be __GNUC__ but want to compile real world projects, slimcc's test script[1] and platform header hacks[2] might sav…

The page says "aims to provide 70%" though, funny how words spread.

There is a library conversion fork: https://github.com/sgraham/sqbe . IMO when the intended usage is AOT with an external assembler, which is another subprocess, text-based IO is a…

Some of us do spend hours on godbolt.org tweaking code like it was game character build.

That read like a supply-chain attack gold mine if you ask me.

rcc[1] is another real-JIT C compiler. antcc[2] and xcc[3] are worth mentioning for being fast-enough to run C like scripting. [1] https://github.com/dstogov/rcc [2] https://codebe…

Looking at the repo, the author seemed a little fed up [1] with the nature of lower level language and quitted. [1] https://github.com/asibahi/paella/blob/main/writeup/c19.md#u...

Yeah, to get arcane macro tricks right I probably spent more than a full month total fighting with linked lists, never want to touch that part again.

Can't speak for kefir; slimcc has been `make unittest`ing Neovim v0.10.4 with no source modification in a Debian VM (so it's pretty portable, thanks!) On tcc, the most common dealb…

c-testsuite itself was curated from simple-cc and tinycc's test files, the latter originated from picoc.

I have found portability bugs in many projects with slimcc just because it exposed different preprocessor defines, some gate critical __attribute__ behind __GNUC__ check, some have…

Congrats for the new optimizing pipeline, and thanks for the acknowledgment! It's nice to have company in the non-__GNUC__ camp.

TinyCC's mob branch on repo.or.cz just got trolled with AI commits today. Nowhere is safe it seems.

I don't fully grasp it either, the most appropriate analogy I can think of is like how OpenMP turns #pragma annotated loops into multi-threading, this work turns bytecode interpret…

Took me a while to figure out whether it's interpreters for C programs or if there's a particular class of interpreters called "C". Turns out it's about interpreters implemented in…

The website you linked says mallocng?

Don't get mimalloc and mallocng mixed up though, completely different animals.

Thanks, that actually look like a very solid baseline to start things with. Are you aware of onramp[1]? They use a custom VM to base compiler and shell on, it's extra steps, but co…

Well, I happen to have been recreationally maintaining a hobbyist C compiler for three years, adding tests is part of the fun.
