We just released a tiny (~3kloc) Python library that implements state-of-the-art inference algorithms on GPU and provides performance similar to vLLM. We believe it's a great learn…

Hi, thanks for the information, but LLVM still does not provide ABI compatibility. If you reduce the struct to 3 i32, it is passed in edi, esi, and edx on my machine. However accor…

I actually decided to take more time to answer your comment more throughly than others. Also, I TA'd twice the class from where you linked the article below, so I know about it :).…

It's only a goal I set to myself, if we can do better, heck let's do it! Keeping the code short, on the other hand, is really something I care about.

I think the extra load/stores clutter the IL. Also, QBE does not really "alternate" SSA/non-SSA, SSA form is built once at the beginning of the compilation pipeline and preserved l…

Cool, thank you guys!

At least, I can try! And also, we are seeing more and more certified C programs: see the DeepSpec NSF expedition grant, the Verified Software Toolchain, and the CertiKOS project fo…

I take this as a compliment. It means my design choice was totally valid, and maybe even a good one.

Then maybe I did not express myself in the best terms. QBE definitely supports stack slots and their registerization! Minic, a small C frontend shipped with QBE makes use of them. …

It's an alternative if you fit in the use case. I did not try to clone LLVM.

It's much much smaller (I think libfirm is over 100kloc, QBE is about 6k). But the major difference is the IL: I use a human-readable and easily-printable text IL. This means that …

Thank you for your words. It is often called NIH, but eh, I learned a lot! And I think that I made some modest improvements over LLVM, you can check them out in my comparison at ht…

12,000 links is probably too much.

Hurray, no floating points!

So you rewrote the whole thing.

You're wrong about the arrays, the standard guarantees that zeroing the bytes of an object of integer type will give a 0 value to the integer. Pointers are a different matter thoug…

Bullshit, on x64 all 32 or 64 bit base arithmetic operations have the exact same cost, except the 64 bit version is one byte longer because of a REX prefix. This is why 32 bits is …

Do you realize you do exactly what you say shouldn't be done? You just defined "a good place to start" by negation. Idiot.
