I've never heard of this. It's a pity the article doesn't go into details.

It claims clang is NOT "a pipeline that runs each pass of the compiler over your entire code before shuffling its output along to the next pass."
What I think the author is talking about is primarily AST parsing and clangd, where as "any compiler tome" is still highly relevant to the actual work of building a compiler.
E.g. "Integer Comparison is not Deterministic", in the C standard you can't do math on pointers from different allocations. The result in the article is obvious if you know that.
Also, in the Logistic Map in 8-Bit. There is a statement
> While implementing Algorithm 1 in modern systems is trivial, doing so in earlier computers and languages was not so straightforward.
Microsoft BASIC did floating point. Every 8-bit of the era was able to do this calculation easily. I did it on my Franklin ACE 1000 in 1988 in basic while reading the book Chaos.
I suppose what I'm saying is the premise of the articles seem to be click-baity and I find that off putting.
