As a sidenote: it is insane that I am now referred to as "performance focused." If you'd told someone at RAD to "go talk to the performance guy", they would literally go to every other office _but_ mine. I was easily the least performance-focused person there!

Modern compiler will do it better than you. Write in C :)

100% false. While you can usually still use C, if you can't read the ASM that gets generated, you will get hurt all the time by very bad codegen and not know. I encounter a horrendous LLVM codegen bug at least once every LLVM version, and it seems to be getting more frequent.

This is 100% false because you found some bug in the compiler? Give the impression to a beginner ASM programmer that he will always write better ASM than the compiler is a really bad advice. 1/2

I am happy to revise it to 99.9% false if you would prefer. The person asked for a book on ASM. Someone told him to "just code in C". I think that's 100% false advice, or 100% "bad" advice, etc. Nobody said anything about "always producing better code than a compiler".

I interpret the "100% false" referred to the "Modern compiler will do it better than you" part of the tweet.

Well, that was definitely not my intent, since that doesn't ever matter in practice - you can always just look at the output of the compiler and see if it's better or not before you write it in ASM. I'm not sure why that would even be a concern.
