#2Old, well-known feature of one of the most popular languages. I must be missing something, because I have no idea how this became a hacker "news" :)

#3I don't see anything on that page referencing C++20. Am I missing something?
On a related note, I always find the official docs for GCC inline assembly are insufficient for figuring out what I am trying to do. I nearly always have to resort to dumb trial and error. I was just recently planning to write some docs of my own on the subject. Not tutorial docs, but reference docs.

#4Odd bit of news reporting on something that was part of a standard published in 1997. What's next, breaking news on a standard 7-bit code used by Americans for information interchange?

#5I was a Forth dev a long time ago (on a planet far away...). Switching to & from assembly seemed as natural as breathing. Oh for the days of 16bit cores and minuscule register banks.

#6Lots of languages have inline assembly. Pascal does:
- Free Pascal: https://www.freepascal.org/docs-html/prog/progch3.html#progs...
- Delphi: http://docwiki.embarcadero.com/RADStudio/Rio/en/Inline_Assem...
You can even do assembly in batch files via Debug if you really want to:

#7did this in college over 10 years ago..

#8Maybe what's new here is the suggestion of using a raw string literal for the assembly source? That does look neat (if minor).

D has a very nice inline assembler (assuming you're on a supporter platform, if not then you get to use the standard gnu style)
