Probably no. I think when you reach some level of understanding, you'll use manuals. Then you know what you're looking for. :)

- acdimalev 10y agoAnd once you start reading the docs on the more efficient but far less consistent 64-bit calling convention, you may find yourself choosing words to describe it other than the "improved" that this author opted for.
- aktau 10y agoI take it you're a fan of the plan9 calling convention (f. ex.: all arguments and return value(s) are on the stack)? Curiously, it doesn't actually appear all that ineffecient. Go uses it AFAIK. I wonder whether anyone has studied it. I also wonder whether gccgo uses that convention or defaults to SysV x64.
- acdimalev 10y agoI didn't know it was a System V thing. Thank you for cluing me in! I don't think of it in terms of like-vs-dislike. My observation is that it's a difficult thing to get right without a compiler, and thus avoided for introductory material. As far as I am aware, storing values in a register requires fewer instructions. However, I have never personally confirmed the performance difference of this calling convention. Handling of all calling conventions is one of the many things that I am personally much happier leaving up to GCC and LLVM in practice.
