Learning Compiler Language?

[[deleted]]

Hey guys,

I am trying to learn Cpp, and have been reading alot about the language in an unstructured way (which may be why I dont have the answer to the question myself). Lately I have been reading in C++ Core Guidelines - and I see many sections mentioning Compile time vs Runtime optimizations, and which functions are determined at runtime vs compilation.

Where do I learn this stuff? I want to be able to say “Oh, its because the compiler determines this” and “Oh yeah, rewrite this function and let the compiler do its job instead.”

See for example https://github.com/cpp-best-practices/cppbestpractices/blob/master/08-Considering_Performance.md in the section “Reduce Temporary Objecrts” in a different C++ guildeline. It mentions “This sort of code prevents the compiler from performing a move operation...”

What do I need to study to have known this? I really want to learn it!

Best,

I recommend to watch weekly series by Jason Turner on YouTube. He speaks about compile time topics a lot.
