Ah - you are using c++.
My project is c, which is why I can use tcc.
Anyway, that makes sense; in c++, there's a lot of 'extra' stuff, single lines of code that add up to much more than they would seem. I bet -O1 lets the compiler inline a lot of std::move, smart ptr semantics; elide monomorphisations, copy constructors/RVO; etc. Which just means less code to spit out the backend.
- fluffything 6y agoAh right, for some reason I thought you were talking about C++. Yes for C what you mention makes perfect sense. I agree with you about C++ as well. In particular, C++ templates end up expanding a lot of duplicate code, and at O1 the compiler can remove them.
