How do you get assembler output from C/C++ source in gcc?

Question

How does one do this?

If I want to analyze how something is getting compiled, how would I get the emitted assembly code?

I don't see this possibility among answers, probably because the question is from 2008, but in 2018 you can use Matt Goldbolt's online website https://godbolt.org

You can also locally git clone and run his project https://github.com/mattgodbolt/compiler-explorer
