Ever wondered what your C code compiles to? Yes, you can use gcc -S, but finding your function and comparing it to your original code can be a pain in the "S". So try this:

http://gcc.godbolt.org/

My only little gripe with it is that it doesn't optimize well at all, and adding -O3 breaks it.

I'd add anaconda to the list of IDEs - even though its more than that.
Platform: Windows/OSX/Linux
See: www.anaconda.com

A fully featured python environment, complete with the Spyder IDE (which I think is a pleasure to work with).
Also works with R, but I've never had cause to use it.
