Re: [gem5-users] [gem5-dev] GCC Compatibility Issue
Dear Liang, I recommend to use the latest version, as you can be up to date with bug fixes and new features (and even patch some). You should find "documentation" all over the internet (jason's tutorial: http://learning.gem5.org/book/index.html, stack overflow: https://stackoverflow.com/questions/tagged/gem5, Gem5 papers, gem5.org, the mailing list, tracking back the commits that introduced the feature that you want to know about...), but indeed there's no easy way, and you will end up recurring a lot to trial and error.
