As seen on http://gcc.gnu.org/ , the currently maintained release branches are 4.4, 4.5, and 4.6. 4.3 is no longer maintained. > Are there some fixes applied in 4.5/4.6 which are not applied to 4.4 ? > So what is "right" branch to use so for my backend port ? My general rule is: if you plan to contribute the backend port to mainstream gcc, you should use current mainline; if you plan to keep the port private, you should use the most recent release branch and upgrade to new release branches after the first release is made.
