I've just run some analyses of C and C++ optimization in gcc 3.4 (20030806). Given my use of a 3.4 snapshot, I added the -funit-at-a-time option to my analysis. Before presenting my results, I hope to receive answers to a couple of questions.
What else is new in 3.4 that I should be aware of?
I note that the SSA switches are still listed as "experimental"; does anyone recommend that I include those switches in my analysis or not?
What about -fnew-ra, -ftracer, and other options rarely discussed (and probably unknown to most gcc users)?
It would be quite helpful if future documentation listed the default values for the various --param switches; such values can often be difficult to discern in the source code.
Thank you in advance.
