Ok, this is more or less what I though. I guess that nobody want unoptimized code in his final build, so I think I can go with my hack (adding -O1 when needed). > Also, future versions of GCC may not have > this phase as the final phase, or the dump file name may change, or both. > > Dump files are merely debugging aids.

Hum, I'm coding a tool for static and (symbolic) dynamic analysis of code, would you recommend me a way to get the most final CFG you get inside GCC (other than the -fdump-tree-<flags>) ??? It would be very helpful for me to get a GENERIC/GIMPLE CFG (with SSA and so on) of the source code so that I can analyze all the languages that go through a gimplifier. :-/ >> A final remark, not really significant, I noticed that since gcc 4.2, >> the name of the dumped tree files have slightly changed.

I'll dig this. :) Actually, I know that these dumps are here, as you said, just for debugging purpose but why not making them 'permanent' and kind-of 'standardized' (I mean, not changing it too frequently), so that code analysis tools could plug on GCC ?
