I've tried -fdump-tree-all before, and yes, I'm getting different types of files, including Gimple. But in the gimple file, there is no Copy Propagation Optimization or CSE. How can i get an optimized (all possible optimizations) gimple file or gimple-like file?? I'm new to developing under Linux, so regarding you advice, I've run the following command (my C++ file is mm4x4.cpp): $gcc mm4x4.cpp -fdump-tree-all tmp.c -o mm4x4 But i'm getting an error about tmp.c. Is this what Andrew ment with tmp.c? or does tmp.c stand for something else? Because I really need the SSA file too.
if you do gcc mm4x4.cpp -fdump-tree-all -o mm4x4, you should get a bunch of files named mm4x4.cpp.<dump file number>.<pass name> Most passes dump the IR as it looks after their pass. Any of the passes in the middle are dumps that are in SSA form.
