Re: Dumping Gimple After Optimization

[Mostafa Shahto <mshahto at gmail dot com>]

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.
Btw, Thank you Andrew
Thank you,
