Hi, fellow GCC developers!
I was wondering if the "gcc" driver could be made to invoke
"cc1" twice, with different flags, and then just keep the
better of the two .s files that comes out?
I'm sure this is not a new idea, but I'm not aware of
anything being done in this area, so I've made this pos

Please hold off on GCC 4.8.3. powerpc-linux has a

and shortly its mirrors. It has been generated from SVN revision 210453.

Thanks for the reply. I will look at the patch. As far as the cost is
concerned, I think fwprop doesn't really need to understand pipeline model. As

I had a C++ program that crashed, so I added debug output using clog.
Unfortunately the first out put to clog also crashed within iostreams.
