Subject: gcc 3.4 and -O4/-O5
X-SW-Source: 2003-11/txt/msg01227.txt.bz2

    Does anyone know what the status is of optimizations 
above -O3 in gcc 3.4? Are there really any done at
-O4 or -O5? Also since I am using mainly g77 at the moment
I guess they would have to be in the backend of the
compiler to have any effect. Thanks in advance for any
information.
