1. This is the gzipped version of the "tar" archive of gcc-2.7.1 and binutils.2.5.2 modified to perform code partitioning. 2. The file can be expanded by executing the command "gunzip --stdout gcc.tar.gz | tar xvf -" 3. After the archive is expanded, it will create the source files under the tree rooted at "gcc". The top-level directory has a README and a README.INSTALL file explaining the installation procedure and details of how to compile and run a program with this compiler.
