+Different targets are built in different subdirectories of m5/build.
+Binaries with the same target but different optimization levels share
+the same directory. Note that you can build m5 in any directory you
+choose by copying the SConstruct file there and creating symbolic links
+to the 'm5' and 'ext' directories.

+The following steps will build and test the simulator. The variable
+"$top" refers to the top directory where you've unpacked the files,
+i.e., the one containing the m5, m5-test, and ext directories. If you
+have a multiprocessor system, you should give scons a "-j N" argument (like
+make) to run N jobs in parallel.
+
+To build and test the syscall-emulation simulator:
+
+1. In $top/m5/build, run "scons ALPHA_SE/m5.opt".
+2. In $top/m5-test, run "./do-tests.pl -B ALPHA_SE".
+
+The tests should end with "finished do-tests successfully!"
+Note: if you're running under Cygwin several tests will fail with an
+"EIO icount mismatch". This is due to the lack of fesetround() under
+Cygwin causing differences in floating-point rounding.
+
+To build and test the full-system simualator:
+
+1. Download the full-system binary package from XXX. This package includes
+ disk images and kernel, palcode, and console binaries for Linux and FreeBSD.
+2. Edit SYSTEMDIR in $top/m5-test/SysPaths.py to point to your local copy
+ of the binaries.
+3. In $top/m5/build, run "scons ALPHA_FS/m5.opt".
+4. In $top/m5-test, run "./do-tests.pl -B ALPHA_FS".
