>Environment:
System: Linux alps 2.4.19 #3 Mon Nov 25 10:57:02 MET 2002 alpha unknown
Architecture: alpha

host: alphaev5-bruli-linux-gnu
build: alphaev5-bruli-linux-gnu
target: alphaev5-bruli-linux-gnu
configured with: ./configure --prefix=/usr --exec-prefix=/usr --host=alphaev5-bruli-linux --enable-threads=posix --enable-shared --disable-static
>Description:

	Compiling glibc-2.3.1 using -mcpu=ev5 generates code that does
	not run correctly on alpha/ev5. 
	Compiling ssh-3.1 using -mcpu=ev5 generates code that does not
	run at all.

>How-To-Repeat:

	Compile the source using -mcpu=ev5 on a ev5 machine and try
	to run this code.
>Fix:

	Using -mcpu=ev4 generates runnable code. (The advantages of
	the ev5 over the ev4 is lost).
