I believe what you are looking for is the -taso option.  It was added to
the linker in binutils version 2.9.5.0.24.  I have not been able to
confiirm via net searches if/when it was added to GCC. (My alpha's
in pieces still following a move from Portland to Phoenix.)  I have
seen mention that it has been added to the gcc code, but not added
to the documentation.  You may want to try compiling with it and
see what happens.  I would not be surprised if the resulting
binary halts the box... ;-)
