	lal	$1,  $2($1)')

dnl  Usage: ALIGN(bytes)

dnl

dnl  Unicos assembler .align emits zeros, even in code segments, so disable

dnl  aligning.

dnl

dnl  GCC uses a macro emiting nops until the desired alignment is reached

dnl  (see unicosmk_file_start in alpha.c).  Could do something like that if

dnl  we cared.  The maximum desired alignment must be established at the

dnl  start of the section though, since of course emitting nops only

dnl  advances relative to the section beginning.
