103dnl  Usage: ALIGN(bytes)
104dnl
105dnl  Unicos assembler .align emits zeros, even in code segments, so disable
106dnl  aligning.
107dnl
108dnl  GCC uses a macro emiting nops until the desired alignment is reached
109dnl  (see unicosmk_file_start in alpha.c).  Could do something like that if
110dnl  we cared.  The maximum desired alignment must be established at the
111dnl  start of the section though, since of course emitting nops only
112dnl  advances relative to the section beginning.
