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.
