I checked in the patch. But it is not complete. If the alignment
directive is a no-op, the stop bit will be missing.

[hjl@gnu-2 alloc]$ cat no.s
        nop 1
        .align 16
.L481:
        alloc r2 = ar.pfs, 0, 0, 1, 0
[hjl@gnu-2 alloc]$ ./as -o no.o no.s
[hjl@gnu-2 alloc]$ objdump -d no.o

no.o:     file format elf64-ia64-little

Disassembly of section .text:
