Strange assembler-comments with -fverbose-asm

Strange assembler-comments with -fverbose-asm

[KRECKEL Richard NGLT]

Hi,

GCC 3.3.x with targets i386-{aout|coff} and possibly others generate wrong
comments
when called with -fverbose-asm.  Here is how to reproduce:

---<test.c>-----------------------------------------------------------------
------
int noop( int i )
{
    return i;
}
---<test.s>-----------------------------------------------------------------
------
        .file   "test.c"
/ GNU C version 3.3 (i386-aout)
/       compiled by GNU C version 3.1.1.
/ GGC heuristics: --param ggc-min-expand=55 --param ggc-min-heapsize=48115
/ options passed:  -D__GNUC__=3 -D__GNUC_MINOR__=3 -D__GNUC_PATCHLEVEL__=0
/ -auxbase -fverbose-asm
/ options enabled:  -fpeephole -ffunction-cse -fkeep-static-consts
/ -fpcc-struct-return -fgcse-lm -fgcse-sm -fsched-interblock -fsched-spec
/ -fbranch-count-reg -fcommon -fverbose-asm -fargument-alias
/ -fzero-initialized-in-bss -fident -fmath-errno -ftrapping-math -m80387
/ -mhard-float -mno-soft-float -mieee-fp -mfp-ret-in-387 -mcpu=i386
/ -march=i386

        .text
.globl _noop
_noop:
        pushl   %ebp
        movl    %esp, %ebp
        movl    8(%ebp), %eax   /  i
        leave
        ret
----------------------------------------------------------------------------
------

That comment in the third line of the function should be introduced 
by a '#', as opposed to by a '/'.

Here is a short way how to reproduce the problem, given gcc compiled with
--target=i386-aout and a corresponding as from binutils 2.14:

$ i386-aout-gcc -fverbose-asm -c test.c -v

--traditional-format -o test.o /tmp/ccIfergm.s

Looks like a bug, doesn't it?
