linux – 如何格式化汇编注释

我有以下示例评论GAS代码

cmpb $45, (%ebx)  # 45 - ASCII '-'
jne r_filename
cmpb $118, 1(%ebx) # 118 - ASCII 'v'
jne r_filename
movl    $4,%eax        # write(
movl    $1,%ebx        #   STDOUT,
movl    $Leng, %edx     #   len *
movl    $Inform, %ecx #   *Buffer
int     $0x80          # );    

如何使用AWK格式化这样的注释：

cmpb $45, (%ebx)        # 45 - ASCII '-'
jne r_filename
cmpb $118, 1(%ebx)      # 118 - ASCII 'v'
jne r_filename
movl    $4,%eax         # write(
movl    $1,%ebx         #   STDOUT,
movl    $Leng, %edx     #   len *
movl    $Inform, %ecx   #   *Buffer
int     $0x80           # );  

解决方法:

Perl的答案也可以接受吗？

script.pl：

#!/usr/bin/perl -w

while(<>) {
        if(m/^(.+?)\s*(#.*)?$/) {
                my ($code, $comment) = ($1, $2);

                if($comment) {
                        printf "%- 40s %s\n", $code, $comment;
                }
                else {
                        print "$code\n";
                }
        }
        else {
                print;
        }
}

叫它：

cat file.asm | perl script.pl
