是否所有版本的GCC支持gcc的@file选项？ [英] Do all gcc versions support gcc's @file option?

问题描述

据我记得一些旧版本的GCC不支持@file选项。我不是很肯定。可能有人给与此相关的任何指针？

As far as I remember some older gcc versions don't support the @file option. I am not very sure. Could someone give any pointers related to this?

   @file
   Read command-line options from file.  The options read are inserted
   in place of the original @file option.  If file does not exist, or
   cannot be read, then the option will be treated literally, and not
   removed.

   Options in file are separated by whitespace.  A whitespace
   character may be included in an option by surrounding the entire
   option in either single or double quotes.  Any character (including
   a backslash) may be included by prefixing the character to be
   included with a backslash.  The file may itself contain additional
   @file options; any such options will be processed recursively.

推荐答案

这是致力于GCC源位置：

This was committed to gcc source here:

2005-11-23  Mark Mitchell  <[e-mail]>

    * doc/invoke.texi: For man pages, include gcc-vers.texi.
    List @file in the option summary.  Include the libiberty
    documentation for @file.
    * gcc.c (main): Call expandargv.
    * Makefile.in (gcc-vers.texi): Define srcdir.

据发布记录，这应该已经使它成为GCC 4.1

According to release history, this should have made it into GCC 4.1
