commit 3d548a532dd74f9bf5f2033541f0b504d96baf04
Author: Tom Tromey <tromey@redhat.com>
Date:   Mon Dec 30 20:34:16 2013 -0700

    move the "main" data into the per-BFD object
    
    This adds the "main"-related data into the per-BFD.  This is needed
    because once symbol sharing across objfiles is complete, computing the
    main name as a side effect of symbol reading will no longer work --
    the symbols simply won't be re-read.
    
    After this change, set_main_name is only used by the main_name
    machinery itself, so this patch makes it static.

    move main name into the progspace
    
    This moves the "main" name and language into an object attached to the
    current progspace.  This prevents problems if there are multiple
    inferiors tha have different ideas of "main" -- which matters at least
    for unwinding, see frame.c:inside_main_func.
    
    2014-01-15  Tom Tromey  <tromey@redhat.com>
    
    	* symtab.c (main_progspace_key): New global.
    	(struct main_info): New.
    	(name_of_main, language_of_main): Remove.
    	(get_main_info, main_info_cleanup): New function.
    	(set_main_name, main_name, main_language): Use get_main_info.
    	(_initialize_symtab): Initialize main_progspace_key.

    make language_of_main static
    
    This makes the global language_of_main static.  Now it can be set only
    via a new argument to set_main_name.
