[binutils-gdb] mi/mi-cmd-stack.c|frame filters: print_values <-> ext_lang_frame_args


https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=10367c7c946a123597cbc5efaa44c18912e5e43a

commit 10367c7c946a123597cbc5efaa44c18912e5e43a
Author: Pedro Alves <palves@redhat.com>
Date:   Wed Oct 22 05:09:07 2014 +0100

    mi/mi-cmd-stack.c|frame filters: print_values <-> ext_lang_frame_args
    
    The enums are value compatible by design, but building in C++ mode trips
    on them, like:
    
      ...
      gdb/mi/mi-cmd-stack.c:363:34: error: cannot convert â??print_valuesâ?? to â??ext_lang_frame_argsâ?? for argument â??3â?? to â??ext_lang_bt_status apply_ext_lang_frame_filter(frame_info*, int, ext_lang_frame_args, ui_out*, int, int)â??
      ...
    
    Fix this by adding a helper function.
    
    gdb/ChangeLog:
    2015-02-27  Pedro Alves  <palves@redhat.com>
    
    	* mi/mi-cmd-stack.c (mi_apply_ext_lang_frame_filter): New
    	function.
    	(mi_cmd_stack_list_locals, mi_cmd_stack_list_args)
    	(mi_cmd_stack_list_variables): Use it.
