Reads in a header in a .debug_line section. (display_debug_lines_raw): Use new function. Handle fragmentary .debug_line sections. (display_debug_lines_decoded): Likewise. * readelf.c (process_section_headers): Handle fragmenatry .debug_line sections. (display_debug_section): Likewise. * as.c (Options): Add -gdwarf-sections. (parse_args): Likewise. * as.h (flag_dwarf_sections): Declare. * dwarf2dbg.c (emit_fixed_inc_line_addr): Skip section changes. (process_entries): When -gdwarf-sections is enabled generate fragmentary .debug_line sections. (out_debug_line): Set the section for the .debug_line section end symbol. * doc/as.texinfo: Document -gdwarf-sections. * NEWS: Mention -gdwarf-sections. * gas/elf/dwarf2-3.d: Fix expected readelf output. * scripttempl/DWARF.sc: Add support for .debug_line.* and .debug_line_end. --- gas/doc/as.texinfo | 24 ++++++++++++++---------- 1 file changed, 14 insertions(+), 10 deletions(-) (limited to 'gas/doc') diff --git a/gas/doc/as.texinfo b/gas/doc/as.texinfo index 1476c14676..9c55ef4e4b 100644 --- a/gas/doc/as.texinfo +++ b/gas/doc/as.texinfo @@ -1,7 +1,5 @@ \input texinfo @c -*-Texinfo-*- -@c Copyright 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, -@c 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012 -@c Free Software Foundation, Inc. +@c Copyright 1991-2013 Free Software Foundation, Inc. @c UPDATE!!
