Move struct lwp_info def to linux-nat.h. * linux-proc.c: Include linux-nat.h. (linux_make_note_section): Iterate over lwps instead of threads. (linux_do_thread_registers): Use lwp instead of merged pid. * config/nm-linux.h: Move miscelaneous def'ns to linux-nat.h. * Makefile.in (lin-lwp.o, linux-proc.o, linux-nat.o): Add dependency on linux_nat_h. --- gdb/linux-nat.h | 70 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 70 insertions(+) create mode 100644 gdb/linux-nat.h (limited to 'gdb/linux-nat.h') diff --git a/gdb/linux-nat.h b/gdb/linux-nat.h new file mode 100644 index 0000000..78312d7 --- /dev/null +++ b/gdb/linux-nat.h @@ -0,0 +1,70 @@ +/* Native debugging support for GNU/Linux (LWP layer). + Copyright 2000, 2001, 2002, 2003 Free Software Foundation, Inc. + + This file is part of GDB. + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
