From ab38a727c990476872ac4995792fc0d38d922d7f Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Sat, 24 Apr 2010 13:12:56 +0000 Subject: * defs.h: Adjust comment. * filesystem.h, filesystem.c: New files. * Makefile.in (SFILES): Add filesystem.c. (COMMON_OBS): Add filesystem.o. * solib.c (solib_find): Handle DOS-based filesystems. Handle different target and host path flavours. * arm-symbian-tdep.c (arm_symbian_init_abi): Set has_dos_based_file_system on the gdbarch. * arm-wince-tdep.c (arm_wince_init_abi): Ditto. * i386-cygwin-tdep.c (i386_cygwin_init_abi): Ditto. * i386-tdep.c (i386_go32_init_abi): Ditto. * gdbarch.sh (has_dos_based_file_system): New. * gdbarch.h, gdbarch.c: Regenerate. * NEWS: Mention improved support for remote targets with DOS-based filesystems. Mention new `set/show target-file-system-kind' commands. gdb/doc/ * gdb.texinfo (Commands to specify files): Describe what how GDB looks up DOS-based filesystem paths on the system root. Document the new `set/show target-file-system-kind' commands. --- gdb/filesystem.c | 103 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 103 insertions(+) create mode 100644 gdb/filesystem.c (limited to 'gdb/filesystem.c') diff --git a/gdb/filesystem.c b/gdb/filesystem.c new file mode 100644 index 0000000..38a597d --- /dev/null +++ b/gdb/filesystem.c @@ -0,0 +1,103 @@ +/* Handle different target file systems for GDB, the GNU Debugger. + + Copyright (C) 2010 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 3 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.
