This commit effectively changes the default location of the .gdbinit file, while maintaining backward compatibility. For non Apple hosts the .gdbinit file will now be looked for in the following locations: $XDG_CONFIG_HOME/gdb/gdbinit $HOME/.config/gdb/gdbinit $HOME/.gdbinit On Apple hosts the search order is instead: $HOME/Library/Preferences/gdb/gdbinit $HOME/.gdbinit I've performed an extensive rewrite of the documentation, moving all information about initialization files and where to find them into a new @node, text from other areas has been moved into this one location, and other areas cross-reference to this new @node as much as possible. gdb/ChangeLog: * NEWS: Mention changes to config file search path. * main.c gdb/doc/ChangeLog: * gdb.texinfo (Mode Options): Descriptions of initialization files has been moved to 'Initialization Files'. (Startup): Likewise. (Initialization Files): New node. (gdb man): Update to mention alternative file paths. (gdbinit man): Likewise.
