[PATCH] Fix default target selection arguments for "exec" targets

[Keith Seitz <keiths@redhat.com>]

[-- Attachment #1: Type: text/plain, Size: 1014 bytes --]

Hi,

I've committed the attached patch which fixes the two issues reported 
recently regarding 1) the exec target not being selected by default on 
non-cross versions of insight and 2) arguments not being synced between 
the console and the dialog.

I did not check this on cross debuggers, but I don't think I touched 
anything that would affect those. But as always, if you find that I 
broke something, let me know and I will put it on my TODO list.

I will do a snapshot of insight on Monday to reflect the updated code base.

Keith

ChangeLog
2009-04-23  Keith Seitz  <keiths@redhat.com>

	* library/targetselection.itb (init_target_db): Add comment
	about "arguments" vs "options" on native debuggers.
	(build_win): If the target is "default", choose "Exec" for native
	debuggers. For cross debuggers, let the user choose.
	(write_saved): For exec targets, save target options to gdb via
	gdb_set_inferior_args.
	(config_dialog): For "exec" targets, save gdb's stored arguments
	into the options preference.
