	* dwarfread.c (dbsize):  New variable to hold size of dwarf info.
	* dwarfread.c (dwarf_build_psymtabs):  Rename dbsize parameter to 
	dbfsize and use it to initialize new local file scope dbsize.

	  other nat file exists for this configuration.
	* sparc-tdep.c: no longer include sys/ptrace.h.

	* breakpoint.c, exec.c, language.c, main.c, printcmd.c, symfile.c,
	target.c, valprint.c:  Use unfiltered forms of f/printf, et. al.
	until we can figure out a better way to do paging.

Sat Sep 26 02:07:31 1992  John Gilmore  ([e-mail])

Fri Sep 25 21:59:27 1992  John Gilmore  ([e-mail])

	Split non-target-dependent code out of target_attach routines.

	* target.h:  Comments on target_attach args and results.
	* infcmd.c (attach_command): Check for existing execution, call

	* tm-sparc.h, dbxread.c (read_ofile_symtab):  Install Jim Wilson's
	fix to differentiate between gcc1 & gcc2 compiled files so that we
	can debug calls that pass structs as args correctly.
	* symmisc.c (dump_symtab):  If block was compiled with gcc, say
	so, and what version.

	* remote.c (remote_wait):  Make regs be char to avoid picayune
	ANSI compiler warnings.

	  get_core_registers, core_files_info, core_ops): moved to corelow.c
	  (_initialize_core): removed addition of core_ops target.

Wed Sep 23 11:14:53 1992  Stu Grossman  (grossman at cygnus.com)

	* m68k-tdep.c (m68k_saved_pc_after_call):  Use 'GDB_TARGET_IS_SUN3'
	instead of 'sun' predefined symbol so that trap analysis code is
	enabled only when the TARGET is a sun3.

Tue Sep 22 17:13:19 1992  Ken Raeburn  ([e-mail])

	* tm-i960.h (ext_format_i960): Add top-level declaration.

	(Jonathan Stone).

	process will be the default target.

	* target.c (find_default_run_target, find_default_attach,
	find_default_create_inferior, return_zero):  new functions.
	(cleanup_target):  Make return_zero the default for to_can_run.

	* exec.c (exec_ops), core.c (core_ops):  Replace child_attach and
	child_create_inferior references with find_default_XXX instead.

	struct target_ops initializations throughout GDB, except: 
	* inftarg.c (child_ops): Use new child_can_run() to enable child runs.

	* infrun.c (child_create_inferior):  Clean up error handling when
	no exec file is specified.
	(child_attach):  Don't require exec file.

Mon Sep 21 19:43:13 1992  John Gilmore and K. Richard Pixley ([e-mail])

	Remove kill_inferior_fast, in favor of target_kill, which goes
	through the target vector.

	* inferior.h (kill_inferior_fast): remove declaration.

	* main.c (disconnect): call quit_cover using catch_errors rather
	than calling kill_inferior_fast directly.  New way goes through
	the target vector, handles attached processes, and writes
	command history if appropriate.
	(quit_cover): new function, wrapper for quit_command.

	* convex-xdep.c, go32-xdep.c, hppabsd-xdep.c, hppahpux-xdep.c,

	operands to memory management instructions, from WRS.

	* main.c (main):  Back out previous language setting changes.
	Replace with simple default to C before processing any init
	files.  There MUST be a language set, even in the absence of
	init files or executables, or expression parsing fails.

Sat Sep 19 09:52:26 1992  Fred Fish  ([e-mail])

	* main.c (main):  Move code that sets initial language to
	symfile.c.  Fixup places where command files are processed to
	be consistent in setting a default language if none has been
	previously set.
	* symfile.c (set_initial_language):  Add code moved from
	main() that sets an initial default language when a new
	symbol file is read.
