+	(vprintf): Define to call _doprnt.
+
+Tue Jul 26 03:05:28 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
+
+	* symmisc.c: (print_symtabs)  Check the status of the fopen and
+	call perror_with_name if needed.
+
+Sat Jul 23 00:14:20 1988  Peter TerMaat  (pete at corn-chex.ai.mit.edu)
+
+	* printcmd.c: (delete_display) Check for existence of display
+	chain before deleting anything.
+
+Thu Jul  7 08:47:03 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)
+
+	* main.c: New vars win_argv, win_argc, win_prgm to talk to xgdb.

+
+	* dbxread.c: (define_symbol) store static functions ('f') in the

+	type X' rather than as `X'.
+
+Mon Jul  4 17:07:31 1988  Pete TerMaat  (pete at frosted-flakes.ai.mit.edu)
+
+	* dbxread.c: (read_dbx_symtab) Avoid reading symbol tables of
+	libraries by checking for symbols which begin with "-l" (in

+
+Mon Jun 27 23:27:51 1988  Pete TerMaat  (pete at frosted-flakes.ai.mit.edu)
+
+	* dbxread.c: (define_symbol) and coffread.c: (process_coff_symbol)

+
+	* findvar.c: (locate_var_value, read_var_value) got rid of checks
+	for LOC_BLOCK which called `lookup_function_type'.  These checks
+	are no longer needed because of the change to dbxread.c.
+
+	* infcmd.c: (finish_command) Now uses target_type instead of type
+	for functions, in keeping with the change to dbxread.c.
+
+Sat Jun 25 00:24:09 1988  Pete TerMaat  (pete at corn-chex.ai.mit.edu)
+
+	* infrun.c: (normal_stop) Added a check for permissions on the
+	exec file before printing the "You have encountered a bug in sh"
+	message.  Apparently on some systems an attempt by the shell to
+	exec an	unexecutable file had resulted in the "You have 
+	encountered" message.
+
+Wed Jun 22 00:00:02 1988  Pete TerMaat  (pete at corn-chex.ai.mit.edu)
+

+
+Fri Jun 17 21:24:48 1988  Pete TerMaat  (pete at lucky-charms.ai.mit.edu)

+	* m-umax.h: (FIX_CALL_DUMMY): fixed typo (the last `flipped' was
+	`fliped')
+
+	* m-pn.h, m-npl.h: added #define gould, since this is needed in
+	core.c.
+
+Tue Jun 14 04:07:50 1988  Pete TerMaat  (pete at lucky-charms.ai.mit.edu)
+
+	* Removed unused variables from m-pn.h, m-npl.h in

+
+Mon May 23 14:54:54 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
+
+	* source.c (print_source_lines): New arg NOERROR nonzero means
+	if file is not found just print message and return (don't throw).

+
+	* source.c (identify_source_line): Set defaults for `list' command.

+
+Fri Apr 15 01:01:40 1988  Chris Hanson  (cph at kleph)
+
+	* inflow.c [! TIOCGPGRP]: Do not call `setpgrp' for inferior.
+	Instead, disable SIGINT and SIGQUIT while the inferior is running.
+	Unfortunately this means that C-c typed while GDB is running will
+	cause the inferior to receive SIGINT when it is resumed.
+	* utils.c (quit) [! TIOCGPGRP]: Cause quit message to remind user
+	that the inferior will see SIGINT.
+

+	* stack.c (print_frame_info): Pass that argument.
+
+	* main.c (cd_command): Convert any relative pathname to absolute.
+	Simplify if `.' or `..' appear.

+	running a stack dummy.
+
+	* inflow.c (term_status_command) [HAVE_TERMIO]: Show all available
+	terminal status information.
+
+Tue Apr 12 19:11:00 1988  Chris Hanson  (cph at kleph)
+
+	* stack.c (print_frame_info): When -fullname is given and
+	`identify_source_line' succeeds, do not print real pc even if it
+	differs from the start pc for the source line.  This information
+	is not very useful and tends to screw up gdb-mode in emacs.
+
+Mon Apr 11 14:22:10 1988  Chris Hanson  (cph at kleph)
+
+	* dbxread.c (define_symbol): Don't forget to terminate

+	TRAP #1 not TRAP #15.
+

+
+	* dbxread.c (symbol_file_command): Check stringtab size by doing `stat'

+
+Fri Apr  8 16:39:11 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)
+
+	* Makefile: Delete `-lg' entirely; not needed now that linking is done
+	with $(CC).
+
+Fri Apr  8 13:41:46 1988  Chris Hanson  (cph at kleph)
+
+	* m68k-opcode.h: Fix operand-string of fmovel insns.
+
+	* Makefile: Put "-lg" in CLIBS because there is no such library in
+	HPUX.  Update the comment for HPUX.
+

+
+	* findvar.c (locate_var_value): For &FCN, do lookup_function_type.

+	* utils.c (quit): Need HAVE_TERMIO conditional.  Also include param.h.
+
+	* inflow.c: If HAVE_TERMIO, use termio and fake it to look like stty.

+	Use of tchars, ltchars, pgrp conditional on existence of the
+	ioctls that handle them.
+	(terminal_init_inferior, terminal_inferior, terminal_ours,
+	 term_status_command, initialize):
+	Conditionals for HAVE_TERMIO and existence of various ioctls.
+	({fetch,store}_inferior_registers): Separate versions for HP9K320.
+
+	* m68k-pinsn.c (convert_{to,from}_68881): Alternate asms for HPUX_ASM.

+
+	* dbxread.c (add_symbol_to_list, finish_block, read_enum_type):
+	Symbol-lists now hold up to 20 symbols in each `struct pending'

+	(symbol_file_command): These macros replace open code.
+
+	* values.c (unpack_double): When fetching `double' from memory,
+	make it double-aligned, since some machines need that.

+
+Thu Jan 22 00:31:03 1987  Richard M. Stallman  (rms at prep)
+
+	* Version 2.0.
+
+	* blockframe.c (get_pc_function_start):
+	Understand misc functions.
+
+	* core.c (core_file_command):
+	Copy all register contents into the array `registers'
+	Save a.out header of executable file in core_aouthdr.
+	Print name of executable file that was running, if we know
+	where to find it.
+
+	* core.c (exec_file_command):
+	Save a.out header in exec_aouthdr and file's mtime
+	in exec_mtime.
+
+	* core.c (validate_files): Check that core file's a.out hdr
+	matches exec file's.
+
+	* New handling of registers:
+	Now all registers are fetched once when the program stops or
+	when a core file is selected.  Their contents are kept in
+	`registers', an array of bytes.  This is done by
+	`fetch_inferior_registers'.  `read_register', etc., just look
+	there.  Writing a register works through
+	`store_inferior_registers' which writes one or all registers
+	from `registers' back to the inferior.
+
+	A register now can have a "raw" data format and a "virtual"
+	data format, which may require conversion or even be different sizes.
+	The conversion can be different for different registers.
+	For example, the 68000 cpu registers need no conversion
+	and both raw and virtual size is 4, but the 68881 floating point
+	registers have raw size 12 (for extended fmt) and virtual size 8
+	(for double).  Macros in the m- file such as REGISTER_BYTES,
+	REGISTER_BYTE, REGISTER_{RAW,VIRTUAL}_SIZE, and
+	REGISTER_CONVERT_TO_{RAW,VIRTUAL} control these things.
+
+	`read_register' and `write_register' are usable only on registers
+	which hold an int and need no conversion (raw fmt = virtual fmt).
+	For other registers, `read_register_bytes' is used, or
+	`read_relative_register_raw_bytes'.
+
+	* m-sun3.h: Define the 68881 fp registers.
+	Know how to recognize insns that save them.
+	Make dummy frames save them.
+
+	* core.c (read_register, write_registers): Functions deleted.
+	* findvar.c (read_register, write_registers): New functions,
+	not the same as the old ones of the same name.
+
+	* findvar.c (supply_register): Function used by
+	fetch_inferior_registers, etc., to install the register
+	values fetched from the inferior.
+
+	* findvar.c (read_register_bytes, write_register_bytes):
+	Read spec'd number of bytes from the byte-array `registers'.
+
+	* findvar.c (read_relative_register_raw_bytes):
+	Replaces old function `read_relative_register'; accepts
+	address of where to store the contents; # bytes stored is size
+	of the specified register in raw format.
+
+	* findvar.c (value_of_register, read_var_value):
+	Convert register values and values of register variables
+	from raw format to virtual format.
+
+	* findvar.c (locate_var_value): Like `read_var_value' but
+	returns value for variable's address.
+
+	* value.h: Add new field VALUE_REGNO to each value.  It holds
+	register number to control virtual-to-raw conversion
+	for assignments to the value.
+
+	* valops.c (value_assign): Convert data from virtual to raw format
+	if value came from a register variable.
+	Use read_register_bytes and write_register_bytes.
+
+
+	* infcmd.c (continue_command): Subtract 1 from arg
+	before setting breakpoint's ignore-count.
+
+	* infcmd.c (jump_command): Query if spec'd line is outside
+	of the current function.
+
+	* infcmd.c (finish_command): Now finish the selected frame,
+	and no arg required.
+
+	* infcmd.c (set_environment_command): Allow space to separate
+	varname and value.
+
+	* infcmd.c (registers_info): Print both raw and virtual data
+	format if they differ.  Allow register name as arg.
+	Ask for a Newline each 16 registers.
+
+	* inflow.c (kill_inferior): call mark_breakpoints_out.
+	* inflow.c ({fetch,store}_inferior_registers for Sun):
+	Get the fp registers and store them in right places in
+	`registers'.
+	* inflow.c ({read,write}_inferior_register): Deleted.
+
+	* infrun.c (wait_for_inferior): Single-stepping is not considered
+	to have hit a breakpoint unless the pc before the step matches the
+	address of the breakpoint.  Necessary on machines where
+	breakpoints leave the pc incremented.
+
+	If shell gets SIGSEGV, pass the signal silently to it.
+
+	* m68k-pinsn.c, m68k-opcode.h:
+	Add the 68881 instructions.  New operand codes `F', `I', `s'
+	and `k' are needed for them.  New place codes `78tcik'.
+	NEXTBYTE now skips a word but fetches just a byte.
+	Explicit sign-extension removed from NEXTBYTE and NEXTWORD.
+	NEXTSINGLE, NEXTDOUBLE, NEXTEXTEND and NEXTPACKED defined.
+	Various changes to implement the new operand and place codes.
+	print_index changed because displacement-size codes for
+	word and long displacement were interchanged.

+
+	* source.c (openp): Simplify `./' in specified name.
+
+	* source.c (find_source_lines): Compare source mtime against
+	`exec_mtime' and warn if source is newer.
+
+	* source.c (line_info): No arg means use last line listed
+	or line following last one this command was used on.
+	If from tty, clear out argument so Return is like `i li' without
+	arg.
+
+	* stack.c (frame_info): Print addresses registers are saved at.
+
+	* stack.c (return_command): When asking for confirmation, give
+	name of function that will be made to return.
+
+	* valops.c (call_function): If function type is
+	pointer-to-function, dereference it to compute return type.
+	If pointer-to-object, assume function returns int.
+	If char, assume that the value's address is the function address
+	(because it's a misc functon).  If int, the value itself is the
+	function address.
+
+	* dbxread.c (compare_symbols): Sort register symbols
+	before all others.
+
+	* eval.c (evaluate_subexp_for_address): New function like
+	`evaluate_subexp' but returns a value for the address where
+	the subexpression's value would be located.
+
+	* eval.c (evaluate_subexp_for_sizeof): New function like
+	`evaluate_subexp' but returns a value for the size of the subexp.
+
+	* eval.c (evaluate_subexp_with_coercion): Like `evaluate_subexp'
+	but coerces arrays to pointers (without taking the time to
+	read the array contents).
+
+	* eval.c (evaluate_subexp): Use the three new functions above
+	when appropriate instead of calling self recursively.
+

+	If from_tty, mention any other breakpoints set at same location.
+
+	* symtab.c (decode_line_1):

+
+	* version.c: version 1.10.
+
+	* valprint.c (type_print*):
+	SHOW < 0 now means abbreviate struct/union members

+	Doc for `print' command changed for this.
+

+	Free and zero out any line_charpos's saved in source symtabs.
+
+	* breakpoint.c (condition_command):
+	Parse the condition in the environment of the code where the

+	or allocates a new, empty type for those typenums and returns it.
+
+	* symtab.c (smash_type_to_{pointer,function}):
+	New functions modify an already-allocated type object
+	to be a pointer to or function returning some given type.
+
+	* dbxread.c (read_type): Uses dbx_alloc_type in many cases.
+	Reading a pointer or function type now works by doing that,
+	then reading the value type or type pointed to, then smashing
+	it into the type already allocated.  This makes some fwd refs win.
+	Likewise for structs and unions.
+
+	* dbxread.c (read_struct_type): Now receives the type object
+	as args.  Used to get typenums as args and look up the type
+	itself.

+Sun Nov 16 14:59:07 1986  Richard M. Stallman  (rms at prep)
+
+	* values.c (value_field): Was adding in byte offset
+	before calling unpack_field_as_long, which itself
+	adds in the offset.  Now pass addr of start of structure.
+
+	* infrun.c (normal_stop): Clean up inferior_pid conditionals:
+	just return early if no inferior.
+
+Thu Nov 13 15:45:50 1986  Richard M. Stallman  (rms at prep)

+
+	* dbxread.c (add_{new,old}_header_file):
+	Accept an instance code as arg and treat it as if it were
+	part of the file name for distinguishing and finding entries.
+
+	* dbxread.c (add_new_header_file, read_type):
+	Turn off the header_file_prev_index feature with #if 0.
+
+	* values.c (unpack_field_as_long, modify_field):

+
+	* infrun.c (start_inferior, wait_for_inferior):
+	Eliminate `stop_in_shell' which was not being maintained right.
+	New variable `running_in_shell' is set to 1 or 0 when the
+	expected SIGTRAPs happen, and is simply examined at other times.
+
+	* infrun.c (wait_for_inferior):
+	If get SIGSEGV with running_in_shell == 1, it is sh
+	allocating memory.  Pass the signal silently to the shell.
+
+	* core.c (exec_file_command):
+	data_{start,end} are adjusted unconditionally when an
+	exec file is opened, so closing counter-adjustment is
+	now unconditional as well.
+
+	* printcmd.c (x_command):
+	Don't erase the expression from the calling args
+	if cllaed noninteractively (used to be clobbering
+	definitions of user-defined commands).
