Fri Dec 18 10:24:14 1987 Richard Stallman (rms at frosted-flakes)
* findvar.c (read_var_value): Share code between values really
in registers and values in saved registers.
Register short on a big-endian machine needs a VALUE_OFFSET.

saved register variable that's shorter than the register.
Thu Dec 17 08:26:31 1987 Richard Stallman (rms at lucky-charms)

Sat Dec 12 04:36:39 1987 Richard Stallman (rms at corn-chex)
* dbxread.c (end_symtab): The free_code for a symseg got
from a file should be free_linetable.
* dbxread.c: Allocate blockvector, blocks, symbols and symbol names
from the symbol-obstack, and use free_linetable for all files.
The typevector is still malloc'd, so put it in the free_ptr

* 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.

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.
* m68k-pinsn.c (convert_{from,to}_68881): Functions added
to support REGISTER_CONVERT_TO_{RAW,VIRTUAL} on 68000.
* main.c (main): Move around calls to setjmp.
* main.c (define_command, document_command):

`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 (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

`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 or cleared more than one breakpoint at location,
print which bpts were deleted.
* breakpoint.c (break_command_1, break_command, tbreak_command):
If from_tty, mention any other breakpoints set at same location.
* symtab.c (decode_line_1):
If no symtabs, err mentioning `symbol-file' command rather than
saying "function foo not defined"

* m-sun[23].h (PUSH_DUMMY_FRAME): Push the old PS register.
* m-sun[23].h (CALL_DUMMY, etc.): Fix erroneous binary code for
the addl #nnn,sp instruction. Insert clrw -(sp); movw -(sp)
to indicate that the PS has been saved.

mark_breakpoints_out so it works to delete breakpoints afterward.
* infrun.c (normal_stop): After popping a stack dummy frame,
select the frame that we get to.
* dbxread.c (process_one_symbol): Store new `depth' field
in all context_stack elements created. For N_RBRAC, test

start "Invalid symbol data: " and end with value of symnum.
Also change a few aborts to errors.
Mon Dec 1 20:20:37 1986 Richard M. Stallman (rms at prep)
* version.c: Version 1.11.
* breakpoint.c (condition_command): If no condition spec'd,
print "breakpoint N now unconditional".
* breakpoint.c (commands_command): Give different error messages
for cases of args not containing a breakpoint number
and args containing anything after the breakpoint number.
* commands.c (lookup_command): Don't store a zero in *p

what the effect is.
* dbxread.c (define_symbol): Accept class code 'v'
for static variable within a function.
* dbxread.c (read_type): Now allow any plain number or

define new type same as type with specified number, or define
it as void if specified number's type is not yet mentioned.
* m68k-pinsn.c (print_insn_arg): Case of general operand
in byte insn that happened to be immediate used wrong arg-size.
* printcmd.c (set_next_address): Set next_address from arg

what new value it wants use for the path.
* source.c (list_command): Don't die in cases like `list ,+30'.
* source.c (line_info): Call `set_next_address' to make `x'
display the text of the line. Change `info list' doc string.
Sat Nov 29 07:59:29 1986 Richard M. Stallman (rms at prep)
* printcmd.c (undisplay_command): If get no arg,
rather than crashing, query and then delete undisplay everything.
Fri Nov 28 15:43:52 1986 Richard M. Stallman (rms at prep)
* dbxread.c (process_one_symbol): If N_LBRAC sym
has a greater value that N_RBRAC, ignore the
N_LBRAC value and give the block zero length.
Tue Nov 25 03:10:12 1986 Richard M. Stallman (rms at prep)
* dbxread.c (process_one_symbol): Ignore N_NSYMS symbols
that appear in Ultrix.
Sat Nov 22 22:49:06 1986 Richard M. Stallman (rms at prep)
* version.c: version 1.10.
* valprint.c (type_print*):
SHOW < 0 now means abbreviate struct/union members
or enum values with `...'. SHOW now decremented on
each recursion in type_print_base. Several places
that used to check !show now check show <= 0.
* valprint.c (val_print): Pass -1 for SHOW to type_print
when printing typename inside parens or braces.
* printcmd.c (print_command): If no value specified to print,
print the value of $.

OP_MEMVAL renamed UNOP_MEMVAL
and now allows any expression, not just an integer address.
It now has same format as UNOP_CAST and works almost like it.
Each place that referred to it has been rewritten
starting with a copy of the code that handles UNOP_CAST.
Doc for `print' command changed for this.
* source.c (init_source_path):
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
breakpoint is set. This requires finding the breakpoint
before parsing, so code is rearranged.
* dbxread.c (dbx_alloc_type):
New function given typenums returns the type for those typenums
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.
* dbxread.c (symbol_file_command):
At very end, clear out any type name that `char *' has received.
Thu Nov 20 16:43:53 1986 Richard M. Stallman (rms at prep)

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 (struct header_file): add new field .instance
to distinguish the various entries for one header file.
* dbxread.c (process_one_symbol): Use the `value' of
a N_BINCL or N_EXCL as the instance code for the header file.
* 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):
Run-time test to distinguish big and little endian machines
and do shifting accordingly.

* breakpoint.c (delete_command):
Ask for confirmation when used with no arg (delete all).
Fri Nov 7 11:23:09 1986 Richard M. Stallman (rms at prep)
* 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).
* source.c (list_command): likewise.
Wed Nov 5 09:41:00 1986 Richard M. Stallman (rms at prep)
* Makefile: New variable OBSTACK1 that people can use
to make obstack.o a dependency of gdb.
* breakpoint.c (initialize):
Define new aliases "br", "bre" and "brea" for "break".
