What has changed in GDB?
|
||||
(Organized release by release)
|
||||
|
||||
*** Changes in GDB-4.15:
|
||||
|
||||
* Remote targets use caching
|
||||
|
||||
Remote targets now use a data cache to speed up communication with the
|
||||
remote side.
|
||||
The data cache could lead to incorrect results because it doesn't know
|
||||
about volatile variables, thus making it impossible to debug targets
|
||||
which use memory mapped I/O devices. `set remotecache off' turns the
|
||||
the data cache off.
|
||||
*** Changes since GDB-4.15:
|
||||
|
||||
* New native configurations

*** Changes in GDB-4.15:
|
||||
|
||||
* Psymtabs for XCOFF
|
||||
|
||||
The symbol reader for AIX GDB now uses partial symbol tables. This
|
||||
can greatly improve startup time, especially for large executables.
|
||||
|
||||
* Remote targets use caching
|
||||
|
||||
Remote targets now use a data cache to speed up communication with the
|
||||
remote side. The data cache could lead to incorrect results because
|
||||
it doesn't know about volatile variables, thus making it impossible to
|
||||
debug targets which use memory mapped I/O devices. `set remotecache
|
||||
off' turns the the data cache off.
|
||||
|
||||
* Remote targets may have threads
|
||||
|
||||
The standard remote protocol now includes support for multiple threads
|
||||
in the target system, using new protocol commands 'H' and 'T'. See
|
||||
gdb/remote.c for details.
|
||||
|
||||
* NetROM support
|
||||
|
||||
If GDB is configured with `--enable-netrom', then it will include
|
||||
support for the NetROM ROM emulator from XLNT Designs. The NetROM
|
||||
acts as though it is a bank of ROM on the target board, but you can
|
||||
write into it over the network. GDB's support consists only of
|
||||
support for fast loading into the emulated ROM; to debug, you must use
|
||||
another protocol, such as standard remote protocol. The usual
|
||||
sequence is something like
|
||||
|
||||
target nrom <netrom-hostname>
|
||||
load <prog>
|
||||
target remote <netrom-hostname>:1235
|
||||
|
||||
* Macintosh host
|
||||
|
||||
GDB now includes support for the Apple Macintosh, as a host only. It
|
||||
may be run as either an MPW tool or as a standalone application, and
|
||||
it can debug through the serial port. All the usual GDB commands are
|
||||
available, but to the target command, you must supply "serial" as the
|
||||
device type instead of "/dev/ttyXX". See mpw-README in the main
|
||||
directory for more information on how to build. The MPW configuration
|
||||
scripts */mpw-config.in support only a few targets, and only the
|
||||
mips-idt-ecoff target has been tested.
|
||||
|
||||
* Autoconf
|
||||
|
||||
GDB configuration now uses autoconf. This is not user-visible,
|
||||
but does simplify configuration and building.
|
||||
|
||||
* hpux10
|
||||
|
||||
Get now supports hpux10.
|
||||
|
||||

|
||||
|
||||
* New native configurations

|

|
||||
Known Bugs
|
||||
==========
|
||||
|
||||
generic problems
|
||||
|
||||
o If you open an Assembly window before you have run the program, gdbtk
|
||||
pops up a dialog box titled "Error in Tcl Script" with the contents
|
||||
"Error: No function contains the specified address". Trying to then
|
||||
do other things brings up a dialog box with the contents "Error:
|
||||
can't read 'current_asm_label': no such variable.
|
||||
|
||||
Solution: Close Assembly window when there is no program running.
|
||||
|
||||
o If you open Registers window before you have run the program, gdbtk
|
||||
pops up a dialog box titled "Error in Tcl Script" with the contents
|
||||
"Error: No registers". Trying to then do other things, like use the
|
||||
Start button to run the program, repeatedly produce the same dialog
|
||||
box and the action is not performed.
|
||||
|
||||
Solution: Close Registers window when there is no program running.
|
||||
|
||||
o Expressions are sometimes not displayed correctly in the Expression
|
||||
window. I.E. "argc" works, as does "*(argv+argc)" but not "argv[argc]".
|
||||
|
||||
Solution: None
|
||||
|
||||
o The Breakpoint window does not get automatically updated and changes
|
||||
made in the window are not reflected back in the results from "info br".
|
||||
I.E. the breakpoint count in the window is not updated at each hit and
|
||||
enabling/disabling the breakpoint from the Breakpoint window has no effect.
|
||||
|
||||
Solution: Use the command interface to control breakpoints and don't
|
||||
open a Breakpoint window.
|
||||
|
||||
o Sometimes while an expression window is active you get a dialog box
|
||||
that complains "Error: invalide command name ".expr.e5.expr" for
|
||||
example. The Tcl stack trace looks something like:
|
||||
|
||||
invalid command name ".expr.e5.expr"
|
||||
while executing
|
||||
"$e.expr get 0.0 end"
|
||||
invoked from within
|
||||
"set expr [$e.expr get 0.0 end]..."
|
||||
(procedure "update_expr" line 17)
|
||||
invoked from within
|
||||
"update_expr $expr_num"
|
||||
invoked from within
|
||||
"if $expr_update_list($expr_num) {
|
||||
update_expr $expr_num
|
||||
.
|
||||
.
|
||||
.
|
||||
|
||||
Solution: None except close expression window and reopen it.
|
||||
|
||||
o If you select the "Down" button in either the Source or Assembly
|
||||
window while in the bottom (innermost) frame, the error message that
|
||||
results goes just to the command window and may be missed if the
|
||||
command window is not open. This may also apply to other messages
|
||||
as well. It should probably put up a notification box instead.
|
||||
|
||||
Solution: Keep Command window open to see error messages.
|
||||
|
||||
o Not really a problem, but it would be nice to have a backtrace
|
||||
window.
|
||||
|
||||
Solution: Do bt in command window?
|
||||
|
||||
o Also not really a problem, but it might be nice to have a frame/stack
|
||||
window that displays the last N words on the stack, along with
|
||||
indications about which function owns a particular frame, how the
|
||||
frame pointers are chained, and possibly the names of variables
|
||||
alongside their frame slots.
|
||||
|
||||
m68k-hp-hpux9.00:
|
||||
|
||||
o Attempting to use a Register window results in a Tcl Script Error
|
||||
"Error: Erroneous arithmetic operation". The Tcl stack trace is:
|
||||
|
||||
while executing
|
||||

||||
