- Update from version 16.1 to 17.1
- Update of rootfile
- Changelog
17.1
* Debugging Linux programs that use x86-64 or x86-64 with 32-bit pointer
size (X32) Shadow Stacks are now supported.
* Support for the shadow stack pointer register on x86-64 or x86-64 with
32-bit pointer size (X32) GNU/Linux.
* Debugger Adapter Protocol changes
** GDB now supports the "completions" request.
* "set style" commands now supports numeric format for basic colors
from 0 to 255 and #RRGGBB format for TrueColor.
* New built-in convenience variable $_colorsupport provides
comma-separated
list of color space names supported by terminal. Each color space
name is one
of monochrome, ansi_8color, aixterm_16color, xterm_256color or
rgb_24bit.
It is handy for conditionally using styling colors based on terminal
features.
For example:
(gdb) if $_regex ($_colorsupport, ".*(^|,)rgb_24bit($|,).*")
>set style filename background #FACADE
>else
>if $_regex ($_colorsupport, ".*(^|,)xterm_256color($|,).*")
>set style filename background 224
>else
>set style filename background red
>end
>end
* UST (static tracepoint) support from gdbserver has been removed.
* Linux checkpoint code has been updated to work with multiple
inferiors.
* The gcore and gdb-add-index scripts now have a -v or --version
option, which prints the version number, and then exits. As well as
a -h or --help option, which prints each options and a brief
description.
* On systems that support linker namespaces, the output of the command
"info sharedlibraries" may add one more column, NS, which identifies
the
namespace into which the library was loaded, if more than one
namespace
is active.
* New built-in convenience variables $linker_namespace_count and
$_linker_namespace. These show the number of active linker
namespaces, and the namespace to which the current location belongs
to.
In systems that don't support linker namespaces, or if the inferior
hasn't
started yet, these always return the integer 0.
* Add record full support for rv64gc architectures
* Debugging Linux programs that use AArch64 Guarded Control Stacks is
now
supported.
* New "--binary-output" command line option instructs GDB to set the
translation mode of its stdout/stderr to binary mode. This disables
Line Feed translation. MS-Windows only.
* New commands
maintenance check psymtabs
Renamed from maintenance check-psymtabs
maintenance check symtabs
Renamed from maintenance check-symtabs
maintenance canonicalize
Show the canonical form of a C++ name.
set riscv numeric-register-names on|off
show riscv numeric-register-names
Controls whether GDB refers to risc-v registers by their
numeric names
(e.g 'x1') or their abi names (e.g. 'ra').
Defaults to 'off', matching the old behaviour (abi names).
set style emoji on|off|auto
show style emoji
Controls whether GDB can display emoji. The default is
"auto",
which means emoji will be displayed in some situations when
the host charset is UTF-8.
set style warning-prefix STRING
set style error-prefix STRING
These commands control the prefix that is printed before
warnings
and errors, respectively. This functionality is intended for
use
with emoji display, and so the prefixes are only displayed if
emoji
styling is enabled.
info linker-namespaces
info linker-namespaces [[N]]
Print information about the given linker namespace
(identified as N),
or about all the namespaces if no argument is given.
* Changed commands
info sharedlibrary
On Linux and FreeBSD, the addresses shown in the output of
this
command are now for the full memory range allocated to the
shared
library.
info threads [-gid] [-stopped] [-running] [ID]...
If no threads match the given ID(s) or filter options, GDB
now prints
No threads matched.
without printing the provided arguments. The newly added
'-stopped'
option makes GDB list the stopped threads only. Similarly,
'-running' makes GDB list the running threads only. If both
options
are given together, both stopped and running threads are
listed.
These new flags can be useful to get a reduced list when
there is a
large number of threads.
* GDB-internal Thread Local Storage (TLS) support
** Linux targets for the x86_64, aarch64, ppc64, s390x, and riscv
architectures now have GDB-internal support for TLS address
lookup in addition to that traditionally provided by the
libthread_db library. This internal support works for programs
linked against either the GLIBC or MUSL C libraries. For
programs linked against MUSL, this new internal support provides
new debug functionality, allowing access to TLS variables, due to
the fact that MUSL does not implement the libthread_db library.
Internal TLS support is also useful in cross-debugging
situations, debugging statically linked binaries, and debugging
programs linked against GLIBC 2.33 and earlier, but which are not
linked against libpthread.
** The command 'maint set force-internal-tls-address-lookup on' may
be used to force the internal TLS lookup mechanisms to be used.
Otherwise, TLS lookup via libthread_db will still be preferred,
when available.
* Python API
** GDB no longer supports Python versions less than 3.4.
** New class gdb.Color for dealing with colors.
** New constant gdb.PARAM_COLOR represents color type of a
gdb.Parameter.value. Parameter's value is gdb.Color instance.
** The memory_source argument (the second argument) has been removed
from gdb.disassembler.builtin_disassemble. This argument was
never used by GDB, and was added by mistake. The unused argument
was never documented in the GDB manual, so users should not have
been using it.
** gdb.execute has an additional 'styling' argument. When True, then
output will be styled. The default for this argument is True
when output is going to standard output, and False when output is
going to a string.
** Setting the documentation string (__doc__) of a gdb.Parameter
sub-class to the empty string, means GDB will only display the
set_doc or show_doc strings in the set/show help output.
** New gdb.ParameterPrefix class. This can be used to create 'set'
and 'show' gdb.Command prefixes, suitable for use with new
gdb.Parameters.
** Prefix commands (gdb.Command sub-classes) that don't have an
invoke method will now behave like builtin prefix commands when
invoked without a sub-command name. This means printing the help
text for all sub-commands, unless the prefix command is a 'show'
command, in which case the value of all sub-commands is printed.
** New gdb.warning() function that takes a string and prints it as a
warning, with GDB's standard 'warning' prefix.
** New attribute gdb.Value.is_unavailable, this checks for
unavailability like gdb.Value.is_optimized_out checks for
optimized out values.
* Guile API
** New type <gdb:color> for dealing with colors.
** New constant PARAM_COLOR represents color type of a value
of a <gdb:parameter> object. Parameter's value is <gdb::color>
instance.
** Eliding the #:doc string from make-parameter now means that GDB
will use a default documentation string. Setting #:doc to the
empty string for make-parameter means GDB will only display the
#:set_doc or #:show_doc strings in the set/show help output.
** Prefix commands (using make-command) that don't have a #:invoke
property will now behave like builtin prefix commands when
invoked without a sub-command name. This means printing the help
text for all sub-commands, unless the prefix command is a 'show'
command, in which case the value of all sub-commands is printed.
* New remote packets
binary-upload in qSupported reply
If the stub sends back 'binary-upload+' in it's qSupported
reply,
then GDB will, where possible, make use of the 'x' packet.
If the
stub doesn't report this feature supported, then GDB will not
use
the 'x' packet.
vFile:lstat
Return information about files on the remote system. Like
vFile:stat but if the filename is a symbolic link, return
information about the link itself, the file the link refers
to.
* Changed remote packets
qXfer:threads:read
The XML that is sent as a response can now include an "id_str"
attribute for a thread element. The attribute indicates what
GDB
should print as the target ID of the thread, for example in
the
"info threads" command or when switching to the thread.
vFile:stat
Previously, gdbserver incorrectly implemented this packet
using
lstat rather than stat. This has now been corrected. The
documentation has also been clarified.
* MI changes
** The =library-unloaded event now includes the 'ranges' field,
which
has the same meaning as for the =library-loaded event.
** The =library-unloaded event now includes the 'still-in-use'
field.
This field is 'true' when a library is unloaded (removed
from the
inferior's list of loaded libraries), but the mapping within
the
inferior's address space is retained, as the library was
mapped
multiple times, and the same mapping was being reused. In
all
other cases, this field will have the value 'false'.
* Support for stabs debugging format and the a.out/dbx object format is
deprecated, and will be removed in GDB 18.
* Configure changes
--enable-binary-file-formats=[FORMAT,...]
--enable-binary-file-formats=all
A user can now decide to only compile support for certain file
formats.
The available formats at this point are: dbx, coff, xcoff, elf, mach-o
and mips. Some targets require specific file formats to be available,
and in such cases, the configure script will warn the user and add
support anyway. By default, all formats will be compiled in, to
continue the behavior from before adding the switch.
* A new configure option was added, allowing support for the compile
subsystem to be disabled at configure time, in the form of
--disable-gdb-compile.
* A new configure option was added, allowing support for DWARF debug
information to be disabled at configure time. The flag is
--disable-gdb-dwarf-support.
* A new configure option was added, allowing support for mdebug/ecoff
debug information to be disabled at configure time. The flag to do
that is --disable-gdb-mdebug-support.
* The Alpha target now supports target descriptions.
