Comment (by bdubbs@…):
*** Changes in GDB 8.0
* GDB now supports access to the PKU register on GNU/Linux. The register
is
added by the Memory Protection Keys for Userspace feature which will be
available in future Intel CPUs.
* GDB now supports C++11 rvalue references.
* Python Scripting
- New functions to start, stop and access a running btrace recording.
- Rvalue references are now supported in gdb.Type.
* GDB now supports recording and replaying rdrand and rdseed Intel 64
instructions.
* Building GDB and GDBserver now requires a C++11 compiler.
For example, GCC 4.8 or later.
It is no longer possible to build GDB or GDBserver with a C
compiler. The --disable-build-with-cxx configure option has been
removed.
* Building GDB and GDBserver now requires GNU make >= 3.81.
It is no longer supported to build GDB or GDBserver with another
implementation of the make program or an earlier version of GNU make.
* Native debugging on MS-Windows supports command-line redirection
Command-line arguments used for starting programs on MS-Windows can
now include redirection symbols supported by native Windows shells,
such as '<', '>', '>>', '2>&1', etc. This affects GDB commands such
as "run", "start", and "set args", as well as the corresponding MI
features.
* Support for thread names on MS-Windows.
GDB now catches and handles the special exception that programs
running on MS-Windows use to assign names to threads in the
debugger.
* Support for Java programs compiled with gcj has been removed.
* User commands now accept an unlimited number of arguments.
Previously, only up to 10 was accepted.
* The "eval" command now expands user-defined command arguments.
This makes it easier to process a variable number of arguments:
{{{
define mycommand
set $i = 0
while $i < $argc
eval "print $arg%d", $i
set $i = $i + 1
end
end
}}}
* Target descriptions can now describe registers for sparc32 and sparc64.
* GDB now supports DWARF version 5 (debug information format).
Its .debug_names index is not yet supported.
* New native configurations
FreeBSD/mips mips*-*-freebsd
* New targets
Synopsys ARC arc*-*-elf32
FreeBSD/mips mips*-*-freebsd
* Removed targets and native configurations
Alpha running FreeBSD alpha*-*-freebsd*
Alpha running GNU/kFreeBSD alpha*-*-kfreebsd*-gnu
* New commands
flash-erase
Erases all the flash memory regions reported by the target.
maint print arc arc-instruction address
Print internal disassembler information about instruction at a given
address.
* New options
{{{
set disassembler-options
show disassembler-options
}}}
Controls the passing of target specific information to the disassembler.
If it is necessary to specify more than one disassembler option then
multiple options can be placed together into a comma separated list.
The default value is the empty string. Currently, the only supported
targets are ARM, PowerPC and S/390.
* New MI commands
-target-flash-erase
Erases all the flash memory regions reported by the target. This is
equivalent to the CLI command flash-erase.
-file-list-shared-libraries
List the shared libraries in the program. This is
equivalent to the CLI command "info shared".
