GDB

Ambiguous linespecs are now handled more consistently. Uninteresting functions and files can now be skipped when stepping with the "skip function" and "skip file" commands. Commands for setting and getting the maximum length limit of a remote target hardware watchpoint were added. Python scripting was vastly improved. Many other improvements, bugfixes, and general changes were made.

GDB now understands thread names. The commands "thread name" (to assign a name) and "thread find [REGEXP]" (matching name, target ID, or extra information) were added. Python scripting support was vastly enhanced. In C++ support, exception handling was improved, and template parameters are now put in scope when debugging in an instantiation. Thread debugging of core dumps on GNU/Linux is now possible. Initial support for the OpenCL C language was introduced. Many other enhancements were made.

Support was added for the D language. C++ enhancements are supported for Argument Dependent Lookup (ADL), for static const class members, and improved User Defined Operator support. Python enhancements are access to breakpoints, symbols, symbol tables, program spaces, inferiors, threads, and a frame's code blocks, and the ability to create GDB parameters that can then be manipulated via set/show in the CLI. Furthermore, enhancements were made for tracepoints and for GDBserver. Support for the ARM Symbian platform was added. Many other enhancements as well as bugfixes were made.

Xilinx MicroBlaze and Renesas RX are now supported as targets. Support was added for multi-program debugging, allowing the debugger to control more than one program within the same GDB session. Support was added for Position Independent Executable (PIE) debugging. Many improvements were made, such as for Python, for C++ (namespace, cast operators, bug fixes), for tracepoints, for Process Record (save/restore execution log, hardware watchpoint support), and for remote protocol handling (Linux kernel debugging, new packets for tracepoint support).

Several crashes were resolved, such as those due to a stack overflow, on Solaris when reading symbols, when trying to complete the "catch exception" command, and when accessing a printing structure with a bitfield. Build failures on FreeBSD and IRIX were fixed. Thumb2 debugging support was added. A buffer overflow during function epilogue analysis was fixed. Various testsuite fixes were made.
