|
||||
|
||||
* DWARF 2
|
||||
|
||||
All configurations can now understand and use the DWARF 2 debugging
|
||||
format. The choice is automatic, if the symbol file contains DWARF 2
|
||||
information.
|
||||
|
||||
* Java frontend
|
||||
|
||||
GDB now includes basic Java language support. This support is
|
||||
only useful with Java compilers that produce native machine code.
|
||||
|
||||
* solib-absolute-prefix and solib-search-path
|
||||
|
||||
For SunOS and SVR4 shared libraries, you may now set the prefix for
|
||||
loading absolute shared library symbol files, and the search path for
|
||||
locating non-absolute shared library symbol files.
|
||||
|
||||
* Live range splitting
|
||||
|
||||
GDB can now effectively debug code for which GCC has performed live
|
||||
range splitting as part of its optimization. See gdb/doc/LRS for
|
||||
more details on the expected format of the stabs information.
|
||||
|
||||
* Hurd support
|
||||
|
||||
GDB's support for the GNU Hurd, including thread debugging, has been
|
||||
updated to work with current versions of the Hurd.
|
||||
|
||||
* ARM Thumb support
|
||||
|
||||
GDB's ARM target configuration now handles the ARM7T (Thumb) 16-bit
|
||||
instruction set. ARM GDB automatically detects when Thumb
|
||||
instructions are in use, and adjusts disassembly and backtracing
|
||||
accordingly.
|
||||
|
||||
* MIPS16 support
|
||||
|
||||
GDB's MIPS target configurations now handle the MIP16 16-bit
|
||||
instruction set.
|
||||
|
||||
* Overlay support
|
||||
|
||||
GDB now includes support for overlays; if an executable has been
|
||||
linked such that multiple sections are based at the same address, GDB
|
||||
will decide which section to use for symbolic info. You can choose to
|
||||
control the decision manually, using overlay commands, or implement
|
||||
additional target-side support and use "overlay load-target" to bring
|
||||
in the overlay mapping. Do "help overlay" for more detail.
|
||||
|
||||
* info symbol
|
||||
|
||||
The command "info symbol <address>" displays information about
|
||||
the symbol at the specified address.
|
||||
|
||||
* Trace support
|
||||
|
||||
The standard remote protocol now includes an extension that allows
|
||||
asynchronous collection and display of trace data. This requires
|
||||
extensive support in the target-side debugging stub. Tracing mode
|
||||
includes a new interaction mode in GDB and new commands: see the
|
||||
file tracepoint.c for more details.
|
||||
|
||||
* MIPS simulator
|
||||
|
||||
Configurations for embedded MIPS now include a simulator contributed
|
||||
by Cygnus Solutions. The simulator supports the instruction sets
|
||||
of most MIPS variants.
|
||||
|
||||
* Sparc simulator
|
||||
|
||||
Sparc configurations may now include the ERC32 simulator contributed
|
||||
by the European Space Agency. The simulator is not built into
|
||||
Sparc targets by default; configure with --enable-sim to include it.
|
||||
|
||||
* set architecture
|
||||
|
||||
For target configurations that may include multiple variants of a
|
||||
basic architecture (such as MIPS and SH), you may now set the
|
||||
architecture explicitly. "set arch" sets, "info arch" lists
|
||||
the possible architectures.
