IDA Pro 6.1 feature list (April 8, 2011)


  • Support for Android
    The long awaited Android support in IDA is ready!
    The new version can disassemble Android bytecode (Dalvik).
    An IDA user kindly contributed the processor module and file loader (thank you!)
    A screenshot for your pleasure:

    Dalvik disassembler is available in the Advanced Edition.

    Native ARM code can be debugged too.
    IDA Pro supports mixed ARM/Thumb code and can handle multithreaded applications:

  • 64-bit support for Bochs/GDB debuggers
    The Bochs emulating debugger is very handy for small snippets of code. Before we could handle only 32-bit code but the new version adds 64-bit support.

    Currently only the IDB mode is supported, later we plan to add PE+ support as well.

    The GDBServer module adds x64 support and works with the latest VMWare versions.

  • Loading PDB files under Linux/MacOSX
    Another long awaited feature is loading of PDB files under Linux and Mac OS X. Lack of this feature was a blocking factor for many Unix users. It is available now. Below is a screenshot made immediately after loading a PE file with PDB info on Linux:

    We added PDB support to the win32 debugger server. The Unix version of IDA connects to a remote MS Windows computer (or local Wine session) and retrieves PDB information from it.

  • String encodings
    Not only Unicode, but other character encodings can be displayed in the disassembly listing. It is even possible to specify the encoding of individual strings:

  • Low level conditional breakpoints
    Conditional breakpoints can be very slow, especially during remote debugging. We addressed this problem by creating server side low level conditional breakpoints. They speed up the debugger tremendously. In our tests breakpoints were handled more than 20 times faster, even when running the remote server on the same computer as IDA Pro. Low level breakpoints are beneifical even for local debugging, so they are available for local debuggers too:

    By the way, the screenshot shows other new breakpoint features: module relative, symbolic, and source code breakpoints. Unfortunately we had no time to finish source level debugging, so source level breakpoints are disabled for the moment.

  • Multithreaded debugger
    Another measure to speed up the debugger: we made the debugger itself multithreaded. While this feature is not visible, it makes IDA Pro more responsive and enjoyable to use. Also we introduced multithread support in the IDA kernel. The kernel is still single threaded but it is much more friendly towards multithreaded plugins.

  • Power PC improvements
    Many things were improved in the Power PC module. All the latest instructions defined by Power ISA were added, including Altivec and VSX extensions.

    Another addition is the VLE (Variable Length Encoding) instruction set, used in many embedded PPC processors.

    Also useful for embedded PPC is the new option to set a fixed value for the r13 register, commonly used as base for the small data area.

  • Wingraph is back!
    Chris Eagle has ported Wingraph32 to Qt framework (thanks!), and now we include it with all platforms, not just Windows.

  • SPU
    In addition to Dalvik, there is another new processor module in 6.1. It is the SPU (aka Synergistic Processing Unit) of the Cell BE processor, used in Sony PS3 console. This processor module is available in the Advanced Edition.

IDA Pro 6.0 feature list (Oct 1, 2010)

IDA Qt based GUI
The long awaited GUI interface for Linux and Mac OS X platforms is ready! We tried to make it as close as possible to the existing MS Windows GUI. Daniel Pistelli, who was responsible for the task, accomplished it brilliantly. The new interface turned out to be so faster and nicer that we plan to drop the old interface after a short transition period. The IDA v6.0 will ship with both old idag and new idaq. Some screenshots are a must, click on them to enlarge:

win_thumb.gif linux_thumb.gif mac_thumb.gif
