IDA: What's new in 6.5 ARM64 (aka AArch64) support

In September 2013 Apple released iPhone 5s with the A7 processor which supports the newest, 64-bit variant of the ARM instruction set. We are happy to announce that IDA 6.5 fully supports disassembly of ARM64 code and can load iOS 7 Mach-O binaries out of the box. The Objective-C metadata, if present, is also parsed and applied.


As usual, stack variables are created for you. We also perform limited register tracking and add cross-references so that it is easier to see, for example, what string values are loaded into registers.


Similar to x64 code, ARM64 allows you to access parts of the same register using different names (for example, W0 is the low 32 bits of the 64-bit register X0). We have implemented highlighting for ARM64 registers and in the screenshot above you can see how V11 is highlighted together with D11. This saves time when looking at complicated function, since ARM64 has 32 general-purpose and 32 SIMD registers to use.

Note: ARM64 decompilation is not available at this moment.

Rendering quality and speed improvements

We have made substantial improvements in rendering of the disassembly, both in text and graph view. You should see faster and better quality rendering. HiDPI (Retina) displays are fully supported on OS X.

Here's old IDA 6.4 on Retina display (zoomed graph view):


And the same in new IDA 6.5:

retina_65.png Database format improvements

The dreaded "Maximum number of chunks reached" message is gone. The database files can now be greater than two gigabytes, so the possible address space is limited only by the available disk space. Many other limits have been raised so now you can load huge files into IDA.

Type system

The type system has been redesigned and improved. Most of the changes are only visible to plugin writers, but users will notice:

  • support for bitfields in structures (only on C level, not in disassembly)
  • support for struct and class inheritance (only single inheritance for now)
  • improved handling of complex function prototypes and calling conventions (e.g. structures passed in registers, arguments in SSE registers etc.)
  • support for C++ → C function prototype lowering (e.g. explicit "this" and return value parameters)
  • PDB and DWARF plugins can now import more complex types using the new type system
UI improvements

Many small but useful features have been added or improved. Here's just a few:

  • Breakpoint groups

    You now can group breakpoints and disable/enable them at once. You can also export breakpoints to IDC and load them into another IDB. This can be a quick way to set breakpoints on a set of common APIs in many programs.



  • Structure offsets dialog

    The "Selection-T" dialog now supports quick filtering (Ctrl-F) of the structure list, similar to other lists in IDA. You can also add missing fields to structures based on the register+offset accesses.



  • Export data

    The new Edit → Export data command can be used to quickly export selected bytes as an array of numbers or an initialized C structure (if it is a struct instance)



  • Export to C header

    This command is now smarter: it can include necessary dependencies automatically and reorders the exported types so that the declarations or definitions appear before their use.



  • Create struct from selection

    This command used to be called "Create struct from data". We have renamed it because now it can be used not only for initialized data items, but also for a selection of stack variables in a stack frame, or a set of fields in a structure (to extract those fields into a new structure). It has also been updated to use type information, when available. For example, when converting a virtual function table (a list of function pointers), the created structure will have pointers as members, and they will have proper types if the functions had their prototypes defined.



  • Navbar and mouse wheel

    You can now use mouse wheel to scroll the navigation bar, and Ctrl-wheel to zoom it.

    • + types: added support for zero sized structs
    • + types: IDA can parse structure definitions with bitfields and store this info in the type strings
    • + types: introduced udt_type_info_t object to represent struct and union types and refactored the code to parse udt type strings (so we do not have the same code in 2 places)
    • + types: added new type-related callbacks for processor modules; they are used if PR_TINFO bit is set in the processor module; it PR_TINFO is not set, then the old callback will be used

    • + SDK: plugins can add popup menu items using add_custom_viewer_popup in two ways:
      1) On ct_popup or view_popup notifications. Such items will be automatically removed after popup execution;
      2) In any other place - the added items will remain until set_custom_viewer_popup_menu(viewer, NULL) is called (previous behavior)
    • + SDK: qctime_utc() uses Coordinated Universal Time (UTC), is equivalent to asctime(gmtime(t))
    • + SDK: removed requirement for mkidp branding for processor modules. Instead, lnames/pnames arrays are used.

    • BUGFIX: UI: non-English text in hints could be corrupted
