IDA 9.0

IDA 7.6sp1

The Service Pack 1 of IDA 7.6 is primarily a bug fixes release that provides fixes for a few errors that might affect many users.

Complete changelist:

Installer:

  • IDA Installers for Apple Silicon (arm64) don't require Rosetta2 anymore and refuse to install on Intel Macs

golang:

  • verify correctness of function boundary metadata before using it

Bugfixes

  • UI: QTreeWidget elements created from PyQt could fail to show any content

  • Decompiler: in some cases IDA crashed on right-click in the pseudocode window

  • UI: the string list cache was not restored in ida64

  • DOS: when rebasing a DOS executable using full rebase (MSF_NETNODES), segment register change points were not properly updated to the new segment bases

  • IDAPython: IDA could crash if ida_kernwin.twinpos_t.place was called for an invalid selection

  • Decompiler: 'remove return value' command could spoil the __userpurge calling convention

  • UI: In the "Structures" widget, 'Create before current structure' option wouldn't be honored anymore

  • ARM: some CSNEG instructions were incorrectly simplified to CINV or CSETM instead of CNEG

  • DWARF: When processing global variables, the DWARF plugin could erroneously delete items it shouldn't

  • UI: IDA could crash instead of showing a proper error when it detected too many copies running on the local network

  • iOS debugger could interr when querying the list of loaded dylibs

  • UI: IDA could crash when using full screen mode (F11) without a loaded database

  • UI: pressing Tab from the decompiler, to switch to a freshly-deleted disassembly view, could crash IDA

  • UI: IDA could crash when opening the shortcuts editor on macOS when some window-managing programs were running

  • UI: editing floating-point values in the hex view could fail

  • IDAPython: ida_graph.abstract_graph_t.get_edge() could crash IDA

  • UI: change accelerator for the "Optimize single stepping" option ('O' was already taken)

  • kernel: some event_listener_t hooks would not be unregistered on plugin unload which could lead to a crash later on

  • Decompiler: fixed interr 50464

  • Decompiler: fixed interr 50194

  • Decompiler: fixed interr 52379

  • Decompiler: fixed interr 50873

  • Decompiler: fixed interr 52369

  • Decompiler: fixed interr 50659

  • An explicitly specified calling convention of a virtual function would be ignored when the compiler was set to Visual Studio

  • IDA could hang on startup when running under Windows 10 Subsystem for Linux (WSL)

  • Decompiler: IDA 7.6 could crash when using 7.5 decompilers

  • UI: revert to the behavior of "create struct from data" to that of IDA 7.5 (use mangled names for struct members)

  • IDA raised interr 1827 for fixed (i.e. having PLUGIN_FIX flag) plugins with postponed init

  • golang: handle go1.16 filenames and linenumbers metadata

  • source-level debugging was broken on arm64 macOS

  • UI: the navigator wouldn't remain hidden across IDB loads

  • UI: in the "Structures" window, jumping to a type (e.g., through xref) that's not currently visible because it's not part of the selection in the left-hand list, could fail to make it visible

  • UI: if no disassembly view is available at IDB load-time, some actions (e.g., UnHide) could be unavailable in certain widgets such as "Structures"
