IDA 9.4sp1

IDA 9.4.260915

This Service Pack collects the fixes and improvements made since the initial IDA 9.4 release. You can download the latest IDA installer from My Hex-Rays portal.

Additions

  • arm: decode FEAT_PAuth_LR AArch64 instructions (PACIBSPPC, RETABSPPC etc.)

  • arm: show far-branch veneers as a single ADRL.X macro instruction

  • arm: recognize far-branch veneers so their thunks are named after the callee

  • dsc: added support for the DSCU_USE_SEG_PREFIXES option

  • sdk: added the Windows Qt import libraries

Improvements

  • decompiler: decompiling a function with a large number of basic blocks is now faster

  • kernel: improved speed of opening a database with many types

  • teams: the commit message input is now a multiline text area

  • teams: long git operations can now be cancelled instead of timing out

  • teams: upgraded git-ida to v1.2.0, with better support for large databases

Bugfixes

  • decompiler: fixed a crash when changing a variable's type with automatic renaming enabled

  • decompiler: fixed a hang on obfuscated functions with cyclic block chains

  • decompiler: fixed INTERR 50735 occurring when the D-810 plugin was installed

  • decompiler: user microcode changes were not applied in batch mode

  • decompiler: v850: fixed INTERR 50629 when decompiling indirect jumps or calls through the zero register

  • decompiler: fixed INTERR 52719 caused by an empty basic block

  • decompiler: fixed INTERRs 50757, 50920, 51466, 51926, 51972, 52375, 52660, 53099

  • arm: fixed decoding of some SME and SME2 instructions

  • dex: fixed a crash when loading a DEX file with a bad map offset

  • dsc: loading a shared cache region on demand could crash IDA

  • dsc: fixed __auth_stubs naming on stripped caches

  • dsc: stub thunks could be named after their caller rather than their target

  • FLAIR: the plb OMF parser could crash with a stack overflow on certain crafted input files

  • kernel: loading a file with damaged exception handling tables could crash IDA

  • tilib: listing a type library rewrote it, losing the libraries it inherits from

  • ui: fixed a crash when opening a database with a saved desktop not fitting the current screen

  • ui: fixed a crash when typing in the Names window filter box with indexer disabled

  • ui: fixed a crash when dragging a dock tab out of a single-widget floating window

  • ui: fixed a crash when highlighting the identifier under the cursor on a blank listing line

  • ui: the "Analysis" toolbar indicator wouldn't turn green again when analysis became idle

  • ui: macos: fixed a crash when searching in the Help menu

  • ui: macos: the "IDA has almost crashed" dialog no longer leaves IDA hung at 100% CPU

  • idapython: a bogus link-time dependency could prevent it from using the runtime selected by idapyswitch

  • idalib: no longer crashes on exit when close_database() was not called

  • licensing: a bad first packet from a client could crash the license server

  • ida home pc for linux failed to start with "libclpx.so could not be found"
