V850

  • v850: improved o_imm-to-offset conversion for ADD, ADDI (not just MOVEA) using the regfinder

  • v850: improved resolution of many memory access patterns, including GP-relative ones

  • v850: improved PC-based (localpic) offset display

  • v850: improved regfinder for __ghssave* function calls (they set R29)

  • v850: improved setting offsets for indirect calls (setting LP followed by indirect jump)

  • v850, decompiler: added a new microcode rule for resolving localpic memory references

Debugger

  • debugger: PDB symbols can now be loaded during GDB debugger sessions

  • debugger: the win32 x86 debug server can now run under Windows XP

Bugfixes

  • BUGFIX: decompiler: fixed a crash when loading a corrupted i64 file with stale microcode

  • BUGFIX: decompiler: fixed a crash caused by deserialization of stale microcode from idb

  • BUGFIX: decompiler: fixed internal error 50898 when return type change required decompilation restart

  • BUGFIX: decompiler: fixed a hang during propagation of ABI-split operands

  • BUGFIX: ui: fixed a crash when using chooser actions dispatched via the command palette

  • BUGFIX: ui: "Jump to structure definition" from decompiler sometimes did not navigate to the expected type

  • BUGFIX: ui: Xrefs Graph could leak netnodes and duplicate data on Undo, leading to unnecessarily large database size

  • BUGFIX: ui: fixed keyboard accelerator conflict in the exit prompt dialog

  • BUGFIX: ui/sdk: get_chooser_rows could crash IDA when used on dirtree-based widgets

  • BUGFIX: ui/sdk: chooser_selection was not filled anymore for the Functions window and other dirtree-based choosers

  • BUGFIX: v850: fixed creation of bad offsets for some instructions with immediate operands

  • BUGFIX: debugger: android: ignored SIGSEGV signals used internally by the ART runtime

  • BUGFIX: microcode: removed placeholder double-click messages and hover hints in the microcode graph viewer

  • BUGFIX: switch: fixed internal error 1505 happening on some very large switches

  • BUGFIX: objc: fixed parsing of objc_methlist when it is not aligned to 8

  • BUGFIX: golang: fixed infinite loop when processing structs with self-referential pointer cycles

  • BUGFIX: indexer: "Jump Anywhere" prefix matching stopped working after renaming a function

  • BUGFIX: IDAPython: var_ref_t.getv() was wrongly removed from the decompiler bindings

  • BUGFIX: sdk: using ALLMEM memory specifier would lead to link errors

  • BUGFIX: licensing: after waking from hibernation, IDA would immediately enter read-only mode instead of retrying the connection to the license server

  • BUGFIX: licensing: users can now save the database during the license reconnection window

  • BUGFIX: licensing: better error reporting during .conf to .json migration

  • BUGFIX: licensing: fixed missing enforcement of ACL deny policies

  • BUGFIX: installer: windows: updated MSVC redistributable would not be installed on some outdated Windows systems, leading to error 0xc0000142 when starting IDA
