# IDA 9.3sp1

This Service Pack focuses mostly on V850 Decompiler improvements and bugfixes. You can download the latest IDA installer from [My Hex-Rays portal](https://my.hex-rays.com/dashboard/download-center/installers/release).

## 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 internal error 50757 when extracting scattered UDT operands
* BUGFIX: decompiler: fixed internal error 50442 in function type analysis
* BUGFIX: decompiler: fixed internal error 51680 during chain-based variable allocation
* BUGFIX: decompiler: fixed internal error 50324 when lvar allocation spanned multiple blocks
* 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
