# IDA 8.2 **IDA 8.2.221215** ***December 15, 2022*** ## IDA 8.2 Highlights ### 32-bit support in IDA64 As another step towards sunsetting 32-bit IDA which we started with 8.1, 32-bit debugging and decompilation is now possible in IDA64. For decompilation, you need to have a corresponding 32-bit decompiler license. IDA Home and IDA Free now also support decompilation of 32-bit binaries using the cloud decompiler. ![32-BIT decompiler in IDA64](https://920252027-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FXnMt6HMopakRTMzxxSKh%2Fuploads%2Fgit-blob-548d4e9916657b40c5b429677e32f3e53e9a1c46%2Fdecompiler32.png?alt=media) ### Processor module improvements * Xtensa module has been extensively reworked with the addition of various optional and macro instructions (number of supported instructions almost tripled) Most common switch patterns are recognized and marked up. ![Xtensa switch and options](https://920252027-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FXnMt6HMopakRTMzxxSKh%2Fuploads%2Fgit-blob-0d43aaf8d9126df93bb365c4ab16a7f89e753dd9%2Fxtensa.png?alt=media) Stack variables are now tracked and created in functions. ![Xtensa stack vars](https://920252027-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FXnMt6HMopakRTMzxxSKh%2Fuploads%2Fgit-blob-9ba8dc6b6b78174a226c088d0d3dfe2c46e95599%2Fxtensa_stack.png?alt=media) * RISC-V module can now disassemble vector extension instructions. ![RISC-V Vector instructions](https://920252027-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FXnMt6HMopakRTMzxxSKh%2Fuploads%2Fgit-blob-9fef7ce2d39acab96df977167c8727867aab863f%2Friscv_v.png?alt=media) ### Swift Metadata structures generated by the Swift compiler are parsed, fomatted and labeled. Some of the simple types which can be represented in IDA are imported into Local Types. ![SWIFT formatted metadata](https://920252027-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FXnMt6HMopakRTMzxxSKh%2Fuploads%2Fgit-blob-34342538e67a7d6996ec5e4bbbaa0c2989ec8f0a%2Fswift_metadata.png?alt=media) ![SWIFT formatted metadata 2](https://920252027-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FXnMt6HMopakRTMzxxSKh%2Fuploads%2Fgit-blob-574cc532be1d477b893fcb59a31677206e271154%2Fswift_metadata2.png?alt=media) ![SWIFT imported type](https://920252027-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FXnMt6HMopakRTMzxxSKh%2Fuploads%2Fgit-blob-d0ec953ce46bf6e418e3aed4682cd775179e8b1a%2Fswift_type.png?alt=media) ![SWIFT imported struct](https://920252027-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FXnMt6HMopakRTMzxxSKh%2Fuploads%2Fgit-blob-cc4571fa5f72428a7d98aa71dc326f4ac1c090f3%2Fswift_struct.png?alt=media) ### picture\_search A new plugin which can search for and display images(pictures) embedded in the current binary. ![Image search plugin](https://920252027-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FXnMt6HMopakRTMzxxSKh%2Fuploads%2Fgit-blob-3a8d062ac33f6b3535d44063fe73e5b3bad433ed%2Fpicture_search.png?alt=media) ### UI candy CSS-based IDA themes now support background images in many of IDA's views ![IDA custom background](https://920252027-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FXnMt6HMopakRTMzxxSKh%2Fuploads%2Fgit-blob-968b7361ea4711a95af572f5b236fa4e7f88f26a%2Fida_bg.jpg?alt=media) ## Full list of changes and new features: ### IDA Teams and Lumina * lumina: added support for recent MySQL versions which default to TLS connection * teams: the password for Vault is now saved securely in the OS-specific keychain * vault/lumina: allow any local MAC address to match the one specified in .lic file ### Procesor modules * XTENSA: added support for many additional instructions, registers, stack variables (thanks to Zak Escano) * XTENSA: added support for many standard switch patterns (thanks to Zak Escano) * XTENSA: detect used ABI (CALL0 or windowed) * RISC-V: added support for vector extension instructions * TRICORE: decode FTOHP and HPTOF instructions from TC1.6.2 ### File formats * macho: added USE\_SEG\_PREFIXES option to macho.cfg, which instructs IDA to use the Mach-O segment name as a prefix for IDA segment names, e.g. "\_\_TEXT:\_\_text" ### FLIRT / TILS / IDS * FLIRT: added signatures for vc1434 (Visual Studio 16.11) * FLIRT: added MFC signatures for vc1434 (Visual Studio 16.11) * FLIRT: added signatures for icl 222 (Intel C++ 2021.2) * FLIRT: added signatures for icl 2221 (Intel C++ 2021.2.1) * TIL: added a type library for Aarch64 (ARM64) UEFI 2.5 * idaclang: added "--idaclang-mangle-format" switch. it works similarly to the -G option for tilib when the user wants to set a custom name mangling format ### Standard plugins * PDB: on Windows, enabled fallback mode by default so that MSDIA is used to load legacy PDB files * picture\_search: new plugin for finding and displaying raster images embedded in the binary * svdimport: added support for cluster, derivedFrom and dim/dimIncrement peripheral attributes * svdimport: use a folder-based tree for the plugin's UI * swift: parse and format Swift metadata * swift: import simple types (enums, structs) into Local Types ### Kernel * kernel: added a new flag REFINFO\_SELFREF for offsets (base is equal to the address of the current element) ### Scripting & SDK * IDAPython: expose the C++ SDK's `processor_t` (as `ida_idp._processor_t`) * SDK: added capture\_process\_output() to capture output of an external program; * SDK: added support for lazy-loaded dirtree choosers. CH2\_LAZY\_LOADED flag can be used with dirtree-based choosers to load contents of a directory when it's expanded. * SDK: deprecated qerrcode() (errno can be accessed directly instead) ### UI * UI: added an easy way to take memory snapshot of current segment * UI: improved highlighting of matching registers on platforms which use various prefixes (e.g. @r1) * UI: in the disassembly, addresses in the line prefixes of structure or array members now increase with those members' offsets. * UI: it is now possible to attribute an image as background to the listings (IDA View, Pseudocode, ...) using CSS in themes * UI: jumping to an address in the middle of a struct or an array now positions cursor on the correct line of the disassembly listing * UI: the "Wait" dialog now only shows after a certain timeout (thereby reducing the number of interfering popping dialogs) ### Decompilers * decompiler: added an action to jump to a new pseudocode windows with 'alt+enter' shortcut * decompiler: enabled decompiling of 32-bit files in IDA64 if a corresponding 32-bit decompiler license is available ### Bugfixes * BUGFIX: arm: "set callee" (Alt-F11) failed to create cross-references for BLR instructions * BUGFIX: alpha: 'lda' instructions could cause wrong sized stack variables to be created * BUGFIX: DWARF: Debug information present in .dwz companion files (pointed to by .gnu\_debugaltlink) would be skipped when the link is absolute * BUGFIX: FLAIR: The pelf utility could crash when used with incorrect 'pelf.rtb' files * BUGFIX: IDA could crash if an array typedef was replaced by a structure of the same size * BUGFIX: IDA could fail to detect dyld (and any loaded modules) after attaching to a process on macOS 13. * BUGFIX: IDA could fail to parse Objective-C method data during debugging. * BUGFIX: IDAPython: cfunc\_t.arguments array could have function arguments in wrong order * BUGFIX: IDAPython: documentation for `ida_kernwin.Choose` callbacks was missing * BUGFIX: IDAPython: get\_reg\_vals() was not usable * BUGFIX: IDAPython: using values in the range \[128,255) as 'tag' for ida\_netnode functions, would fail * BUGFIX: ios\_deploy "symbols" phase would fail on iOS 14-16. * BUGFIX: lumina: private lumina server could fail starting with certain MySQL setups, due to case sensitivity in INFORMATION\_SCHEMA.COLUMNS fields * BUGFIX: PC: callee target was not printed for some call instructions * BUGFIX: svdimport: fixed problem with odd (+1) start addresses in segments * BUGFIX: ui/qt: IDA could crash when passed the wrong widget to `ida_kernwin.get_highlight()` * BUGFIX: ui: "size" expressions in 'Structure offset' context menu differed from 'T' hotkey * BUGFIX: ui: exporting data from hex view with non-default item width could produce wrong output * BUGFIX: UI: IDA on Windows would hang if the accessibilty option "Use text cursor indicator" was enabled * BUGFIX: ui: improvements for accessibility under Windows for "Text Cursor Indicator" on "Output" widget * BUGFIX: vault: 'hv purge' command was not usable * BUGFIX: xtensa: write acccesses for stack variables were not shown properly --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
