What's new in IDA 6.95

Source: https://www.hex-rays.com/products/ida/6.95/index.shtml

Welcome to IDA 6.95!

Below are the highlights:

• We have 2 important news this time: the iPhone debugger and the PowerPC decompiler.

• The iPhone debugger uses the debugserver protocol to connect to the device and debug applications. It should work as is out of the box but we encourage you to check out the configuration file dbg_ios.cfg, it contains some important settings like SYMBOL_PATH and AUTOLAUNCH.

• The PPC decompiler is just a new decompiler that works with IDA. We had to solve many technical challenges to make it work (notably, the big endian nature of the PowerPC processor caused many inconveniences). Otherwise, the user experience should be the same as with other decompilers: just press F5 and enjoy the result. PowerPC code is especially wordy in assembler.

We hope that you will like the new additions to IDA.

• Naturally, there are many other improvements. For example, we refreshed many signature files, as well as type libraries, added new ones (64-bit type libraries were something IDA lacked since long time), and improved tilib and FLAIR utilities to work better.
As you may have guessed, while working on the PPC decompiler we had to improve many aspects of the PowerPC processor module. Now it has a new register tracking algorithm, better offset handling, more complete relocation support, etc.

The new register tracking algorithm is used for the ARM processor too, greatly improving detection of indirect call targets, switch recognition, and recognition of other common compiler idioms.

We also spent quite long time improving our venerable PC processor module. It has now an improved prolog analysis algorithm; IDA can parse the Unwind structures and apply them to the disassembly; also recognition of SEH structures and idioms has been improved a lot.

Since Intel and AMD continue to add new instructions, we too try to be up to date. All new instructions we are aware of have been added to the PC processor module.

On a completely different level, we modularized IDAPython. Now, instead of one huge idaapi module we have separate modules, each with its purpose: ida_enum, ida_funcs, ida_graph, etc.
Backward-compatibility is of course preserved through the "umbrella" idaapi module: everything should still work as it used to.

IDA 6.95 ships with Qt 5.6.0. The 5.6.x branch is a "Long Term Support" branch, that will be maintained by the Qt developers for the next three years. In addition to being an LTS, Qt 5.6.0 offers better accessibility, hopefully improving some of our users' workflow (especially on Windows.)

BUGFIX: DWARF could fail while attempting to persist arrays with huge numbers of elements (e.g. >= 0x80000000)
BUGFIX: DWARF: Don't try to apply DWARF relocations if the file is not properly relocatable
BUGFIX: DWARF: Files with DWARF relocations of type 0 (i.e., 'NONE') would prevent loading DWARF information

BUGFIX: IDA could crash while parsing header files with recursive macro definitions
BUGFIX: IDA could crash right after having loaded the dyld_shared_cache (on linux.)

BUGFIX: IDA did not remove xref and switch records when deleted debug segments
BUGFIX: IDA on Linux could crash while Tab-completing in the file chooser if 1) 'New' was selected at startup, and 2) Qt couldn't load the GTK2 theme
BUGFIX: IDA would attempt to auto-analyze binary files with no known entry point
BUGFIX: IDA would fail to keep the cursor on the instruction (or operand) when switching between flat & graph views
BUGFIX: IDAPython: IDP_Hooks instances could prevent the decompiler from working properly
BUGFIX: IDAPython: decompile_many() wouldn't accept a list of ea_t's
BUGFIX: IDAPython: running a long script that cause an IDAPython processor module to kick in, could fail to be properly interruptible because the processor module could receive the error instead of the script itself
BUGFIX: IDC's MakeLocal was broken

BUGFIX: PE: IDA would not detect DLL exports with empty names
BUGFIX: PE: IDA would show no exports if the export directory's DLL name was an empty string
BUGFIX: Pressing Alt+<key> as an accelerator to (e.g.,) toggle a checkbox in a form, while a text field is being filled and a "completion" overlay is visible, wouldn't transfer focus to the checkbox (because of the auto-completion overlay swallowing those key presses)
BUGFIX: Proximity viewer: clicking on nodes representing addresses that fall in the middle of a data item, could cause IDA to INTERR (40467)

BUGFIX: gdb: memory contents could become undefined while single stepping in the debugger
BUGFIX: gdb: some cpu flags could not be edited
BUGFIX: ida could loop endlessly trying to create a function and deleting it; overall the idea of deleting a function because it has no call xrefs is not very good; for example, functions referenced from vtable won't have any xrefs; also compilers use tail call optimization and this coverts call xrefs and jump xrefs
BUGFIX: idapython: SetFchunkOwner was broken
BUGFIX: jump-to-node-by-doubleclick in proximity view was broken

BUGFIX: ui/qt: At startup, the navigation band could fail displaying the whole program address space and only show a part
BUGFIX: ui/qt: MSG_DELAYED_UPDATE was not respected anymore (i.e., it was impossible to force a repaint of the "Output window" as soon as text was inserted)
BUGFIX: ui/qt: accessibility: JAWS could read from the wrong cursor location after jumping to another place
BUGFIX: ui/qt: refresh_navband() was not refreshing until actions (zoom, scroll) were performed
BUGFIX: unpadded size of unions was incorrectly calculated
BUGFIX: windbg: debugging 32-bit processes or crahs dumps in IDA64 would lead to a crash
BUGFIX: xcoff: x_smtyp was decoded in a wrong way, fixed
BUGFIX: DWARF: Disassembly for relocatable Mach-O files with DWARF information could be incorrect because of unhandled relocations
BUGFIX: DWARF: failed relocations into the .debug_info section, could cause the plugin to place variables at the wrong location in the disassembly
BUGFIX: DWARF: wouldn't notice buggy qualified typedefs in GCC < 4.4.1-produced PPC binaries, causing a lot of duplication in the final types list.
BUGFIX: IDAPython: Appcall could crash IDA with INTERR 30413
BUGFIX: MACHO: parsing of Objective-C information for Swift classes could be incomplete in 64-bit binaries
BUGFIX: UI: "Reload input file" function would ignore the full input path stored in IDB and only reload the file if it was present in the IDB directory

BUGFIX: fixed infinite loop during switch analysis
BUGFIX: fixed the postfix generation for duplicate names
BUGFIX: idatui.cfg was not processed completely because the default value of SCREEN_PALETTE was considered to be wrong
BUGFIX: tils: fixed wrong definitions in the Vtbl for some COM interfaces
BUGFIX: ui/qt: dragging the "Graph Overview" dock widget around could crash IDA
BUGFIX: ui/qt: navigating in the graph view wouldn't restore the zoom level & preferred position
