This is Hexagon (aka QDSP6) processor module for IDA Pro disassembler. Features:

• Supports all Hexagon versions: V4, V5, V55, V60, V61, V62, V65, V66, V67, V67t
• Supports Hexagon Vector Extensions (HVX), audio extensions, NN extensions
• Supports all known instructions
• Supports ELF relocations (both static and dynamic)
• Supports IDA v7.0 and v7.2

Information on instructions was mainly gathered from LLVM, whereas missing system-level instructions were taken from Programmer's Reference Manual.

You will need the IDA 7.0 SDK or IDA 7.2 SDK (password protected).
You will also need a C++17 compiler, like Visual Studio 2015/2017, or any recent GCC or Clang.

Install target IDA SDK, copy hexagon folder into $SDK/module folder, and modify $SDK/module/makefile to include hexagon in ALLDIRS.
Build SDK, the resulting binary will be in $SDK/bin/procs/hexagon.dll.

Binaries for Windows can be found under releases

Copy the hexagon.dll file to the procs subdirectory of your IDA installation.

Start IDA, load binary and select 'Qualcomm Hexagon DSP [QDSP6]' from the processor type. In case of ELF binary just press the "Set" button.
Otherwise IDA would still sucessfully load binary, but will complain about unknown relocations.

• Switches are not recognized yet
• In case of mixed code and data the former may have incorrect packet boundaries
• Some rare relocation types are not properly recognized
• Does not distinguish between different Hexagon versions; will disassemble instructions not supported by a particular version
• IDA stores flags for two operands only, and all subsequent operands will have the same flag. For example, if the 2nd operand is an offset, then 4th will be treated as offset too.
