- Decoding of EVEX/MVEX instructions without a NDS/NDD-operand encoded in `.vvvv` and without a VSIB-operand will now fail, if `.v'` is != 1b
- Added information about XACQUIRE, XRELEASE and BOUND prefixes to the instruction definitions
- Fixed immediate-decoding of the `vpermil2pd` / `vpermil2ps` instruction
- Fixed operand-size and element-count of AGEN operands
- Fixed decoding of 8-bit modrm.rm register-operands
- Fixed vector-length for EVEX instructions with rounding-semantics
- Decoupled semantic operand decoding (optional) from physical instruction decoding
- Several optimizations of the internal structures
- Further preparations for MVEX-support
- Added encoding support for more X86 features (IMMs, SIB, ..)
- Added ZYDIS_ARRAY_SIZE macro
- Moved ZYDIS_MAX_INSTRUCTION_LENGTH (Decoder.h -> InstructionInfo.h)
- Renamed ZydisInstructionEncoder -> ZydisEncoderContext
- Various bug-fixes
- The instruction pointer is now directly passed to the ZydisDecoderDecodeInstruction function
- Removed the user-data pointer in the ZydisOperandInfo struct
- Added support for the BOUND prefix
- Added support for more detailed operand-actions (read, write, readwrite, cond. read, cond. write, read + cond. write, write + cond. read)
- Added operand-visibility info (explicit, implicit, hidden)
- Fixed some bugs in the prefix-decoding routines
- Removed stdbool.h dependency and introduced custom boolean-type for better portability
- Added hooking functionality to support custom instruction-formatting
- Added FormatterHooks demo that demonstrates the hooking functionality
InstructionEditor:
- Fixed issues with still non-deterministic output on code-generation
Zydis:
- Fixed operand-size of some instructions in 64-bit mode
- Fixed operand decoding of the "movq MM, GPR" instruction
- Added table-registers (GDRT, LDTR, IDTR, TR)
- Added test-registers (TR0..TR7)
- Added BNDCFG and BNDSTATUS registers
- Added MXCR register
InstructionEditor:
- The code-generator now eliminates duplicate instruction-definitions to optimize the size of the generated tables
- Fixed conflict indication for some operand type/encoding combinations
- Added conflict indication for X86Flags
* Fixed some instruction Definitions
* Implemented a primitive diffing-mode to compare different versions of the instruction-database (InstructionEditor)
