flobernd 0f30c1679b `KNC` instructions are only valid in 64-bit mode 2017-11-17 01:26:54 +01:00
flobernd 4195e9b0b8 Some decoder and formatter improvements
- Added `const` specifiers to some local variables
- Added KNC compatibility-mode (`ZYDIS_DECODER_MODE_KNC`) to improve decoding of ambiguous KNC/KNL+ mask-instructions
2017-11-16 22:18:20 +01:00
flobernd df101d0fe0 Decoder improvements
- Instructions which are only valid in protected-mode are now rejected, if `ZYDIS_MACHINE_MODE_REAL_16` is used
- The `scale` of memory-operands is now correctly set to `1` in 16-bit mode, if an index register was specified
