e26971b4f0 Added missing Default 64 flag for the ENTER instruction. 
On AMD, operand size is never forced to 64 bit - instead, it only defaults to 64 bit, which means that 0x66 can be used to encode 16 bit version of the instructions.

7a0fa449bc Disassemble 4X90 as NOP as long as Rex.B is 0. Disassemble as XCHG only if Rex.B bit is set (promoting the use of R8 register). 2020-10-09 14:55:39 +03:00

d61a6fa5dd * INC/DEC do not modify the CF. 
* Fixed FXSAVE64, PUSHAD and POPAD emulation - when explicit mnemonics were added for them, emulation support was not added, thus causing emulation to stop when encountering one of these.

1d43b7b1ba Improved stack string detection heuristic: only consider registers which have been modified during emulation; registers which were provided as "input" can be ignored, as they most likely contain addresses or other data relevant to the emulated code. We are only interested in string dynamically built during our emulation. 2020-08-11 09:26:48 +03:00

ed564dba32 Specifically flag multi-byte NOP operands as not-accessed. 
New capability - bddisasm can now be instructed whether to decode some instructions as NOPs are as MPX/CET/CLDEMOTE. This is the case for instructions that are mapped onto the wide NOP space: in that case, an encoding might be NOP if the feature is off, but might be something else (even #UD) if the feature is on.
Added NdDecodeWithContext API - this becomes the base decode API; it received the input information filled in a ND_CONTEXT structure, whih has to be initialized only once, and can be reused across calls. The NdInitContext function must be used to initialize the context, as it ensures backwards compatibility by filling new options with default values.
Improvements to the README file.
