Changed type of implicit memory operands to `ZYDIS_MEMOP_TYPE_MEM` instead of `ZYDIS_MEMOP_TYPE_INVALID` 2018-02-23 03:44:06 +01:00
flobernd 6a8825ead2
Renamed some string-functions to match the existing naming convention (`ZydisString*`) 2018-02-23 02:23:45 +01:00
flobernd ef22aef632
Exported `ZydisString*` functions 2018-02-23 01:34:06 +01:00
flobernd 2cd7018b5b
Added `MONITORX`, `MWAITX` and `ENCLV` instructions 2018-02-19 18:59:33 +01:00
flobernd bbb864561d
More formatter changes 
- Added `ZydisFormatterFormatOperand` and `ZydisFormatterFormatOperandEx` (this won't print AVX-512/KNC decorators)
- User defined callbacks should return `ZYDIS_STATUS_SKIP_OPERAND` to omit an operand (returning `ZYDIS_STATUS_SUCCESS` without writing to the buffer is now deprecated)

 2017-12-02 06:36:12 +01:00
Joel Höner fa12ccb64b Switch to length aware string 2017-12-01 20:40:56 +01:00
flobernd 930c4df970
Removed `ZydisDecodedInstruction.instrPointer` 
The instruction-pointer was always pointing to the next instruction (which is inconsistent for branch instructions). We can't always tell IF an instruction is going to branch (for the conditional ones), so we decided to completely remove it.

You can always manually combine `instrAddress` and `length` to calculate this value.
