Joel Höner 31c369d3f1 Merge branch 'feature/zydis-string' into develop 
# Conflicts:
#	include/Zydis/Formatter.h
#	src/Formatter.c
 2017-12-03 22:47:01 +01:00
Joel Höner 346b7fec10 Moved internal headers 2017-12-03 22:38:20 +01:00
flobernd 02030c3b92
Various changes and refactorings 
- Moved types and functions from `FormatHelper.h/c` to `String.h/c`
- Added `ZydisMnemonicGetStringEx` function that returns the mnemonic-string as `ZydisString` struct
- Added `ZYDIS_UNUSED_PARAMETER` macro
- Fixed omitting of operands in custom formatter-hooks
- Fixed `FormatterHooks` example
- Refactored some code

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.

Added additional check for invalid AVX-512 zero masks 2017-11-29 22:47:09 +01:00
flobernd 8c69dba9db Added handling of the `ZYDIS_FEATURE_EVEX` and `ZYDIS_FEATURE_MVEX` CMake switches 
Disabling these features will only prevent some code from beeing generated. Completely removing EVEX/MVEX from the data-tables using a compiler-define is not possible at the moment (you have to re-generate the tables, if you want to save a few more bytes).
