 2017-12-20 09:56:51 +01:00
flobernd e4f9054c97
Changed size of `AVX2`-gather memory operands to match `AVX512` 
The operand-size is now the size of a single element instead of the total size (like it already is for the `AVX512` gather/scatter instructions)

 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.

Added additional check for invalid AVX-512 zero masks 2017-11-29 22:47:09 +01:00
flobernd 6d690a4893 Improved file-size reduction for builds without `ZYDIS_FEATURE_EVEX`/`ZYDIS_FEATURE_MVEX` 2017-11-27 13:42:24 +01:00
Joel Höner a2cc8615ba Various minor no-libc fixes 2017-11-27 00:06:09 +01:00
Joel Höner 56f47f4863 Added support for compiling on ARM target 2017-11-26 04:38:32 +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).
