76d92e73c2 Multiple changes 
- Add support for AVX512-FP16 instructions, as per https://software.intel.com/content/www/us/en/develop/download/intel-avx512-fp16-architecture-specification.html
- Bug fix: zeroing with no masking is not supported, so return an error if we encounter such encodings
- Bug fix: ignore VEX/EVEX.W field outside 64 bit mode for some instructions
- Several other minor fixes and improvements

dbbc8b82af cmake: Space between if/else/elseif and condition 
It just looks better IMO

3495a7cc84 cmake: Various improvements, especially to the way the bddisasm package is consumed 
This should make integrating the project easier. CMake also works on Windows now.

fccf11915d Added support for Intel FRED and LKGS instructions. 2021-03-15 14:05:44 +02:00

f8a3011a49 Added support for AESDEC, AESDECLAST and AESIMC emulation, using compiler intrinsics - they will be used only if the SHEMU_OPT_SUPPORT_AES is set (so the integrator can properly check for AES-NI support in hardware). 
Fixed shemu option on Linux - make sure proper RIP is provided.

58197cc518 Removed support for PCOMMIT and CL1INVMB (not implemented by any x86/x64 CPUs), and marked MOV to/from test registers as being invalid in long mode.

144baa5140 Renamed REG_* fields to NDR_*, so that we don't conflict with _GNU_SOURCES. 2020-07-29 11:05:27 +03:00

75702e9f0d disasmtool_lix: Align the address part to the biggest one 
This way, it will always be aligned when dumping instructions:

  0 50    PUSH rax
...
 10 50    PUSH rax
...
100 50    PUSH rax

daa0d403a1 Fix the disasmtool_lix build 
The build wasn't checking properly for the compiler (was checking for C, but
this is a CPP project).
Also added a few more compiler options for GCC 9 and Clang 10.

087ffbcf95 disasmtool_lix: Add missing instructions to ins_class_to_str 2020-07-23 15:54:05 +03:00

752bc626c4 Fixed RET with immediate - the immediate is not sign-extended. 
Fixed VEX decoding in 32 bit mode - vex.vvvv bit 3 is simply ignored.
Fixed several FMA instructions decoding (L/W flag should be ignored).
Print the 64 bit immediate value in disassembly, instead of the raw immediate (note that the operand always contains the sign-extended, full immediate).
XBEGIN always uses 32/64 bit RIP size (0x66 does not affect its size).
Decode WBINVD even if it's preceded by 0x66/0xF2 prefixes.
Several mnemonic fixes (FXSAVE64, FXRSTOR64, PUSHA/PUSHAD...).
Properly decode VPERMIL2* instructions.
Fixed SSE register decoding when it is encoded in immediate.
Decode SCATTER instructions even though they use the VSIB index as source.
Some disp8 fixes (t1s -> t1s8/t1s16).
SYSCALL/SYSRET are decoded and executed in 32 bit compat modem, even though SDM states they are invalid.
RDPID uses 32/64 bit reg size, never 16.
Various other minor tweaks & fixes.
Re-generated the test files, and added some more, new tests.
