Implements a few new x86 ops
 2020-03-06 07:56:18 +02:00
Ryan Houdek 75f7bc0abd Fixes FindMSB op for the interpreter for 8bit/16bit types 
Was zexting to 32bit and thing doing a findMSB which was wrong
 2020-03-06 07:56:17 +02:00
Ryan Houdek ec5f3a6854 Fixes LEA instruction 
LEA changes behaviour based on the ordering of the prefixes on the
instruction

eg:
66 48 8d 3d ffffffff: lea rdi, [rip - 1]
48 66 8d 3d ffffffff: lea di, [rip - 1]

So we need to know the order of a few of the prefixes.
In the future this should probably be switched to a three deep stack to
have the ordering but for now this'll do

memory base at this moment
 2020-03-06 07:56:16 +02:00
Ryan Houdek c7c5d8bdd7 Cleanup the CPUID interface 
I saw LLVM using CPUID function 0x14 so I decided to fill out the map
with the basic leafs

Ryan Houdek ed12a8a242 Fixes x86 instruction decoding. 
In the case of modrm + immediate then the immediate would end up
overwriting Src1 due to the the order of the decoding.
Changes Src1 and Src2 to an array and use a variable to index the array.
Causes a bit of code churn but fixes instruction decoding and allows
easier expansion in the future for instructions that have more sources
like AVX

Ryan Houdek 9135661861 Fixes edge case when instruction declares 66h and REX.W

Ryan Houdek 8a2bf00fb6 Enforces register classes on loadstores 
Register class for loadstores must be declared upfront.
This was causing a pain point when we were trying to load <16byte in to
FPRs, which was requiring a GPR<->FPR dance.
