Ryan Houdek 9870547d50 Fixes 32bit element selection for SHUFP 2020-03-06 07:56:18 +02:00
Ryan Houdek cde683eff4 Adds support for ancillary data in sendmsg 2020-03-06 07:56:18 +02:00
Ryan Houdek f645bd7901 Adds a few new IR ops 
Fixes REP CMPS. It needs to also break when ZF == 0
Fixes REPNE SCAS. It shouldn't set ZF to 0 on entry. Could result in erroneous flag setting.
Implements a few new x86 ops

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

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

Ryan Houdek 6f5b9358e2 Syscall additions and fixes

Ryan Houdek d5402bce2b Lets the block cache understand the unified address space option 
There is a limitation that all executable code must live above the
memory base at this moment
 2020-03-06 07:56:16 +02:00
Ryan Houdek 0eb5e2b332 Adds unified memory option without supporting it yet 
This allows you to set the option from the frontend but it doesn't yet
do anything.
 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
 2020-03-06 07:56:16 +02:00

Ryan Houdek d8b3e3bd84 Adds Popcount x86 instruction to dispatcher 2020-03-06 07:56:16 +02:00
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
 2020-03-06 07:56:15 +02:00
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.

Ryan Houdek a272970559 Rewrites the Dead Context Loadstore elimination passes to be more generic 
Accesses are now classified more generically, which allows them to be
optimized away more easily.
XMM still needs a special case but maybe that can be changed in the
future.
