Research direction

Start by examining the existing implementation of similar x86 instructions in Manticore, likely in the platform/x86 directory. Look for functions that handle symbolic execution of instructions like MOV, ADD, etc. and use similar patterns to model LSL's behavior. Check the comments in the issue (if any) and the assignee's progress. Files to review include 'manticore/platforms/x86.py' and related modules.
