Code virtualizer for x86-64 ELF & PE binaries

Positional arguments:
  INPUT_PATH                         path to input binary to virtualize 

Optional arguments:
  -h, --help                         shows help message and exits 
  -v, --version                      prints version information and exits 
  -o, --output OUTPUT_PATH           specify the output file [default: INPUT_PATH.covirt] 
  -vcode, --vm_code_size MAX         specify the maximum allowed total lifted bytes [default: 2048]
  -vstack, --vm_stack_size SIZE      specify the size of the virtual stack [default: 2048]
  -no_smc, --no_self_modifying_code  disable smc pass 
  -no_mba, --no_mixed_boolean_arith  disable mba pass 
  -d, --show_dump_table              show disassembly of the vm instructions
