Instruction.get_dest()

Returns the destination (lvalue) if the instruction has any type of assignment

get_dest() → List[Value]

For the function:

function log10(uint256 value) internal pure returns (uint256) {
        uint256 result = 0;
        unchecked {
            if (value >= 10 ** 64) {
                value /= 10 ** 64;
                result += 64;
            }
            if (value >= 10 ** 32) {
                value /= 10 ** 32;
                result += 32;
            }
            if (value >= 10 ** 16) {
                value /= 10 ** 16;
                result += 16;
            }
            if (value >= 10 ** 8) {
                value /= 10 ** 8;
                result += 8;
            }
            if (value >= 10 ** 4) {
                value /= 10 ** 4;
                result += 4;
            }
            if (value >= 10 ** 2) {
                value /= 10 ** 2;
                result += 2;
            }
            if (value >= 10 ** 1) {
                result += 1;
            }
        }
        return result;
    }

The instruction:

result += 64;

Will return the result variable as an instance of Value-derived class, as the result is a variable, it will be of type Var.

Query Example

from glider import *
def query():
  instruction = Instructions().exec(100,300)
  dests = instruction[0].get_dest()
  for dest in dests:
    print(dest.expression)
      
  return [instruction[0]]
