Pull Request Overview

This PR adds support for the LOAD_SMALL_INT opcode, which was introduced in Python 3.14. This opcode optimizes loading small integer constants by providing a more efficient alternative to LOAD_CONST for frequently used small integers.

  • Implements LOAD_SMALL_INT opcode handler that wraps integer values as constant variables

def LOAD_SMALL_INT(self, instr: Instruction):
int_value = instr.argval
int_var = ConstantVariable.wrap_literal(int_value, self._graph)
self.stack.push(int_var)

The LOAD_SMALL_INT function is placed before the '# 3.14 opcodes' comment at line 1004, but it is itself a Python 3.14 opcode. For better code organization and consistency, this function should be moved after the comment to group it with other 3.14 opcodes (LOAD_FAST_BORROW, NOT_TAKEN, POP_ITER).
