Detailed Description

Branch prediction hint utilities for performance optimization.

This file provides utility functions (qb::likely, qb::unlikely) that give branch prediction hints to the compiler. These functions can potentially improve performance by helping the compiler make better decisions about code generation for conditional branches, especially in performance-critical sections.
