GCC’s loop analysis now uses INTEGRAL_NB_TYPE_P to identify integer types instead of directly comparing against INTEGER_TYPE. This allows the compiler to correctly handle extended integer types (like bitint) during loop optimization. Using the proper macro ensures correct loop analysis and optimization, fixing a latent bug and improving code generation for loops using these types.
