Redundant code has been removed from gimple-ssa-nonnull-compare.cc. This cleanup targets logic that was unreachable because COND_EXPR in this context is always either an SSA_NAME or a constant, making the specific code path unnecessary. The change simplifies the compiler’s null pointer comparison analysis.
