ΒΆbool isKnownNonZero(
    const llvm::Value* V,
    unsigned int Depth,
    const(anonymous namespace)::Query& Q)

Description

Return true if the given value is known to be non-zero when defined. For vectors, return true if every element is known to be non-zero when defined. For pointers, if the context instruction and dominator tree are specified, perform context-sensitive analysis and return true if the pointer couldn't possibly be null at the specified instruction. Supports values with integer or pointer type and vectors of integers.
