Functions
Predicate	llvm::PPC::InvertPredicate (Predicate Opcode)
	Invert the specified predicate. != -> ==, < -> >=.
Predicate	llvm::PPC::getSwappedPredicate (Predicate Opcode)
	Assume the condition register is set by MI(a,b), return the predicate if we modify the instructions such that condition register is set by MI(b,a).
unsigned	llvm::PPC::getPredicateCondition (Predicate Opcode)
	Return the condition without hint bits.
unsigned	llvm::PPC::getPredicateHint (Predicate Opcode)
	Return the hint bits of the predicate.
Predicate	llvm::PPC::getPredicate (unsigned Condition, unsigned Hint)
	Return predicate consisting of specified condition and hint bits.
