◆ getExpectedType()

Type * llvm::sandboxir::Utils::getExpectedType ( const Value * V) inlinestatic

\Returns the expected type of [Value](classllvm%5F1%5F1sandboxir%5F1%5F1Value.html "A SandboxIR Value has users. This is the base class.") V.

For most Values this is equivalent to getType, but for stores returns the stored type, rather than void, and for ReturnInsts returns the returned type.

◆ getExpectedValue()

\Returns the expected Value for this instruction.

For most instructions, this is the instruction itself, but for stores returns the stored operand, and for ReturnInstructions returns the returned value.
