Detailed Description

RValue - This trivial value class is used to represent the result of an expression that is evaluated.

It can be one of three things: either a simple LLVM SSA value, a pair of SSA values for complex numbers, or the address of an aggregate value in memory.

getAggregate()

static RValue clang::CodeGen::RValue::getAggregate ( Address  addr, bool  isVolatile = false  )
