This patch adds MemProfReader::takeMemProfData, a function to return
the complete MemProf profile from the reader. We can directly pass
its return value to InstrProfWriter::addMemProfData without having to
deal with the indivual components of the MemProf profile. The new
function is named "take", but it doesn't do std::move yet because of
type differences (DenseMap v.s. MapVector).
The end state I'm trying to get to is roughly as follows:
- MemProfReader accepts IndexedMemProfData as a parameter as opposed
to the three individual components (frames, call stacks, and
records).
- MemProfReader keeps IndexedMemProfData as a class member without
decomposing it into its individual components.
- MemProfReader returns IndexedMemProfData like:
IndexedMemProfData takeMemProfData() {
return std::move(MemProfData);
}
