◆ add() [5/9]

void AliasSetTracker::add ( const MemoryLocation Loc)

These methods are used to add different types of instructions to the alias sets.

Adding a new instruction can result in one of three actions happening:

  1. If the instruction doesn't alias any other sets, create a new set.
  2. If the instruction aliases exactly one set, add it to the set
  3. If the instruction aliases multiple sets, merge the sets, and add the instruction to the result.

AliasSet & AliasSetTracker::getAliasSetFor ( const MemoryLocation MemLoc)
