a75f195df3 C++: Several readability fixes: 
1. Added lots of QLDoc explanation about the role of StoreNodeOperand.
  2. Renamed '{StoreNode,ReadNode}.getAPredecessor' to 'getInner' and
     '{StoreNode,ReadNode}.getASuccessor' to 'getOuter'.
  3. Be more explicit about which type of 'StoreNode' is used in various
     places.

710d0cfc3d C++: Since we now no longer have flow from exact memory operands to LoadInstructions, we no longer have flow from PhiInstructions to LoadInstructions. We could allow flow in this particular case, but we might as well use the shared SSA library's phi edges. 2021-10-28 12:35:00 +01:00

8caff41138 C++: Throw away most of the usage of IR-computed def-use information. Instead, we rely on the shared SSA library's use-use edges. 2021-10-28 12:35:00 +01:00

8bef79502f C++: Similarly to the previous commit, we throw away the old memory-edges based way of doing read steps. Instead, we use the shared SSA library to transfer flow into a new ReadNode IPA branch, perform the necessary read steps, and then use the shared SSA library to transfer flow out of the ReadNode again. 2021-10-28 12:35:00 +01:00
Mathias Vorreiter Pedersen
5ebefe2d30 C++: Throw away the old way of doing store steps using memory edges. Instead, we introduce a StoreNode IPA branch that does store steps and instead use the shared SSA library to transfer flow into these nodes before a store step, and out of them following a sequence of store steps. 2021-10-28 12:35:00 +01:00
