class MemoryDef

Declaration

class MemoryDef : public MemoryUseOrDef { /* full declaration omitted */ };

Description

Represents a read-write access to memory, whether it is a must-alias, or a may-alias. In particular, the set of Instructions that will be represented by MemoryDef's is exactly the set of Instructions for which AliasAnalysis::getModRefInfo returns "Mod" or "ModRef". Note that, in order to provide def-def chains, all defs also have a use associated with them. This use points to the nearest reaching MemoryDef/MemoryPhi.
