This is the NVPTX address space based alias analysis pass.
#define INITIALIZE_PASS(passName, arg, name, cfg, analysis)
This class stores info we want to provide to or retain within an alias query.
The possible results of an alias query.
@ MayAlias
The two locations may or may not alias.
@ NoAlias
The two locations do not alias at all.
Represent the analysis usage information of a pass.
void setPreservesAll()
Set by analyses that do not transform their input at all.
ImmutablePass class - This class is used to provide information that does not need to be run.
Representation for a specific memory location.
const Value * Ptr
The address of the start of the location.

ModRefInfo
Flags indicating whether a memory access modifies or references memory.
@ ModRef
The access may reference and may modify the value stored in memory.
@ NoModRef
The access neither references nor modifies the value stored in memory.
