Type Aliases

Name	Description
`Location`	Memory location kind parameterized by `LocationEnum` (for example `IRMemLocation` in `MemoryEffects).`

Member Functions

Name	Description
`MemoryEffectsBase` [constructor]	Constructors
`doesAccessArgPointees`	Whether this function may access argument memory.
`doesNotAccessMemory`	Whether this function accesses no memory.
`getModRef`	`getModRef` overloads
`getWithModRef`	Get new MemoryEffectsBase with modified ModRefInfo for Loc.
`getWithoutLoc`	Get new MemoryEffectsBase with NoModRef on the given Loc.
`isTargetMemLoc`	Whether location is target memory location.
`isTargetMemLocSameForAll`	Whether the target memory locations are all the same. So it behaves as the default read/write, but for Target locations only.
`onlyAccessesArgPointees`	Whether this function only (at most) accesses argument memory.
`onlyAccessesErrnoMem`	Whether this function only (at most) accesses errno memory.
`onlyAccessesInaccessibleMem`	Whether this function only (at most) accesses inaccessible memory.
`onlyAccessesInaccessibleOrArgMem`	Whether this function only (at most) accesses argument and inaccessible memory.
`onlyAccessesInaccessibleOrTargetMem`	Whether this function only (at most) accesses inaccessible or target memory.
`onlyReadsMemory`	Whether this function only (at most) reads memory.
`onlyWritesMemory`	Whether this function only (at most) writes memory.
`operator&`	Intersect with other MemoryEffectsBase.
`operator&=`	Intersect (in-place) with other MemoryEffectsBase.
`operator-`	Subtract other MemoryEffectsBase.
`operator-=`	Subtract (in-place) with other MemoryEffectsBase.
`operator\|`	Union with other MemoryEffectsBase.
`operator\|=`	Union (in-place) with other MemoryEffectsBase.
`toIntValue`	Convert MemoryEffectsBase into an encoded integer value (used by memory attribute).
`operator==`	Check whether this is the same as other MemoryEffectsBase.
`operator!=`	Check whether this is different from other MemoryEffectsBase.
