:mrdocs:

Identify if a vector intrinsic is overloaded on an operand or return type.

== Synopsis

Declared in `<llvm/Analysis/VectorUtils.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
bool
isVectorIntrinsicWithOverloadTypeAtArg(
    xref:llvm/Intrinsic/ID-0b.adoc[Intrinsic::ID] ID,
    int OpdIdx,
    xref:llvm/TargetTransformInfo.adoc[TargetTransformInfo] const* TTI);
----

== Description

Identifies if the vector form of the intrinsic is overloaded on the type of the operand at index `OpdIdx,` or on the return type if `OpdIdx` is ‐1. `TTI` is used to consider target specific intrinsics, if no target specific intrinsics will be considered then it is appropriate to pass in nullptr.

== Return Value

True if the vector intrinsic is overloaded on the type at `OpdIdx.`

== Parameters

| Name| Description
| *ID*
| Intrinsic identifier to classify.
| *OpdIdx*
| Operand index to check, or ‐1 for the return type.
| *TTI*
| Optional TTI used for target‐specific intrinsic rules.
