llvm::getInlineCost

Get an InlineCost with the callee explicitly specified.

Synopsis

Declared in <llvm/Analysis/InlineCost.h>

InlineCost

    CallBase& Call,
    Function* Callee,
    InlineParams const& Params,
    TargetTransformInfo& CalleeTTI,
    function_ref<AssumptionCache&(xref:llvm/Function.adoc[Function&)>] GetAssumptionCache,

Description

This allows you to calculate the cost of inlining a function via a pointer. This behaves exactly as the version with no explicit callee parameter in all other respects.

Return Value

The computed InlineCost for inlining Callee at Call.

Parameters

Name

Description

Call

Call site whose inlining cost is computed.

Callee

Callee to consider; may differ from the called function.

Params

Thresholds and knobs that tune the cost analysis.

CalleeTTI

Target transform info for the callee.

GetAssumptionCache

Callback returning the assumption cache for a function.

GetTLI

Callback returning target library info for a function.

GetBFI

Optional callback returning block frequency info, or null.

PSI

Optional profile summary used for hot/cold callsite thresholds.

ORE

Optional remark emitter for inlining diagnostics.

GetEphValuesCache

Optional callback returning the ephemeral values cache for a function.
