Synopsis

InlineCost
getInlineCost(
    CallBase& Call,
    Function* Callee,
    InlineParams const& Params,
    TargetTransformInfo& CalleeTTI,
    function_ref<AssumptionCache&(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.
