shouldBeDeferred()

static bool shouldBeDeferred ( Function *  Caller, InlineCost  IC, int &  TotalSecondaryCost, function_ref< InlineCost(CallBase &CB)>  GetInlineCost  )

static

Return true if inlining of CB can block the caller from being inlined which is proved to be more beneficial.

IC is the estimated inline cost associated with callsite CB. TotalSecondaryCost will be set to the estimated cost of inlining the caller if CB is suppressed for inlining.
