Package interleaved implements the interleaved devirtualization and inlining pass.

CalleeEffects appends any side effects from evaluating callee to init.

CanInline determines whether fn is inlineable.

CanInlineFuncs computes whether a batch of functions are inlinable.

CanInlineSCC computes the inlinability of functions within an SCC (strongly connected component).

GarbageCollectUnreferencedHiddenClosures makes a pass over all the top-level (non-hidden-closure) functions looking for nested closure functions that are reachable, then sweeps through the Target.Decls list and marks any non-reachable hidden closure function as dead.

InlineImpossible returns a non-empty reason string if fn is impossible to inline regardless of cost or contents.

IsBigFunc reports whether fn is a "big" function.

PGOInlinePrologue records the hot callsites from ir-graph.

TryInlineCall returns an inlined call expression for call, or nil if inlining is not possible.

InlineCall allows the inliner implementation to be overridden.

SSADumpInline gives the SSA back end a chance to dump the function when producing output for debugging the compiler itself.
