Member Function Documentation

◆ getAdvice()

std::unique_ptr< InlineAdvice > InlineAdvisor::getAdvice	(	CallBase &	CB,
		bool	MandatoryOnly = `false`
	)

Get an InlineAdvice containing a recommendation on whether to inline or not.

CB is assumed to be a direct call. FAM is assumed to be up-to-date wrt previous inlining decisions. MandatoryOnly indicates only mandatory (always-inline) call sites should be recommended - this allows the InlineAdvisor track such inlininings. Returns:

An InlineAdvice with the inlining recommendation.
Null when no recommendation is made (https://reviews.llvm.org/D110658). TODO: Consider removing the Null return scenario by incorporating the SampleProfile inliner into an InlineAdvisor

◆ onPassEntry()

virtual void llvm::InlineAdvisor::onPassEntry ( LazyCallGraph::SCC * SCC = nullptr )

inlinevirtual

This must be called when the Inliner pass is entered, to allow the InlineAdvisor update internal state, as result of function passes run between Inliner pass runs (for the same module).

Reimplemented in llvm::MLInlineAdvisor.

Definition at line 186 of file InlineAdvisor.h.

Referenced by llvm::InlinerPass::run(), and llvm::ModuleInlinerPass::run().

◆ onPassExit()

virtual void llvm::InlineAdvisor::onPassExit ( LazyCallGraph::SCC * SCC = nullptr )

inlinevirtual

This must be called when the Inliner pass is exited, as function passes may be run subsequently.

This allows an implementation of InlineAdvisor to prepare for a partial update, based on the optional SCC.

Reimplemented in llvm::MLInlineAdvisor.

Definition at line 191 of file InlineAdvisor.h.

Referenced by llvm::InlinerPass::run(), and llvm::ModuleInlinerPass::run().

◆ print()

virtual void llvm::InlineAdvisor::print ( raw_ostream & OS ) const

inlinevirtual

Support for printer pass.
