¶llvm::FunctionPropertiesInfo& getCachedFPI(
    llvm::Function&) const

Declared at: llvm/include/llvm/Analysis/MLInlineAdvisor.h:46

Parameters

llvm::Function&

Parameters

const llvm::Function& F

¶int64_t getLocalCalls(llvm::Function& F)

Declared at: llvm/include/llvm/Analysis/MLInlineAdvisor.h:44

Parameters

llvm::Function& F

¶std::unique_ptr<InlineAdvice> getMandatoryAdvice(
    llvm::CallBase& CB,
    bool Advice)

Declared at: llvm/include/llvm/Analysis/MLInlineAdvisor.h:51

Parameters

llvm::CallBase& CB

bool Advice

¶virtual std::unique_ptr<MLInlineAdvice>
getMandatoryAdviceImpl(llvm::CallBase& CB)

Declared at: llvm/include/llvm/Analysis/MLInlineAdvisor.h:54

Parameters

llvm::CallBase& CB

¶const llvm::MLModelRunner& getModelRunner() const

Declared at: llvm/include/llvm/Analysis/MLInlineAdvisor.h:45

¶int64_t getModuleIRSize() const

Declared at: llvm/include/llvm/Analysis/MLInlineAdvisor.h:67

¶std::unique_ptr<InlineAdvice>
getSkipAdviceIfUnreachableCallsite(
    llvm::CallBase& CB)

Declared at: llvm/include/llvm/Analysis/MLInlineAdvisor.h:69

Parameters

llvm::CallBase& CB

¶bool isForcedToStop() const

Declared at: llvm/include/llvm/Analysis/MLInlineAdvisor.h:43

¶void onPassEntry(LazyCallGraph::SCC* SCC)

Description

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).

Declared at: llvm/include/llvm/Analysis/MLInlineAdvisor.h:34

Parameters

LazyCallGraph::SCC* SCC

¶void onPassExit(LazyCallGraph::SCC* SCC)

Description

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.

Declared at: llvm/include/llvm/Analysis/MLInlineAdvisor.h:35

Parameters

LazyCallGraph::SCC* SCC

¶void onSuccessfulInlining(
    const llvm::MLInlineAdvice& Advice,
    bool CalleeWasDeleted)

Declared at: llvm/include/llvm/Analysis/MLInlineAdvisor.h:40

Parameters

const llvm::MLInlineAdvice& Advice

bool CalleeWasDeleted

¶void print(llvm::raw_ostream& OS) const

Description

Support for printer pass

Declared at: llvm/include/llvm/Analysis/MLInlineAdvisor.h:70

Parameters

llvm::raw_ostream& OS

¶virtual ~MLInlineAdvisor()

Declared at: llvm/include/llvm/Analysis/MLInlineAdvisor.h:32
