Detailed Description

Interface to access stack safety analysis results for single function.

Constructor & Destructor Documentation

◆ StackSafetyInfo() [1/3]

StackSafetyInfo::StackSafetyInfo ( )
default

◆ StackSafetyInfo() [2/3]

StackSafetyInfo::StackSafetyInfo ( Function F,
std::function< ScalarEvolution &()>  GetSE 
)

Definition at line 789 of file StackSafetyAnalysis.cpp.

◆ StackSafetyInfo() [3/3]

StackSafetyInfo::StackSafetyInfo ( StackSafetyInfo &&  )
default

◆ ~StackSafetyInfo()

StackSafetyInfo::~StackSafetyInfo ( )
default

Member Function Documentation

◆ getInfo()

const StackSafetyInfo::InfoTy & StackSafetyInfo::getInfo ( ) const

Definition at line 799 of file StackSafetyAnalysis.cpp.

References F, and Info.

Referenced by getParamAccesses(), and print().

◆ getParamAccesses()

std::vector< FunctionSummary::ParamAccess > StackSafetyInfo::getParamAccesses ( ModuleSummaryIndex Index) const

Parameters use for a FunctionSummary.

Function collects access information of all pointer parameters. Information includes a range of direct access of parameters by the functions and all call sites accepting the parameter. StackSafety assumes that missing parameter information means possibility of access to the parameter with any offset, so we can correctly link code without StackSafety information, e.g. non-ThinLTO.

References getInfo(), Index, Info, Param, and llvm::sort().

◆ operator=()

StackSafetyInfo & StackSafetyInfo::operator= ( StackSafetyInfo &&  )
default

◆ print()

void StackSafetyInfo::print ( raw_ostream O) const
