Member Function Documentation

◆ getInfo()

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

◆ 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.
