Member Data Documentation

◆ Calls

std::vector<Call> llvm::FunctionSummary::ParamAccess::Calls

In the per-module summary, it summarizes the byte offset applied to each pointer parameter before passing to each corresponding callee.

In the combined summary, it's empty and information is propagated by inter-procedural analysis and applied to the Use field.

◆ ParamNo

uint64_t llvm::FunctionSummary::ParamAccess::ParamNo = 0

Definition at line 813 of file ModuleSummaryIndex.h.

◆ RangeWidth

constexpr uint32_t FunctionSummary::ParamAccess::RangeWidth = 64

Referenced by llvm::generateParamAccessSummary(), and writeFunctionTypeMetadataRecords().

◆ Use

ConstantRange llvm::FunctionSummary::ParamAccess::Use {RangeWidth, true}

The range contains byte offsets from the parameter pointer which accessed by the function.

In the per-module summary, it only includes accesses made by the function instructions. In the combined summary, it also includes accesses by nested function calls.
