AllTracedOutputs

std::unordered_map<const rvsdg::Output *, std::optional<int64_t> > jlm::llvm::aa::LocalAliasAnalysis::TraceCollection::AllTracedOutputs

Contains all outputs visited while tracing, to avoid re-visiting. If an output is visited first with a known offset, and later with a different offset, the offset is collapsed to an unknown offset, and tracing continues with that.

Definition at line 61 of file LocalAliasAnalysis.cpp.

TopOrigins

std::unordered_map<const rvsdg::Output *, std::optional<int64_t> > jlm::llvm::aa::LocalAliasAnalysis::TraceCollection::TopOrigins

Contains the outputs that have been reached through tracing, which can not be traced further. For example the output of an AllocaOperation, the result of a LoadNonVolatileOperation, or the return value of a CallOperation.
