Detailed Description

Represents all the compile-time information about a P4-16 program that is common to all P4 targets (in particular simple switch and psa switch).

Member Data Documentation

index

ordered_map<const IR::Parameter *, unsigned> P4::ProgramStructure::index

Maps each Parameter of an action to its positional index. Needed to generate code for actions.

scalarMetadataFields

std::map<const IR::StructField *, cstring> P4::ProgramStructure::scalarMetadataFields

We place scalar user metadata fields (i.e., bit<>, bool) in the scalarsName metadata object, so we may need to rename these fields. This map holds the new names.
