◆ IndexAndAttrSet

using llvm::ValueEnumerator::IndexAndAttrSet = std::pair<unsigned, AttributeSet>

Attribute groups as encoded in bitcode are almost AttributeSets, but they include the AttributeList index, so we have to track that in our map.

Definition at line 47 of file ValueEnumerator.h.

◆ ValueList
