class DbgValueHistoryMap

Declaration

class DbgValueHistoryMap { /* full declaration omitted */ };

Description

For each user variable, keep a list of instruction ranges where this variable is accessible. The variables are listed in order of appearance.

Declared at: llvm/include/llvm/CodeGen/DbgEntityHistoryCalculator.h:27

Member Variables

public static const llvm::DbgValueHistoryMap::EntryIndex NoEntry = std::numeric_limits<unsigned long>::max()

Special value to indicate that an entry is valid until the end of the function.
