//
// This file defines templates for core runtime data structures used by  
// instrumentation based profiling and coverage mapping. The instrumentation  
// runtime library, the compiler IR lowering, and profile reader/writer need
// to use the same template to make sure the same data structure is defined
// consistently.
//
// Examples of how the template is used:
// 1. To declare a structure:
// 
// struct ProfData {
// #define INSTR_PROF_DATA(Type, LLVMType, Name, Initializer) \
//    Type Name;
// #include "llvm/ProfileData/InstrProfData.inc"
// };
//
// 2. To construct LLVM type arrays for the struct type:
//
// Type *DataTypes[] = {
// #define INSTR_PROF_DATA(Type, LLVMType, Name, Initializer) \
//   LLVMType,
// #include "llvm/ProfileData/InstrProfData.inc"
// };
//
// 4. To construct constant array for the initializers:
// #define INSTR_PROF_DATA(Type, LLVMType, Name, Initializer) \
//   Initializer,
// Constant *ConstantVals[] = {
// #include "llvm/ProfileData/InstrProfData.inc"
// };
//===----------------------------------------------------------------------===//
