A set of possible enhancements or other bits

this is a misc list of additional code pieces with sources included (do not immedately merge cosider this atm more of a cherrypick area for now)

copied from here https://github.com/llvm/llvm-project/blob/8ba9ee46e465a56a54f8361703d3af7f4bc98d63/llvm/tools/llvm-pdbutil/llvm-pdbutil.cpp#L1335

Do you know what this does?

[jfm535]

well no but it seems to be important when merging pdbs and comes from this enum

enum class PdbRaw_FeatureSig : uint32_t {
  VC110 = PdbImplVC110,
  VC140 = PdbImplVC140,
  NoTypeMerge = 0x4D544F4E,
  MinimalDebugInfo = 0x494E494D,
};

so my best guess it tells the pdb how to expect the data.

[jfm535]

its also seems connected with this data

enum PdbRaw_Features : uint32_t {
  PdbFeatureNone = 0x0,
  PdbFeatureContainsIdStream = 0x1,
  PdbFeatureMinimalDebugInfo = 0x2,
  PdbFeatureNoTypeMerging = 0x4,
  LLVM_MARK_AS_BITMASK_ENUM(/* LargestValue = */ PdbFeatureNoTypeMerging)
};

this is created also where i might attempt to solve the issue of c++
files that might be part of the key
