Just some minor nits from me, but generally LG.
================
Comment at: clang/include/clang/Lex/MacroInfo.h:243
- using tokens_iterator = SmallVectorImpl<Token>::const_iterator;
+ using tokens_iterator = const Token *;
+
----------------
I think this should be a `const_tokens_iterator` instead (and it's fine that we
don't expose a non-const interface for the iterator).
================
Comment at: clang/include/clang/Lex/MacroInfo.h:256
+ allocateTokens(unsigned NumTokens, llvm::BumpPtrAllocator &PPAllocator) {
+ NumReplacementTokens = NumTokens;
+ Token *NewReplacementTokens = PPAllocator.Allocate<Token>(NumTokens);
----------------
Should we assert that we've not already allocated tokens before?
================
Comment at: clang/lib/Lex/MacroInfo.cpp:33
+
+// MacroInfo is expected to take 40 bytes on platforms with an 8 byte pointer.
+template <int> class MacroInfoSizeChecker {
----------------
Should we do this dance for 32-bit systems as well?
================
Comment at: clang/lib/Lex/MacroInfo.cpp:59
+ auto ReplacementTokens = tokens();
if (ReplacementTokens.empty())
----------------
Please spell out the type.
